Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0055] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0056] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0057] like Figures 1-16 As shown, this embodiment provides an automatic clamping device for anodized workpieces with titanium alloy bolt surface treatment, the clamping device includes a clamping assembly 100 and a bolt feeder 200, the clamping assembly 100 and the bolt feeder 200 are connected by a feeding air pipe 300, the bolt feeder 200 conveys the clamping bolts 180 to be processed one by one to the clamping assembly 100, so that the clamping assembly 100 clamps them to the clamping spring 150.

[0058] The clamping assembly 100 includes a clamping spring 150 and a pusher, wherein the clamping spring 150 can rotate and move downward along its spiral direction, and the pusher can push the clamping bolts 180 delivered by the feeding air pipe 300 into the gap of the clamping spring 150 one by one as the clamping spring 150 moves downward. The clamping spring 150 gathers multiple clamping bolts 180 on itself through the clamping force between adjacent coils of the spring to form a string-like clamping structure.

[0059] The clamping assembly 100 and clamping device provided in this embodiment can use a pusher to insert the clamping bolts 180 to be processed one by one into the spirally downward-moving clamping springs 150, forming a string-like clamping structure of the clamping springs 150 to facilitate surface treatment of workpieces. This clamping device enables flexible and automatic clamping of discrete products, significantly reducing labor while ensuring clamping stability and improving clamping efficiency.

[0060] In the clamping assembly 100 provided in this embodiment, a roller 190 is provided on the side of the clamping spring 150. The outer wall of the roller 190 can be made of a material with a certain degree of friction, such as rubber, preferably a flexible damping material, so that the roller 190 can drive the clamping spring 150 to rotate through the friction force of its circumferential side wall. Specifically, the roller 190 can be driven to rotate by a clamping motor 191 or other power device.

[0061] At the same time, at least one supporting roller 1120 is provided on the side of the clamping spring 150. This at least one supporting roller 1120 is rotatable along its axis. At least one annular protrusion 1121 is provided along its circumference. This at least one annular protrusion 1121 can be inserted into the gap of the clamping spring 150 to provide guidance for the spiral downward movement of the clamping spring 150. The number of supporting rollers 1120 and annular protrusions 1121 can be set as needed.

[0062] Illustratively, the clamping assembly 100 provided in this embodiment includes two support rollers 1120, each support roller 1120 is provided with two annular protrusions 1121 at intervals, and the positions of the annular protrusions 1121 of the two support rollers 1120 need to be configured according to the positional relationship between them and the gap between the clamping spring 150.

[0063] Of course, in other embodiments, the above structure can also be used to achieve the rotation and downward movement of the clamping spring 150. For example, the clamping spring 150 can be installed in a cylindrical structure, and a push-down member is provided on the top of the clamping spring 150 to press the clamping spring 150 downward to move it downward. At least one rod-shaped structure is inserted into the gap of the clamping spring 150 to cause the clamping spring 150 to rotate and move downward in a spiral manner. Of course, the push-down member and the rod-shaped structure can also be combined with the roller 190 and the support roller 1120 to achieve the spiral downward movement of the clamping spring 150. This is not limited here.

[0064] The automatic clamping equipment for anodizing titanium alloy bolt surface treatment workpieces provided in this embodiment also includes an assembly component for assembling a support roller 1120. Specifically, the assembly component includes a U-shaped assembly plate 1131 and two side plates 1132 arranged around the outer periphery of the support roller 1120. The assembly plate 1131 is hinged to one of the two side plates 1132 via an articulated structure such as a hinge, and is connected and fixed to the other side plate 1133. Positioning plates 1134 are fixed to the upper and lower sides of the assembly plate 1131 via fasteners such as bolts. The support roller 1120 is arranged between the two positioning plates 1134 and is rotatably connected to the positioning plates 1134. This design allows equipment maintenance personnel and other personnel to more conveniently inspect and replace the support roller 1120 to accommodate clamping springs 150 of different pitches.

[0065] In this embodiment, the engaging member 1133 is an L-shaped block, one end of which is hinged to the side plate 1132, and the other bent end is buckled onto the assembly plate 1131. A spring structure provides the thrust for the engagement of the block. For example, the block can be rotatably connected to the side plate 1132 via a shaft fixed to the side plate 1132, and a spring structure such as a torsion spring maintains the block's engagement with the assembly plate 1131.

[0066] Of course, in other embodiments, other types of hinged and elastic structures may be used to achieve the aforementioned functions of the assembly. For example, the clamping block and the side panel 1132 may be hinged together using a hinge structure, and an elastic structure such as a spring disposed on the side of the clamping block facing away from the side panel 1132 may be used to push the clamping block toward the side panel 1132 to maintain the clamping block in the engaged state.

[0067] Of course, in other embodiments, other forms of assembly components may be used to define the position of the support roller 1120. For example, the assembly plate 1131 and the two side plates 1132 are assembled and fixed by fasteners such as bolts. When replacing or repairing the support roller 1120, the assembly plate 1131 and the support roller 1120 can be removed by removing the bolts.

[0068] As a preferred embodiment, the automatic clamping device for anodized titanium alloy bolt surface treatment workpieces provided in this embodiment further includes a sleeve 151, which is vertically disposed above the roller 190 and is used to contain the clamping spring 150, thereby maintaining the clamping spring 150 in an upright position above the roller 190. As a preferred embodiment, a notch is formed in the side of the sleeve 151, extending vertically therethrough, to facilitate observation of the position of the clamping spring 150.

[0069] In the clamping assembly 100 provided in this embodiment, the ejector includes a main body 1101, a clamp 110 and an ejector rod 111, wherein:

[0070] The clamp 110 consists of two openable, single jaws 1103, each rotatably connected to side panels 1102 on either side of the main body 1101 via a rotating shaft or other structure. Specifically, one end of each jaw 1103 is rotatably connected to the upper and lower portions of the side panels 1102, located on the upper and lower sides of the main body 1101, while the other end extends to the front end of the main body 1101. Grooves on the adjacent side walls of the two jaws 1103 form a cavity 1104 for accommodating the clamping bolts 180. The front end of this cavity 1104 has a tapered structure, and an opening extending through the clamp 110 is located at the front end. A feed air pipe 300 is fixed to the side of the main body 1101 and communicates with the cavity 1104. The clamping bolts 180 are fed into the cavity 1104 one by one via the feed air pipe 300.

[0071] The push rod 111 is inserted from the main body 1101 and the rear end of the clamp 110 to the front end opening of the clamp 110, passes through the accommodating cavity 1104, and can move back and forth along the main body 1101 and the clamp 110. The push rod 111 can poke the clamping bolt 180 located in the accommodating cavity 1104 out of the front end opening of the accommodating cavity 1104, so that the clamping bolt 180 is squeezed into the gap of the clamping spring 150, and the two single clamps 1103 are pushed open by the clamping bolt 180 when the clamping bolt 180 is poked out.

[0072] The automatic clamping equipment for anodized workpieces with surface treatment of titanium alloy bolts provided in this embodiment also includes a pushing power assembly 1110, which includes a base plate 1111, a slide rail 11111 arranged on the base plate 1111, and a first slider 1112 and a second slider 1113 arranged on the slide rail 11111; wherein the clamp 110 is arranged on the second slider 1113, and the push rod 1111 is arranged on the first slider 1112.

[0073] A first guide rod 1114 is provided between the first slider 1112 and the second slider 1113. The first guide rod 1114 is fixedly connected to one of the first slider 1112 or the second slider 1113 and is slidably inserted on the other; or, the first guide rod 1114 is slidably inserted into the first slider 1112 and the second slider 1113; a raised stopper (not shown) is provided at the sliding end of the first guide rod 1114; a first buffer spring 11141 is wound around the outside of the first guide rod 1114 located between the first slider 1112 and the second slider 1113, and the first buffer spring 11141 is in a compressed state.

[0074] During the operation of the device, the first slider 1112 can be in the power device, such as Figure 4 As shown in the figure, the pushing cylinder 1116 moves forward under the push of the telescopic rod 11161 fixed on the base plate 1111, and pushes the second slider 1113 and the clamp 110 forward under the pushing action of the first buffer spring 11141; when the second slider 1113 stops moving under the abutment of the stopper 11131 fixed on the base plate 1111, the telescopic rod 11161 of the pushing cylinder 1116 pushes the first slider 1112 to squeeze the first buffer spring 11141 and continue to move forward until the pushing rod 111 pokes the clamping bolt 180 out from the front end of the clamp 110.

[0075] Among them, the block 11131 is as follows Figure 6 As shown, it can be composed of a fixing block 111311 fixed on the base plate 1111 and a blocking rod 111312 provided on the fixing block 111311. The blocking rod 111312 can be fixed to the fixing block 111311; preferably, the blocking rod 111312 can be slidably inserted into the fixing block 111311, and raised blocking blocks are provided at both ends of the blocking rod 111312, and a compression spring (not shown) is provided between the fixing block 111311 and the blocking block at one end of the blocking rod 111312 close to the second slider 1113.

[0076] First slider 1112 can be pulled backward by the power device. When the distance between first slider 1112 and second slider 1113 reaches its maximum value (i.e., when the stopper at the slidable end of first guide rod 1114 abuts against first slider 1112 and / or second slider 1113), first guide rod 1114, via its fixed end or stopper, pulls second slider 1113 backward to its initial position. In this initial position, accommodating chamber 1104 is empty, awaiting the insertion of mounting bolt 180 via feed pipe 300. As a preferred embodiment, the ejection power assembly 1110 further includes a second guide rod 1115 and a second buffer spring 11151. One end of the second guide rod 1115 is slidably inserted into the first slider 1112, and the other end is connected to the power unit, which pulls it forward and backward. A raised stopper is provided at the slidable end of the second guide rod 1115. A second buffer spring 11151 is disposed between the power unit and the first slider 1112. The second buffer spring 11151 is in a compressed state and serves to provide a buffer between the power unit and the first slider 1112.

[0077] Of course, in other embodiments, the displacement of the clamp 110 and the push rod 111 can also be achieved through other existing methods. For example, the clamp 110 and the push rod 111 can be pushed forward by cylinders respectively, and the time and sequence of pushing the displacement of the two can be set; for example, the clamp 110 and the push rod 111 can be pushed forward by an electric push rod, or the clamp 110 and the push rod 111 can be pushed forward by a worm gear structure push rod driven by a motor, etc.

[0078] As a preferred solution, the automatic clamping equipment for anodized titanium alloy bolt surface treatment workpieces provided in this embodiment also includes a support block 130, which is arranged on the opposite side of the clamping spring 150 from the ejector, and provides support force for the clamping spring 150 in the clamping operation by abutting against it; the height of the ejector is configured to be higher than the ejector, avoiding the position when the clamped clamping bolt 180 is rotated to this side; the support block 130 can approach or move away from the clamping spring 150. Furthermore, the side of the support block 130 facing the clamping spring 150 is concave, and the concave surface is adapted to the size of the clamping spring 150, so as to simultaneously serve as a circumferential limit for the clamping spring 150.

[0079] As a preferred embodiment, the automatic clamping device for anodized titanium alloy bolt surface treatment workpieces provided in this embodiment also includes an expansion clamp 120. This expansion clamp 120 is positioned upstream of the ejector's loading position on the spiral line and comprises two openable and closable jaws. By opening and closing these jaws, the expansion clamp 120 can open the spring gap of the clamping spring 150 at the loading position, facilitating easier insertion of the clamping bolt 180 protruding from the clamp 110 into the gap of the clamping spring 150. Notably, after the expansion clamp 120 is opened, the gap in the clamping spring 150 is still smaller than the diameter of the clamping bolt 180, and after closing, the thickness of the front end of the expansion clamp 120 is smaller than the gap in the clamping spring 150. The expansion clamp 120 opens before the clamping bolt 180 is inserted into the gap of the clamping spring 150 and closes after the clamping bolt 180 is inserted into the gap of the clamping spring 150. Preferably, the two jaws approach and move apart in a parallel manner. Exemplarily, the expansion clamp 120 can be made of a thumb cylinder.

[0080] As a preferred embodiment, the automatic clamping device for anodized titanium alloy bolt surface treatment workpieces provided in this embodiment further includes a spring guide needle 140. The spring guide needle 140 is disposed above the ejector and inserted into the gap of the clamping spring 150 to pre-open the gap of the clamping spring 150 to ensure smooth insertion of the expansion clamp 120. Preferably, the diameter of the spring guide needle 140 is approximately equal to the width of the front end of the expansion clamp 120 in the closed state.

[0081] The automatic clamping equipment for anodizing titanium alloy bolts provided in this embodiment also includes a first bracket 160 and a second bracket 170. The first bracket 160 is fixed to a base surface such as a workbench 400, and the second bracket 170 is fixed to the first bracket 160. The support block 130, expansion clamp 120, and spring guide needle 140 are all disposed on the bottom of the first bracket 160, and the assembly assembly is disposed on the top surface of the first bracket 160. Furthermore, the clamping equipment provided in this embodiment also includes a third bracket for securing the clamping motor 191 and a fourth bracket for securing the sleeve 151.

Specifically, the first bracket 160, the second bracket 170, the third bracket, and the fourth bracket can all be supported by columns. Of course, the first bracket 160, the second bracket 170, the third bracket, and the fourth bracket can also be configured in other supporting shapes as needed.

[0082] In the automatic clamping equipment for anodized titanium alloy bolt surface treatment workpieces provided in this embodiment, the bolt feeder 200 includes a feeding device and a material separation structure 270. In addition, a housing can be attached to the bolt feeder 200. The feeding device of the bolt feeder 200 includes a hopper 220, a rotating hopper 230 disposed on the back of the hopper 220, and a material rail 240 disposed in front of the hopper 220 for conveying the clamping bolts 180. The material separation structure 270 is connected to the end of the material rail 240 and is connected to the feed air pipe 300. The material rail 240 is composed of a parallel double-plate structure. The gap between the two plates is larger than the screw diameter of the clamping bolt 180 and smaller than the cap end diameter of the clamping bolt 180.

[0083] The clamping bolts 180 in the hopper 220 are arranged in sequence in the material rail 240 under the action of the rotating loading hopper 230, transported to the material distribution structure 270 by the material rail 240, and sent one by one into the feeding air pipe 300 by the material distribution structure 270. When the clamp 110 and the ejector rod 111 of the ejector return to the initial position, they are transported to the accommodating cavity 1104 of the clamp 110 through the feeding air pipe 300.

[0084] In this embodiment, the material distribution structure 270 includes a chute 272 and a material distribution slider 273 disposed within the chute 272. The chute 272 is supported at both ends by a support frame 290, and the material distribution slider 273 can slide along the length of the chute 272. A feed port 2721 is defined at the junction of the chute 272 and the material rail 240, and a dropout port 2734 is defined at the junction of the material distribution slider 273 and the feed port 2721. Both the feed port 2721 and the dropout port 2734 have side notches. The clamping bolts 180 conveyed from the material rail 240 can enter the dropout port 2734 through the feed port 2721. For example, the material distribution slider 273 can reciprocate under the action of a material distribution telescopic rod 27321 of a material distribution cylinder 2732 fixed to the outside of the chute 272. Of course, in other embodiments, a linear displacement structure such as an electric push rod can also be used to achieve the displacement of the material distribution slider 273.

[0085] In this embodiment, a connecting hole 310 is defined within the chute 272, which is connected to the feed pipe 300. The connecting hole 310 is located on the moving trajectory of the blanking port 2734. When the blanking port 2734 moves to that location, the connecting hole 310 can connect with the blanking port 2734. The clamping bolt 180 within the blanking port 2734 can drop into the feed pipe 300 through the connecting hole 310. The material-dividing slider 273 also defines an internal air supply hole 2733, which is provided with an air supply pipe 275. When the blanking port 2734 is located at the blanking port 2734, the internal air supply hole 2733 connects with the connecting hole 310 and the feed pipe 300. The clamping bolt 180 within the feed pipe 300 can be pushed to the target position at the end of the feed pipe 300 by the gas input from the internal air supply hole 2733.

[0086] The bolt feeder 200 provided in this embodiment is provided with a connecting hole 310 in the slide 272, and a blanking port 2734 and an internal air pipe 275 in the material dividing slider 273. The connecting hole 310 is connected to the blanking port 2734 and the internal air pipe 275 respectively by the back and forth sliding of the material dividing slider 273 in the slide 272, thereby realizing the alternation of blanking and conveying materials, and the gas pushing of the clamping bolts 180 is realized through the internal air hole 2733, the connecting hole 310 and the feeding air pipe 300, thereby realizing the long-distance conveyance and one-by-one conveyance of the clamping bolts 180.

[0088] The slide plate 274 is provided with a U-shaped retaining hole 2742 above the blanking opening 2734. The retaining hole 2742 and the blanking opening 2734 have openings on the same side. The size of the retaining hole 2742 is smaller than the cap end of the turning bolt, and the cap end of the mounting bolt 180 can be retained on the retaining hole 2742. The cover plate 271 is provided with an avoidance hole 2713 at a position corresponding to the retaining hole 2742 for avoiding the cap end of the mounting bolt 180. The avoidance hole 2713 and the blanking opening 2734 have openings on the same side. In addition, the avoidance hole 2713 extends along the length direction of the slide groove 272 to form an avoidance hole 2712 for limiting the movement trajectory of the mounting bolt 180.

[0089] The cover plate 271 is provided with a guide hole 2711, which extends along the length of the guide groove 2731, and the end of the guide hole 2711 is inclined toward the side away from the blanking opening 2734. The slide plate 274 is provided with a material distribution guide rod 2741, which is inserted into the guide hole 2711 and can slide along the extension direction of the guide hole 2711.

[0090] When the material distribution slider 273 moves toward the side of the connecting hole 310, the slide plate 274 is driven by the material distribution guide rod 2741 to move away from the blanking port 2734, and the clamping bolt 180 moves along the length direction of the slide groove 272 under the limitation of the avoidance hole 2712. When the blanking port 2734 and the connecting hole 310 are connected, the clamping bolt 180 can be disengaged from the clamping port 2742 and fall into the feeding air pipe 300 through the blanking port 2734 and the connecting hole 310, ensuring the output of the clamping bolts 180 one by one.

The clamping bolts 180 that fall into the silo 220 flow into the rotary loading hopper 230 again along the bottom conical surface of the silo 220.

[0092] In this embodiment, a linear vibrator 250 is installed on the material rail 240. Specifically, the linear vibrator 250 is located in the middle section of the material rail 240, outside the material bin 220.

[0094] Furthermore, in this embodiment, a sweeping plate 260 is provided on the upper part of the hopper 220, and the bottom of the sweeping plate 260 is close to the top of the material rail 240, and is adjacent to the clamping bolt 180 that has completely fallen into the material rail 240, that is, the screw enters the material rail 240 and the cap end rests on the top of the material rail 240. The sweeping plate 260 can swing perpendicular to the length direction of the material rail 240 to sweep off the clamping bolt 180 that protrudes due to not completely falling into the material rail 240.

[0095] This embodiment also provides a specific structure for driving the sweeping plate 260 to swing: the sweeping plate 260 is fixed to a swing shaft 261, the swing shaft 261 is inserted into the opposite side walls of the silo 220, and swings back and forth under the drive of the swing device 262; the swing device 262 includes a sweeping motor 263 and a first connecting rod 2621, a second connecting rod 2622, and a third connecting rod 2623. The end of the swing shaft 261 is fixedly connected to one end of the first connecting rod 2621 and fixed to the silo. The main shaft of the sweeping motor 263 of 220 is fixedly connected to one end of the second connecting rod 2622, and the other ends of the first connecting rod 2621 and the second connecting rod 2622 are rotatably connected to the two ends of the third connecting rod 2623 respectively; the sweeping motor 263 drives the second connecting rod 2622 to rotate, driving the second connecting rod 2622 and the connecting end of the second connecting rod 2622 to make circular motion with the main shaft of the sweeping motor 263 as the axis, and drives the connecting end of the third connecting rod 2623 and the first connecting rod 2621 to swing back and forth.

[0096] In other embodiments, a swing motor may be used to drive the swing shaft 261 to rotate back and forth, thereby driving the sweeping plate 260 to swing back and forth. In other embodiments, other structures may also be used, such as hingedly connecting a connecting rod to the sweeping plate 260 at a perpendicular angle, and then connecting the connecting rod with a telescopic structure such as a cylinder, so that the cylinder drives the connecting rod to move back and forth, thereby driving the sweeping plate 260 to swing back and forth.

In other embodiments, the rotating hopper 230 can also be directly driven by a motor located at its center. In other embodiments, the rotation of the rotating hopper 230 can also be achieved by existing mechanisms such as pulleys.

[0098] As a preferred embodiment, multiple shafts are fixed to the back of the hopper 220, each of which is provided with a limiting wheel 234. The limiting wheel 234 is connected to the side of the rack 232 away from the hopper 220. The free end of the limiting wheel 234 is provided with a baffle or block structure to limit the axial position of the limiting wheel 234. The limiting wheel 234 can be driven by the rack 232 to rotate along its axis when the rotating hopper 230 rotates. The limiting wheel 234 can axially limit the rack 232 and the rotating hopper 230. Of course, in other embodiments, the axial limit between the rotating hopper 230 and the hopper 220 can also be achieved through other existing structures.

When the full material proximity switch 280 detects that the pause duration of the clamping bolt 180 on the material rail 240 exceeds a specific value (e.g., 2 seconds), the swing device 262 stops operating. When the full material proximity switch 280 detects that the pause duration of the clamping bolt 180 on the material rail 240 is less than the specific value, the swing device 262 operates normally. This full material proximity switch 280 is conventional technology, and for example, the NR-1705-E2 full material proximity switch 280 purchased from Sitobon can be selected.
