Description

Technical Field

[0001] This invention relates to the field of processing socket wrench components, and in particular to a socket processing system for socket wrenches. Background Technology

[0002] As a core component of ratchet wrench kits, the machining accuracy of the socket's outer surface directly affects the fit between the socket and the wrench's drive end. Currently, socket machining typically involves manual loading and clamping. The operator places the stamped socket blanks one by one into the lathe chuck, manually tightens the chuck, and then manually unloads them after machining. This traditional machining method has the following drawbacks:

[0003] 1. Low level of automation and low production efficiency: feeding, clamping and unloading all rely on manual operation, with long cycle time, making it difficult to meet the needs of mass production.

[0004] 2. Poor clamping consistency and unstable machining quality: The clamping force of manual clamping varies from person to person, and the axial positioning of the sleeve is prone to deviation, making it difficult to guarantee the consistency of the turning length and coaxiality of the outer surface.

[0005] 3. Potential operational safety hazards: Operators need to frequently approach the rotating spindle for loading and unloading, which poses a risk of mechanical injury.

[0006] 4. Difficulty in unloading through-type sleeves: Some sleeves are through-type structures at both ends. After processing, conventional unloading methods (such as air blowing or push rod) are not reliable in removing the sleeve from the clamping device, which can easily cause jamming.

[0007] In addition, some existing semi-automatic or automatic processing equipment still lacks effective integrated design in the sorting, posture detection and screening, and axial precision positioning of sleeve blanks, resulting in a low overall level of automation and poor adaptability to different specifications of sleeves.

[0008] Therefore, it is necessary to develop a sleeve processing system that integrates feeding, posture screening, automatic transfer, automatic clamping and automatic unloading functions to solve the above problems. Summary of the Invention

[0009] The purpose of this invention is to provide a socket machining system for socket wrenches to solve the technical problem of low efficiency in the turning of existing socket blanks.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A socket processing system for socket wrenches includes:

[0012] A sorting device used to sort and arrange the sleeves to be processed;

[0013] A transfer device, connected to the discharge side of the sorting device, is used to transfer the sorted sleeves to the processing station; and

[0014] Processing equipment used to clamp and process sleeves;

[0015] The processing equipment includes a lathe frame, a transmission assembly mounted on the lathe frame, a clamping mechanism coaxially connected to the front end of the hollow shaft of the transmission assembly, and a pneumatic mechanism that is poweredly connected to the clamping mechanism through the hollow shaft.

[0016] The pneumatic mechanism is used to drive the clamping mechanism to clamp or release the sleeve.

[0017] Furthermore, the clamping mechanism includes: a chuck, coaxially fixedly connected to the front end of the hollow shaft; a tightening cone sleeve A, installed at the front end of the mounting channel opened in the center of the chuck, the tightening cone sleeve A being evenly divided into at least two pieces along the circumference, used to tighten to clamp the sleeve when subjected to radial force; an annular slide rail A, opened in the chuck and coaxial with the mounting channel; a slip ring, axially slidably disposed in the annular slide rail A; a tightening cone sleeve B, coaxially connected to the inner ring of the slip ring, and sleeved on the outside of the tightening cone sleeve A; the chuck also has air passages A and B respectively communicating with the inner and outer ends of the annular slide rail A.

[0018] Furthermore, the clamping mechanism also includes a retraction valve assembly, which is installed on the inner end of the mounting channel of the chuck to assist in pushing out the sleeve. The retraction valve assembly includes: a valve block, which is fixedly disposed in the mounting channel, and the valve block has an axially extending slide rail B at its center; a slide rod, which is slidably inserted into the slide rail B; a pad, which is fixedly connected to the outer end of the slide rod and is used to abut against the end of the sleeve; and an air passage C, which is opened at the center of the slide rod and extends to the middle position of the slide rod and then passes through the side of the slide rod.

[0019] Furthermore, the unloading valve assembly also includes a return spring B, one end of which is connected to the valve block and the other end to the pad. When the slide rod is not extended, the return spring B is in a compressed state.

[0020] Furthermore, the valve block and the mounting channel are connected by a thread to adjust the axial position of the valve block.

[0021] Furthermore, the pneumatic mechanism includes an air pump, a solenoid valve connected to the air outlet of the air pump, and a dual-lumen tube assembly connected to the air outlet of the solenoid valve. The dual-lumen tube assembly includes a rotatable, sealed, and mating dual-lumen tube A and a dual-lumen tube B. The dual-lumen tube B is coaxially and fixedly connected to the hollow shaft and is used to supply air to the air passages A, B, and C respectively.

[0022] Furthermore, the sorting equipment includes: a feeding mechanism having a storage basin and a conveyor belt A with partitions for orderly lifting the sleeves from the storage basin; a conveying mechanism having a conveyor belt assembly composed of several parallel conveyor belts B, with interval grooves formed between adjacent conveyor belts B for guiding the sleeves; a screening mechanism disposed on the conveying path of the conveying mechanism for rejecting sleeves with incorrect posture; and a clamping mechanism disposed on the discharge side of the conveying mechanism for clamping the screened sleeves and transferring them to the transfer equipment.

[0023] Furthermore, the screening mechanism includes: a posture inspection component having a swingable screening plate, the lower edge of which is provided with an arched structure for a sleeve with the correct posture to pass through, and a proximity switch A being triggered when a sleeve with an incorrect posture pushes the screening plate; and a rejection component electrically connected to the proximity switch A, used to knock the sleeve with an incorrect posture off the conveyor belt assembly after receiving a trigger signal.

[0024] Furthermore, the clamping mechanism includes: an image recognition component for identifying the type of sleeve end; a displacement component A, mounted on the frame B, for providing multi-directional movement power; a gripper, mounted on the actuating end of the displacement component A, for gripping the sleeve; a rotary cylinder A, disposed between the actuating end of the displacement component A and the gripper, for driving the gripper to rotate around an axis; and an alignment component, including a telescopic cylinder D and a telescopic cylinder E, wherein the telescopic portions of the telescopic cylinder D and the telescopic cylinder E are arranged opposite each other, for applying axial force to the gripped sleeve from both ends.

[0025] Furthermore, the transfer device includes: an inclined guide rail, the entry end of which is connected to the discharge side of the sorting device; a loading plate, located at the discharge end of the guide rail, and having a placement groove for accommodating only one sleeve; a telescopic cylinder F, used to drive the loading plate to move towards the processing device; and a telescopic cylinder G, mounted on the loading plate, the telescopic part of which can extend and retract axially along the sleeve in the placement groove to push the sleeve axially to the processing device.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention achieves full automation of the entire process from loading, sorting, orientation screening, transfer, clamping to processing and unloading of sleeves through the coordinated work of sorting equipment, transfer equipment and processing equipment, which greatly improves production efficiency and processing accuracy.

[0028] 2. In the processing equipment of this invention, a pneumatic mechanism drives the clamping mechanism through a hollow shaft, realizing the automatic clamping and loosening of the sleeve. In particular, the innovative design of the expansion cone sleeve A, expansion cone sleeve B, and air passage in the clamping mechanism, together with the unloading valve group, not only achieves stable clamping of the sleeve, but also enables automatic and smooth unloading through pneumatic means after processing, solving the problems of difficult unloading and low efficiency of traditional equipment.

[0029] 3. The design of the unloading valve assembly is particularly suitable for through-type sleeves. Through the ingenious cooperation of the slide rod and air passage C, after the tightening cone sleeve is released, pressurized gas pushes the slide rod and the pad to precisely push the sleeve out of the installation channel, avoiding the problem of unloading failure caused by air pressure leakage. At the same time, the valve assembly also plays a role in precise limiting, ensuring the consistency of the sleeve pushing depth each time and improving the product processing quality.

[0030] 4. The sorting equipment uses a conveyor belt A with partitions and a conveyor belt assembly with interval grooves to achieve preliminary sorting and stable conveying of the sleeves. The screening mechanism automatically removes sleeves with incorrect posture, ensuring that the sleeves entering the subsequent workstations have the correct posture, laying the foundation for precision processing.

[0047] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figure 1 The socket processing system for socket wrenches shown includes a sorting device 100, a transfer device 200, and a processing device 300.

[0051] The sorting equipment 100 has the function of storing the sleeves to be processed and sorting them, and then conveying them in an orderly manner toward the transfer equipment 200.

[0052] The transfer device 200 is installed on the discharge side of the sorting device 100. Its function is to sequentially transfer the arranged sleeves to the processing device 300 so that the processing device 300 can automatically and accurately clamp the sleeves.

[0053] The function of the processing equipment 300 is to perform turning on the outer surface of the sleeve after it has been clamped, and to perform automatic unloading after the processing is completed.

[0054] like Figures 2-4 As shown, the sorting equipment 100 in the above scheme includes a feeding mechanism 110, a conveying mechanism 120, a screening mechanism 130, and a clamping mechanism 140.

[0055] The feeding mechanism 110 is the starting mechanism of the sorting equipment 100. Specifically, it includes a frame A111, on which a storage basin 112 is mounted. The storage basin 112 is generally bucket-shaped, allowing the sleeves within it to converge towards the center. Two sets of sprockets A113 are rotatably mounted on the frame A111. One set of sprockets A113 is mounted on the upper part of the frame A111, and the other set is mounted below the storage basin 112. One set of sprockets A113 is driven by a motor reducer A114 mounted on the frame A111, driving the coaxially connected set of sprockets A113 as the driving wheel when lifting the sleeves. It should be noted that a conveyor belt A115 is wound around the two sets of sprockets A113, and a conveyor chain 117 that meshes with the two sets of sprockets A113 is connected to the inner surface of the conveyor belt A115. Furthermore, guide grooves constrain the two sides of the conveyor belt A115 by means of pressure plates on the frame A111. When the rotating sprockets A113 drive the conveyor belt A115, the guide grooves constrain the conveyor belt A115, ensuring that the reciprocating conveyor belt A115 can pass through the bottom of the storage basin 112. In addition, several partitions 116 are evenly spaced on the outer surface of the conveyor belt A115, and the width of each partition 116 is between 0.5 and 1.5 times the diameter D of the sleeve. When the partitions 116 move together with the conveyor belt A115 from the bottom of the storage basin 112 to the top of the frame A111, each partition 116 can only drive one row of sleeves to rise, thereby ensuring that when each layer of partitions 116 passes over the high position of the frame A111 and feeds material to the rear conveying mechanism 120, the sleeves conveyed are a uniform row.

[0056] After the feeding mechanism 110 orderly lifts the sleeves in the storage basin 112 above the frame A111, the sleeves, following the movement of the conveyor belt A115, will fall into the rear conveying mechanism 120 under the action of gravity after passing the highest point. Specifically, the conveying mechanism 120 includes two sets of drive rollers A121, which are rotatably mounted at the front and rear ends of the frame A111. One set of drive rollers A121 is coaxially connected to a motor reducer B122 mounted on the frame A111 to drive the drive rollers A121 to rotate during the conveying of the sleeves. Figures 2-4 As shown, a conveyor belt assembly is wound around two sets of drive rollers A121. This conveyor belt assembly consists of several parallel conveyor belts B123, with gaps between adjacent conveyor belts B123, forming a spacer groove 124 extending along the direction of movement. Due to the presence of the spacer groove 124, when the sleeve rolls onto the conveyor belt assembly from the feeding mechanism 110, it is constrained by the spacer groove 124 and does not roll off the conveyor belt assembly. Furthermore, during subsequent conveying, the sleeve and the conveyor belt assembly can maintain their co-directional orientation.

[0057] It should be noted that although the feeding mechanism 110 has imposed corresponding constraints on the arrangement direction of the sleeves when lifting them, some sleeves may still be misaligned on the conveyor belt assembly during the process of transferring the sleeves from the feeding mechanism 110 to the conveyor mechanism 120, even with certain constraints (the gap 124 formed by the two parallel conveyor belts B123).

[0058] To prevent the skewed sleeves from entering subsequent processing steps and adversely affecting the smooth processing of the sleeves, this solution sets up a screening mechanism 130 to strictly screen the posture of each sleeve arranged on the conveying assembly.

[0059] like Figure 3 As shown, an attitude inspection component 131 and a rejection component 132 are installed along the path through which the sleeves pass in sequence. (See reference...) Figure 10The attitude inspection component 131 includes a proximity switch A1311 mounted on a frame A111 and a rotatable link A1312 mounted on the frame A111. The lower end of the link A1312 is connected to a screening plate 1313, and the lower edge of the screening plate 1313 has an upward arched passage structure. When the sleeves are aligned correctly on the conveyor belt assembly, they can pass smoothly through the passage structure below the screening plate 1313. When the sleeves are misaligned on the conveyor belt assembly (when there is an angle between the axis of the sleeve and the conveyor belt B123), the end of the sleeve will press against the lower edge of the screening plate 1313 and will be unable to pass through the arched structure at the lower edge of the screening plate 1313 and continue forward. At this time, the sleeves exert a force on the screening plate 1313 and drive it to flip. The connecting rod A1312 connected to the screening plate 1313 will flip in conjunction, driving the upper end of the connecting rod A1312 to flip and move to the position that triggers the proximity switch A1311. At this time, the proximity switch A1311 is triggered and sends a working signal to the rejection assembly 132 electrically connected to it. The rejection assembly 132 then knocks the misaligned sleeve off the conveyor belt assembly.

[0060] It should be noted that, in order to enable the attitude screening component 131 to have continuous screening capability, a return spring A1314 is also connected to the upper end of the connecting rod A1312. This allows the return spring A1314 to elastically extend and retract, driving the connecting rod A1312 back to its initial attitude after the attitude of the connecting rod A1312 changes under force. When the improperly positioned sleeve is knocked off the conveyor belt assembly, the connecting rod A1312, which has lost the sleeve's push, returns to its initial state under the action of the return spring A1314. However, if the natural recovery of the return spring A1314 is adopted, it will inevitably generate reciprocating vibration, affecting the accuracy of the screening plate 1313 in screening the sleeve's attitude. To avoid the reciprocating vibration of the return spring A1314 during its recovery causing the screening plate 1313 to swing back and forth above the conveyor belt assembly, a return spring A1314 is used. This design also includes a stop bar 1315 on the frame A111. When the connecting rod A1312 returns to its original position, the return spring A1314 is always in a stretched or compressed state, thus preventing oscillation when the return spring A1314 returns to its natural length.

[0061] Furthermore, as a preferred embodiment of the above implementation, the screening plate 1313 and the connecting rod A1312 are detachably connected to facilitate the replacement of the screening plate 1313 or the adjustment of its relative position when the sleeve model changes.

[0062] like Figure 3As shown, the rejection component 132 in the above scheme includes a telescopic cylinder A1321 mounted on the frame A111. When the telescopic cylinder A1321 extends, it can radially strike the sleeve. The telescopic cylinder A1321 is electrically connected to a proximity switch A1311. When the proximity switch A1311 is triggered, the end of the telescopic cylinder A1321 extends and strikes the improperly positioned sleeves on the conveyor belt assembly, thereby knocking the sleeves off the conveyor belt assembly and achieving the purpose of screening out the improperly positioned sleeves.

[0063] Based on the above embodiment, a guide groove 133 can be provided on the side of the conveyor belt assembly where the sleeve is knocked off, and the outlet of the guide groove 133 is connected to the storage basin 112. The rejected sleeve falls into the guide groove 133 due to inertia, and under the guidance of the guide groove 133, it returns to the storage basin 112 for reuse.

[0064] After the sleeve screening is completed, the sleeve follows the moving conveyor belt assembly to the discharge side, such as... Figure 3 , Figure 4 As shown, the clamping mechanism 140 installed on the discharge side applies clamping displacement to the sleeve.

[0065] Specifically, the clamping mechanism 140 includes a frame B141, a set of displacement components A142, and grippers 143. An image recognition component 144 is also mounted on the frame B141. The information acquisition end of the image recognition component 144 is directly facing the incoming sleeve end to identify whether the sleeve end is a connecting end or a working end. Based on the subsequent processing requirements, the component controls the displacement components A142 to adjust the sleeve to maintain its clamping state or to perform a 180° rotation adjustment.

[0066] like Figure 11 As shown, displacement assembly A142 is also mounted on frame B141, providing power for the moving sleeve. Specifically, displacement assembly A142 includes a telescopic cylinder B1421, which has a telescopic portion capable of extending and retracting along the Z-axis. A telescopic cylinder C1422 is mounted on the telescopic portion of telescopic cylinder B1421, and this telescopic cylinder C1422 has a telescopic portion capable of extending and retracting along the Y-axis. A rotary cylinder A1423 is mounted on the telescopic portion of the rotary cylinder C1422, rotating about the Y-axis. A gripper 143 is mounted on the rotating portion of the rotary cylinder A1423 to grip material located on the conveyor belt assembly when the sleeve needs to be transferred.

[0067] In order to transfer the sleeve to the next processing equipment more accurately, the clamping mechanism 140 also includes a set of alignment components 145, which can apply an axial constraint to both ends of the sleeve after the sleeve is clamped by the jaws 143, thereby allowing the axial position of the sleeve to be further adjusted.

[0068] Specifically, the alignment component 145 includes a telescopic cylinder D1451 mounted on the frame A111 and a telescopic cylinder E1452 mounted on the image recognition component 144. Both telescopic cylinders D1451 and E1452 are located directly above the conveyor belt assembly, and their telescopic parts face each other. When the sleeve is clamped, the telescopic parts of telescopic cylinders D1451 and E1452 extend simultaneously and apply an axial force to both ends of the sleeve. After the sleeve is subjected to force at both ends, it generates a matching position adjustment, achieving the function of position calibration.

[0069] In addition, it should be noted that the image recognition component 144 and the displacement component A142 in the above scheme are both connected to a lead screw adjustment component, so as to achieve convenient and quick fine adjustment according to the actual situation.

[0070] like Figure 5 As shown, the transfer device 200 includes a frame C201 on which a guide rail 202 is mounted. The guide rail 202 is inclined, and its inlet end connects to the outlet side of the sorting device 100. Sleeves transferred via the clamping mechanism 140 are arranged in an orderly manner in the groove of the guide rail 202. Simultaneously, a telescopic cylinder F203 is also mounted on the frame C201, which can extend and retract towards the processing device 300. A loading plate 204 is connected to the telescopic part of the telescopic cylinder F203. The loading plate 204 has a placement groove 205 at the outlet end of the guide rail 202, which allows only one sleeve to fall into it. It should be noted that the placement groove 205 has a high degree of fit with the shape of the sleeve to apply an effective positional constraint to the sleeve falling into it. Meanwhile, a telescopic cylinder G206 is also installed on the loading plate 204. The telescopic part of the telescopic cylinder G206 can extend and retract along the axial direction of the sleeve in the placement groove 205, so as to push the sleeve in the placement groove 205 out axially.

[0071] like Figure 6 , Figure 7 As shown, the processing equipment 300 includes a lathe frame 301, on which a transmission assembly 302 is mounted. A hollow shaft 303 is configured in the transmission assembly 302 as an external output medium. A clamping mechanism 310 is configured at the front end of the hollow shaft 303 to precisely clamp the sleeve transferred from the transfer device 200.

[0072] like Figure 6 , Figure 7As shown, a pneumatic mechanism 320 is provided at the rear end of the hollow shaft 303. The pneumatic mechanism 320 is poweredly connected to the clamping mechanism 310 through the hollow shaft 303 to drive the clamping mechanism 310 to perform a clamping operation on the sleeve, and after the sleeve is processed, drive the clamping mechanism 310 to release the sleeve and push the sleeve out of the clamping mechanism 310 by itself.

[0073] like Figure 6 As shown, a displacement assembly B304 is mounted on the lathe frame 301. This displacement assembly B304 comprises an apron capable of telescopic movement along the X-axis and a feed box capable of movement along the Z-axis. The feed box is mounted on the apron, and the two are superimposed to form a motion actuator capable of driving the tool holder 305 to move in the XZ plane. The tool holder 305 is also mounted on the apron, and a cutting tool 306 is detachably and adjustably mounted on the tool holder 305. When machining the outer surface of the sleeve, the motion actuator drives the cutting tool 306 to perform orderly turning on the sleeve surface.

[0074] It should be noted that the hollow shaft 303, the clamping mechanism 310, and the pneumatic mechanism 320 form the core of the automatic clamping and automatic unloading in the sleeve processing of this solution.

[0075] Specifically, such as Figure 9 , Figure 12 , Figure 13 As shown, the clamping mechanism 310 includes a chuck 311 with spoke-shaped locking blocks 3111 on its edge. A groove adapted to the locking blocks 3111 is formed at the front end of the hollow shaft 303. The chuck 311 is embedded in the groove to achieve a non-rotatable coaxial connection with the hollow shaft 303. At least one locking bolt 312 is installed on the outer end of the hollow shaft 303. After the locking bolt 312 enters the hollow shaft 303, its end abuts against the outer edge of the chuck 311 to prevent the chuck 311 from dislodging from the groove. An axially extending mounting channel 3112 is formed at the center of the chuck 311. A tightening cone sleeve A313 is installed at the front end of the mounting channel 3112. The tightening cone sleeve A313 is divided into at least two pieces to tighten under radial force, thereby clamping the sleeve passing through it. Simultaneously, an annular slide rail A3113, coaxial with the chuck 311, is also provided in the chuck 311. The inner end of the annular slide rail A3113 is connected to the air passage A3114 in the chuck 311, and the outer end of the annular slide rail A3113 is connected to the air passage B3115 in the chuck 311. A slip ring 314 is also axially slidable within the annular slide rail A3113. By introducing pressurized gas into the air passage A3114 or the air passage B3115, the slip ring 314 is driven to slide axially within the annular slide rail A3113. See Figure 13As shown, the inner ring of the slip ring 314 is coaxially connected to the expansion cone sleeve B315. The expansion cone sleeve B315 is sleeved on the outside of the expansion cone sleeve A313, and the expansion and loosening state of the expansion cone sleeve A313 is controlled by axial movement.

[0076] Specifically, by supplying pressurized gas to the air passage A3114, the slip ring 314 slides towards the outer end of the annular slide rail A3113, thereby causing the expansion cone sleeve A313 to tighten, and the sleeve inserted into the expansion cone sleeve A313 is clamped and constrained. Conversely, by introducing pressurized gas into the air passage B3115, the slip ring 314 moves towards the inner end of the annular slide rail A3113, thereby causing the expansion cone sleeve B315 to retract from the expansion cone sleeve A313. After losing the constraint from the expansion cone sleeve B315, the expansion cone sleeve A313 elastically recovers, thus releasing the clamping of the sleeve, facilitating the removal of the sleeve from the clamping mechanism 310 after processing.

[0077] In the above scheme, a detachable connection is adopted between the clamping mechanism 310 and the hollow shaft 303. The purpose is to facilitate the replacement of clamping mechanisms 310 with various clamping specifications, so as to adapt to the processing needs of more specifications of sleeves.

[0078] It should be noted that, to further improve the automation level of sleeve processing, i.e., to achieve automatic sleeve unloading after processing, this solution uses a shared air source for the chuck 311's mounting channel 3112 and air passage B3115. While the pneumatic mechanism 320 supplies air to air passage B3115, an axial pneumatic thrust is also applied to the inner end of the sleeve in the chuck 311 through mounting channel 3112. When the shrinking cone sleeve B315 is removed from the shrinking cone sleeve A313, the shrinking cone sleeve A313 loosens, and the unconstrained sleeve is pushed out by the pressurized gas blown out of mounting channel 3112, completing the automatic unloading process.

[0079] It should be noted that in actual production, there are various specifications for sleeves. Some of these sleeves have an axially continuous structure between the connecting end and the working end. In this case, if pressurized gas is blown directly onto the inner end of the sleeve through the installation channel 3112, not only will the sleeve fail to be blown out, but it will also cause air pressure leakage, preventing the expansion tapered sleeve B315 from completing the unloading step.

[0080] To accommodate the above situation, this solution also installs a set of unloading valve assembly 330 on the inner end of the installation channel 3112, such as... Figure 13As shown, the unloading valve assembly 330 includes a valve block 331. An axially extending slide rail B3311 is formed at the center of the valve block 331. A slide rod 332 is slidably inserted into the slide rail B3311. A pad 333 is connected to the outer end of the slide rod 332. A gap is left between the pad 333 and the mounting channel 3112 for pressurized gas to be blown out. Simultaneously, an air passage C3321 is formed at the center of the slide rod 332. This air passage C3321 extends to the middle of the slide rod 332, then extends to the side of the slide rod 332 and passes through it.

[0081] When the sleeve enters the installation channel 3112, its inner end abuts against the pad 333. When it is necessary to remove the sleeve from the clamping mechanism 310, the pneumatic mechanism 320 at the rear delivers pressurized gas, which simultaneously enters air passages B3115 and C3321. At this time, the expansion cone sleeve B315, through the pressurized gas in air passage B3115, first retracts from the expansion cone sleeve A313, causing the expansion cone sleeve A313 to loosen from the sleeve. As the sleeve loses the constraint force from the expansion cone sleeve A313, the sleeve has the ability to move axially relative to the clamping mechanism 310. The pressurized gas entering air passage C3321 pushes the slide rod 332 to move axially. During this process, the axially moving slide rod 332 drives the pad 333 to move synchronously, and finally pushes the sleeve out of the installation channel 3112 through the pad 333, realizing the automatic unloading of the sleeve. It should be noted that when the slide rod 332 moves axially to a certain distance, the air outlet of the air passage C3321 on the surface of the slide rod 332 is exposed, completing the pressure relief. At this time, the slide rod 332 has completed its exit stroke, preventing the slide rod 332 from coming out of the slide rail B3311.

[0082] It should be noted that by setting the unloading valve assembly 330 within the installation channel 3112, the insertion depth of the sleeve is precisely limited. Specifically, the depth of the sleeve entering the installation channel 3112 depends primarily on the extension and retraction stroke of the telescopic cylinder G206 in the transfer device 200. However, when pushing the sleeve, the sleeve itself gains kinetic energy, and the sleeve is simultaneously subjected to frictional force between itself and the tightening cone sleeve A313 in the clamping device. The frictional force between each sleeve and the tightening cone sleeve A is inconsistent, making it difficult to precisely control the insertion depth of the sleeve. This results in variations in the machined area on the outer surface of the sleeve, negatively impacting product consistency.

[0083] After adding the unloading valve assembly 330, the stroke of the telescopic cylinder G206 only needs to be preset so that the telescopic cylinder G206 retracts after pushing the sleeve into place (the inner end of the sleeve abuts against the pad 333 and continues to apply pressure until the expansion cone sleeve A313 clamps the sleeve), thus achieving precise positioning of the sleeve. Preferably, the valve block 331 and the installation channel 3112 in this solution are threadedly connected, meaning that the valve block 331 can adjust its axial position in the installation channel 3112 to adapt to the requirements of various sleeve insertion depths.

[0084] Furthermore, it should be noted that, to improve the stability of the pad 333 when it pops out and to further prevent the slide rod 332 from dislodging from the slide rail B3311, a return spring B334 is also provided in the valve block 331. One end of the return spring B334 is connected to the valve block 331, and the other end is connected to the pad 333. When the slide rod 332 is not extended, the return spring B334 is in a compressed state. When the sleeve needs to be removed, the return spring B334 pops out, thereby pushing out the pad 333, and the sleeve is also pushed out. After the elastic potential energy of the return spring is released, it will exert a pulling force on the pad 333 to prevent the slide rod 332 connected to the pad 333 from dislodging.

[0085] like Figure 8 , Figure 9 As shown, the pneumatic mechanism 320 in this solution includes an air pump 321, with two exhaust pipes at the air outlet. Each exhaust pipe is equipped with a solenoid valve 322 that controls its opening and closing. It also includes a dual-chamber tube A323, with the outlets of the two solenoid valves 322 connected to different chambers on the dual-chamber tube A323. Furthermore, it includes a dual-chamber tube B324, whose ends are coaxially sealed and fitted together with the dual-chamber tube A323, forming a relatively rotating dual-chamber tube assembly.

[0086] It should be noted that the end of the double-lumen tube B324 is connected to the hollow shaft 303 via a flange, thus ensuring the static stability of the outer double-lumen tube A323 while the hollow shaft 303 rotates at high speed, driving the double-lumen tube B324. Figure 9 As shown, the inner cavity of the dual-lumen tube B324 is connected to the central channel of the hollow shaft 303, achieving direct communication with air passages B3115 and C3321. The outer cavity of the dual-lumen tube B324 is connected to air passage D3031, which is located in the hollow shaft 303. Air passage D3031 is connected to air passage A3114, ultimately achieving separate air supply between air passage A3114 and air passages B3115 and C3321. Working principle:

[0087] 1. Material loading and sorting stage:

[0088] First, the sleeves to be processed are poured in batches into the storage basin 112 of the sorting equipment 100. The motor reducer A114 is started, driving the sprocket A113 to rotate, thereby moving the conveyor belt A115. The partitions 116 on the conveyor belt A115 scoop up the sleeves from the bottom of the storage basin 112, and as the conveyor belt A115 is lifted, the sleeves are arranged in an orderly manner on the partitions 116 and then lifted upwards. After passing the highest point, the sleeves roll down onto the conveyor belt assembly of the conveying mechanism 120 under the action of gravity. The conveyor belt assembly consists of multiple parallel conveyor belts B123, and the gaps 124 between adjacent conveyor belts B123 guide and constrain the sleeves, keeping them in their approximate direction and conveying them forward.

[0089] 2. Screening and posture adjustment stage:

[0090] As the sleeves pass through the screening mechanism 130 along with the conveyor belt assembly, the attitude inspection component 131 checks the attitude of each sleeve. If the sleeve's attitude is correct (its axis is basically aligned with the conveying direction), its end can smoothly pass through the arched structure at the lower edge of the screening plate 1313. If the sleeve's attitude is skewed, its end will press against the screening plate 1313, forcing the connecting rod A1312 to flip, thereby triggering the proximity switch A1311. The proximity switch A1311 then sends a signal to the telescopic cylinder A1321 of the rejection component 132. The telescopic cylinder A1321 extends and knocks the sleeves with incorrect attitude off the conveyor belt assembly. The rejected sleeves slide back into the storage basin 112 along the guide groove 133, waiting to be reloaded. Sleeves with correct attitude continue to be conveyed forward to the discharge side.

[0091] 3. Clamping and Transfer Stage:

[0092] When the sleeve reaches the end of the conveyor belt assembly, the image recognition component 144 of the clamping mechanism 140 first identifies the type of the sleeve end (connecting end or working end), and adjusts the position of the gripper 143 through the displacement component A142 and the rotary cylinder A1423 according to the subsequent processing requirements. After the gripper 143 clamps the sleeve, the telescopic cylinders D1451 and E1452 of the aligning component 145 extend, applying axial thrust to the sleeve from both ends to achieve precise adjustment of the sleeve's axial position. Subsequently, the displacement component A142 moves the sleeve with the adjusted posture and position to the guide rail 202 of the transfer device 200. The sleeve slides down the inclined guide rail 202 by gravity into the placement groove 205 of the loading plate 204 and is arranged sequentially. Then, the telescopic cylinder G206 extends, axially pushing the sleeve in the placement groove 205 and sending it into the clamping mechanism 310 of the processing equipment 300.

[0093] 4. Clamping and processing stage:

[0094] The sleeve is pushed into the mounting channel 3112 of the clamping mechanism 310 until its inner end abuts against the pad 333 of the unloading valve assembly 330. At this time, the pneumatic mechanism 320 starts to work: pressurized gas is introduced into the air passage A3114 through the dual-chamber tube assembly. The pressurized gas enters the inner end of the annular slide rail A3113, pushing the slip ring 314 to slide to the outer end of the annular slide rail A3113. The slip ring 314 drives the expansion cone sleeve B315 to move synchronously, forcing the expansion cone sleeve A313 to contract radially, thereby tightly clamping the sleeve. At the same time, since the end of the sleeve has abutted against the pad 333, its axial position is also precisely defined.

[0095] After clamping is completed, the transmission assembly 302 of the processing equipment 300 starts, driving the hollow shaft 303 and the clamping mechanism 310 to rotate at high speed. At the same time, the displacement component B304 drives the tool holder 305 to move, so that the tool 306 performs turning machining on the outer surface of the sleeve according to the preset program.

[0096] 5. Unloading and resetting stage:

[0097] After the sleeve is processed, the pneumatic mechanism 320 switches the air supply path: it stops supplying air to air passage A3114 and instead simultaneously supplies pressurized gas to air passages B3115 and C3321.

[0098] First, the pressurized gas entering the air passage B3115 enters the outer end of the annular slide A3113, pushing the slip ring 314 to slide towards the inner end of the annular slide A3113, causing the expansion cone sleeve B315 to disengage from the expansion cone sleeve A313. The expansion cone sleeve A313 then returns to its original position due to its own elasticity, thereby releasing the clamping force on the sleeve.

[0099] Simultaneously, pressurized gas entering air passage C3321 enters the central air passage of slide rod 332, pushing slide rod 332 outward along slide rail B3311. Slide rod 332 drives pad 333 to push the loosened sleeve outward into mounting channel 3112, achieving automatic unloading. When slide rod 332 moves to the point where the lateral air outlet of air passage C3321 is exposed, the pressurized gas is released, and slide rod 332 stops moving. Subsequently, under the action of return spring B334, slide rod 332 and pad 333 automatically reset, waiting for the next processing cycle. Thus, a complete sleeve processing flow is completed.
