Description

Technical Field

[0001] This invention relates to the field of anchor processing technology, and in particular to a double-end face cutting device for anchor processing. Background Technology

[0002] Anchorages are key devices used in prestressed concrete engineering to permanently anchor steel strands, wires, or reinforcing bars. They transfer the tension of prestressing tendons to the concrete structure through post-tensioning. Their application in buildings, bridges, tunnels, and other engineering projects is becoming increasingly widespread. As an important component for fixing and supporting structures, the quality of their processing directly affects the safety and stability of the project.

[0003] During the manufacturing process of anchorages, the end faces need to be machined to the required length. Common machining processes include turning, milling, and grinding. In order to ensure grinding efficiency, some machining operations use a double-end-face vertical CNC grinding machine.

[0004] A double-end vertical CNC grinder is a high-precision machining device that continuously feeds workpieces via a rotating circular feed pan and simultaneously grinds two parallel end faces of the workpiece using two vertically opposed high-speed grinding wheels. Its core working principle is as follows: the workpiece is placed in a hole on the circumference of the feed pan and enters the machining area between the two grinding wheels as the pan rotates. The upper and lower grinding wheels rotate synchronously and perform plunge grinding on the workpiece end faces, thus ensuring extremely high parallelism and dimensional accuracy of the two end faces. The grinding parameters, grinding wheel feed, and compensation actions throughout the entire machining process are precisely controlled by the CNC system.

[0005] Because the anchor workpiece is placed directly in the hole on the feed tray without any fixation, it is prone to shaking during grinding. Combined with gravity, the grinding force on the lower end of the anchor is also greater than that on the upper end, making it difficult to control the machining accuracy (parallelism and flatness) of both ends. Simultaneously, the rigid contact between the workpiece and the hole wall causes rapid wear on the feed tray, rendering the expensive turntable unusable and significantly increasing maintenance costs. Furthermore, this rigid positioning cannot adapt to different anchor models, requiring a new tray to be customized for each production change, resulting in extremely poor flexibility. The workpiece is also prone to accidentally detaching or impacting the edge of the grinding wheel, causing safety accidents and surface scratches, ultimately leading to a comprehensive decline in machining accuracy, equipment lifespan, safety, and overall efficiency. Moreover, the grinding debris scattered on the feed tray requires frequent manual cleaning, further increasing subsequent maintenance costs. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art where the feed tray does not fix the workpiece, resulting in poor control of machining accuracy, affecting the service life of the feed tray, and requiring frequent manual cleaning of debris. Therefore, this invention proposes a double-end face cutting device for anchor machining.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A double-end face cutting device for anchor processing includes a frame. An upper grinding wheel and a lower grinding wheel are respectively provided on the upper and lower parts of the frame. A housing is provided on the frame, and a feeding disc is rotatably connected inside the housing. The feeding disc has several clamps arranged in a circular array. Each clamp includes a circular clamping seat with a circular cavity. Several clamping rods arranged in a circular array are slidably connected within the cavity, and a transmission disc is rotatably connected within the cavity. The transmission disc has several transmission grooves, and transmission pins are fixedly connected to each of the clamping rods. The transmission pins are respectively inserted into the transmission grooves. A pushing assembly is provided outside the transmission disc to drive its rotation. An arc-shaped extrusion member is fixed above the feeding disc outside the frame to extrude the pushing assembly. A fixing mechanism is also provided on the clamps to fix the transmission disc. An air-jet cleaning mechanism is provided on the housing for cleaning the feeding disc and clamps with air jets.

[0009] In some embodiments, the pushing assembly includes a push block fixed to the transmission disk, a pressure rod provided on the outside of the push block, a rotating shaft fixedly connected to the lower part of the pressure rod, the pressure rod being rotatably connected to the push block through the rotating shaft, and a torsion spring connected between the rotating shaft and the push block, and a first roller being rotatably connected to the outer end of the pressure rod.

[0010] In some embodiments, the fixing mechanism includes a slider slidably connected within a push block and a fan-shaped second pressure block fixed to the outer surface of a rotating shaft. One side of the second pressure block has a first abutting surface that abuts against the outer surface of the slider, and the other side has a second abutting surface. A limiting protrusion that abuts against the second abutting surface is fixed to the outer side of the push block, and a clearance groove adapted to the second pressure block is provided on the side of the slider that contacts the first abutting surface. A first pressure block is slidably connected within the slider. One end face of the first pressure block is located within the clearance groove, and the other end face passes through the slider and approaches the outer circular surface of the clamping seat. A first return spring is connected between the slider and the push block.

[0011] In some embodiments, the fixing mechanism further includes a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder is fixed inside one of the clamping rods, and a first piston is slidably connected inside the first hydraulic cylinder. A sliding rod is fixedly connected to the first piston, and one end of the sliding rod extends out of the clamping rod along its length. The second hydraulic cylinder is fixed to the push block, and a second piston is slidably connected inside the second hydraulic cylinder. A push rod connected to the slider is fixedly connected to the second piston. A flexible connecting pipe connects the second hydraulic cylinder and the first hydraulic cylinder. Hydraulic oil is provided in the second hydraulic cylinder between the second piston and the connecting pipe, in the first hydraulic cylinder between the first piston and the connecting pipe, and in the connecting pipe.

[0012] In some embodiments, the outer circular surface of the clamping seat is provided with an arc-shaped through groove, the push block is slidably connected in the through groove, and a collar fixed to the push block is sleeved on the outer circular surface of the clamping seat outside the through groove, and the connecting pipe passes through the collar and the through groove.

[0013] In some embodiments, a reset block is fixedly installed on the outer surface of the collar away from the push block, and a second roller is rotatably connected to the outer end of the reset block. A limit member is fixedly connected to the outer circular surface of the clamping seat on one side of the reset block.

[0014] In some embodiments, the jet cleaning mechanism includes an air cylinder and a jet pipe respectively fixed to the housing. The air cylinder is located on one side of the feeding tray, and the jet pipe is located above the feeding tray and communicates with the air cylinder. The jet pipe is provided with a plurality of jet nozzles.

[0015] In some embodiments, the air cylinder includes a cylinder fixed to a housing and a piston rod slidably connected to the cylinder. An air guide pipe is connected between the cylinder and the air jet pipe. A third piston, fixed to the piston rod, is slidably connected to the cylinder. A push plate is fixedly connected to the outer end of the piston rod. A second return spring is connected between the push plate and the cylinder.

[0016] In some embodiments, a feeding pipe is fixedly connected to the upper part of the housing away from the air cylinder. The feeding pipe is located above the clamping seat, and a connecting plate is connected between two adjacent clamping seats. The upper surface of the connecting plate is flush with the upper surface of the clamping seat. An arc-shaped guide plate is fixedly connected inside the housing between the feeding pipe and the lower grinding wheel. The guide plate is located directly below the clamping seat, and the upper surface of the guide plate is flush with the upper surface of the lower grinding wheel.

[0017] In some embodiments, an inclined feeding trough plate is fixedly connected to the side of the housing near the air cylinder. The feeding trough plate is located below the feeding tray, and one end of the feeding trough plate extends outward from the housing.

[0018] Compared with the prior art, the present invention provides a double-end face cutting device for anchor machining, which has the following advantages:

[0019] 1. Through the coordinated arrangement of the fixture and the extrusion component, before the anchor workpiece enters between the upper and lower grinding wheels, the extrusion component can drive multiple clamping rods in the fixture to automatically clamp and fix the anchor workpiece, thereby preventing the anchor workpiece from shaking during the grinding process. At the same time, it can also overcome the influence of the weight of the anchor workpiece, avoid excessive grinding force on the lower end of the anchor, and thus better ensure the machining accuracy of the upper and lower end faces. In addition, it can also prevent the workpiece from making hard contact with the hole wall, effectively avoid wear of the feed plate, ensure the normal service life of the feed plate, and reduce the maintenance cost in the later stage to a certain extent.

[0020] 2. Through the cooperation of the fixing mechanism and the pressure bar, the fixing mechanism will also be triggered during the process of multiple clamping rods automatically clamping and fixing the anchor workpiece, thereby automatically fixing the transmission plate in the clamping seat, thus achieving the purpose of fixing multiple clamping rods in the clamping seat, ensuring the stability of the anchor workpiece clamping, and thus ensuring the normal operation of the grinding work.

[0021] 3. Furthermore, through the coordinated arrangement of the fixing mechanism and the pressure rod, even for anchor workpieces with other outer diameters, the extrusion component can drive the clamping rod to clamp them. As long as the end of the clamping rod contacts its outer surface, the fixing mechanism can be triggered, causing the pressure rod to deflect at a certain angle to avoid the extrusion component, thereby clamping and fixing the clamping rod. Therefore, it is also possible to clamp and fix anchor workpieces with the same outer diameter, so that the fixture can clamp and fix anchor workpieces with various outer diameters, improving the clamping flexibility and flexibility of the fixture. Therefore, when it is necessary to process anchor workpieces with other outer diameters, the trouble of changing the feeding plate and the fixture is eliminated.

[0022] 4. Through the coordinated design of the air jet cleaning mechanism and the reset block, after the anchor workpiece is removed from between the upper and lower grinding wheels after grinding, the relevant components in the fixture can be automatically reset under the obstruction of the upper push plate of the air jet cleaning mechanism. At the same time, the relevant components in the fixing mechanism will also be automatically reset, and the clamping rod will be separated from the anchor workpiece, thereby achieving the purpose of automatically releasing the anchor workpiece. As a result, the fixture can not only automatically clamp and fix the anchor workpiece, but also automatically release the clamping and fixing after grinding. Both actions are performed automatically without human intervention, which improves its ease of use and also improves the automation level of grinding work.

[0023] 5. Through the coordinated design of the clamp and the air jet cleaning mechanism, when the clamp releases its grip on the anchor workpiece, the workpiece automatically detaches from the clamp. As the feed tray rotates, the reset block on the clamp squeezes the air cylinder, which in turn blows high-pressure air through the air nozzle on the air jet pipe onto the clamp and feed tray below. The high-pressure air effectively blows away the grinding debris, which falls to the bottom of the housing, thus achieving the purpose of automatic cleaning of the clamp and feed tray. This cleaning action can effectively reduce the frequency of manual cleaning, thereby further reducing the later maintenance costs and workload.

[0024] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0052] Reference Figure 1-4 The upper part of the housing 3, away from the air cylinder 901, has a feeding pipe 10 with open ends. A support frame 1001 is fixedly installed on the outside of the feeding pipe 10 and is fixed to the outside of the housing 3. The feeding pipe 10 is located above the clamping seat 601, and the lower opening of the feeding pipe 10 is located on the circumferential movement path of the clamp 6. A connecting plate 16 is connected between two adjacent clamping seats 601. The upper surface of the connecting plate 16 is flush with the upper surface of the clamping seat 601. Inside the housing 3, a horizontally arranged arc-shaped guide plate 18 is fixedly connected between the feeding pipe 10 and the lower grinding wheel 4. The guide plate 18 is located directly below the clamping seat 601, and the upper surface of the guide plate 18 is flush with the upper surface of the lower grinding wheel 4.

[0053] An inclined feeding trough plate 11 is fixedly connected to the side of the housing 3 near the air cylinder 901. The upper end of the feeding trough plate 11 is located on the lower side of the feeding tray 5, and the lower end of the feeding trough plate 11 extends outward from the housing 3.

[0054] A drain outlet is provided on one side of the housing 3. A sludge collection tank 13 is fixedly installed on the outside of the drain outlet, and a drain pipe 14 is fixedly installed on the lower part of the sludge collection tank 13.

[0055] Both the upper and lower parts of the frame 1 are equipped with drive mechanisms 12. The drive mechanism 12 includes a second motor fixedly installed on the back of the frame 1 and a drive wheel and a driven wheel respectively rotatably installed on the frame 1. A transmission belt connects the drive wheel and the driven wheel. The driven wheel in the upper drive mechanism 12 is fixed to the upper main shaft 201, and the driven wheel in the lower drive mechanism 12 is fixed to the lower main shaft 401 (the specific structure of the drive mechanism 12 is not shown in the drawing).

[0056] In this invention, in the initial state, the clamp 6 and the fixing mechanism 8 are specifically as follows: Figure 7-11As shown, during the grinding operation, a certain number of anchor workpieces 17 are first loaded into the feed tube 10 through the upper opening. At this time, the anchor workpieces 17 are stacked in the feed tube 10, and the bottom anchor workpiece 17 just falls on the upper surface of the clamp 6 or the connecting plate 16. Then, the second motor in the drive mechanism 12 is started, which drives the upper grinding wheel 2 and the lower grinding wheel 4 to rotate. Simultaneously, the first motor 15 is started. At this time, the first motor 15 drives the feeding disc 5 to rotate slowly clockwise inside the housing 3 via the transmission shaft 501. During this process, the feeding disc 5 can drive one of the clamps 6 in its initial state to approach the lower end of the feeding tube 10 until the inner hole of the annular clamping seat 601 moves to the lowest anchor workpiece 17. Under the action of gravity, the anchor workpiece 17 falls into the inner hole of the clamping seat 601. At this time, the lower surface of the anchor workpiece 17 falls on the upper surface of the guide plate 18, and the upper surface of the anchor workpiece 17 is also higher than the upper surface of the clamping seat 601. As the feeding disc 5 continues to rotate, the clamp 6 can drive the anchor workpiece 17 to move closer to the upper grinding wheel 2 and the lower grinding wheel 4. When the next clamp 6 moves to the lower end of the feeding tube 10, similarly, the lowest anchor workpiece 17 will also fall into the inner hole of the clamping seat 601 below, thus achieving the purpose of automatic feeding.

[0057] Then, the anchor workpiece 17 continues to move with the clamping seat 601 until the first roller 6010 outside the clamping seat 601 contacts the end of the pressing member 7. The pressing member 7 will then restrict the first roller 6010 to a certain extent. As the clamping seat 601 continues to move, and under the restriction of the first roller 6010 by the pressing member 7, the first roller 6010, the push block 608, the collar 6012, and the reset block 6013 can move around the axis of the clamping seat 601. A relative deflection occurs on 01, causing the reset block 6013 to separate from the limiting member 6015. The push block 608 can then drive the transmission disk 606 to rotate synchronously relative to the clamping seat 601. During this process, the transmission disk 606 can push the transmission pin 605 and the clamping rod 604 to slide on the guide rail 603 towards the axis of the clamping seat 601 through the transmission groove 607 until the clamping rod 604 contacts the outer circular surface of the anchor workpiece 17. The six clamping rods 604 can then clamp the anchor workpiece 17.

[0058] Furthermore, during the sliding process of the clamping rod 604 towards the anchor workpiece 17, the sliding rod 802 will first contact the outer circular surface of the anchor workpiece 17. Therefore, as the clamping rod 604 continues to slide, the sliding rod 802 will stop sliding, while the first hydraulic cylinder 801 will continue to move with the clamping rod 604, thereby enabling the first piston 803 to slide relative to the first hydraulic cylinder 801. During this process, the first piston 803 can drive the second piston 807 to slide in the second hydraulic cylinder 805 through hydraulic oil. The second piston 807 then directly pushes the slider 808 to slide in the push block 608 through the push rod 806, and compresses the first return spring 8010 to a certain extent. Until the clamping rod 604 contacts the outer circular surface of the anchor workpiece 17, the clearance groove 8081 on the slider 808 also slides to the second pressure block 8011. Due to the sliding of the slider 808, the area where the slider 808 originally contacted the first abutment surface 8012 will separate from the first abutment surface 8012, and the clearance groove 8081 will align with the first abutment surface 8012 on the second pressure block 8011. At this time, as the feeding disc 5 continues to move, the extruder 7 can push the pressure rod 609 and the rotating shaft 6091 to rotate around the connecting pin 6081 by a certain angle through the first roller 6010, while simultaneously compressing the torsion spring 6092 to a certain extent. Specifically, as shown... Figure 4 , Figure 12 and Figure 13 As shown. During this process, the second pressure block 8011 will also deflect into the clearance groove 8081 along with the rotating shaft 6091, and squeeze one end face of the first pressure block 809, so that the first pressure block 809 slides on the slider 808 towards the outer circular surface of the clamping seat 601, thereby pressing the first pressure block 809 onto the outer circular surface of the clamping seat 601, thereby fixing the push block 608 to the outer surface of the clamping seat 601, and then fixing the transmission disk 606 and each clamping rod 604 on the clamping seat 601. At this time, each clamping rod 604 can clamp and fix the anchor workpiece 17 in the clamping seat 601, which can effectively prevent the anchor workpiece 17 from shaking during the grinding process, and ensure the processing quality and processing accuracy.

[0059] As can be seen from the above, after each clamping rod 604 contacts and clamps the anchor workpiece 17, the corresponding component in the fixing mechanism 8 can be triggered by the sliding rod 802, and the slider 808 will eventually slide until the avoidance groove 8081 is aligned with the first abutment surface 8012, thereby releasing the locking between the pressure rod 609 and the rotating shaft 6091 and the push block 608. As the feeding plate 5 continues to rotate, the extrusion member 7 can push the pressure rod 609 to deflect, thereby making the pressure rod 609 make an action to avoid the extrusion member 7. This not only avoids collision, but also allows the second pressure block 8011 to squeeze the first pressure block 809, so that the first pressure block 809 automatically presses tightly on the outer circle surface of the clamping seat 601. Even when clamping anchor workpieces 17 with different outer diameters, the above-mentioned avoidance action can be achieved. It is precisely because of this that the clamp 6 can clamp and fix anchor workpieces 17 with more outer diameters, making it more flexible.

[0060] As the feeding disc 5 continues to rotate, the clamped anchor workpiece 17 can be fed into the grinding area between the upper grinding wheel 2 and the lower grinding wheel 4 by the clamp 6. With the high-speed rotation of the upper grinding wheel 2 and the lower grinding wheel 4, the upper and lower end faces of the anchor workpiece 17 can be ground. During this process, the first roller 6010 will always be in contact with the outer surface of the extrusion part 7, so the anchor workpiece 17 will always remain fixed.

[0061] After grinding is completed, the feed plate 5 moves the anchor workpiece 17 out of the grinding area through the clamp 6, and the first roller 6010 will also separate from the extrusion part 7. At this time, under the rebound force of the torsion spring 6092, the pressure rod 609, the rotating shaft 6091 and the second pressure block 8011 are pushed to rotate back to the initial position until the second abutment surface 8013 on the second pressure block 8011 contacts the limiting protrusion 6082, and the reset is completed.

[0062] As the feeding disc 5 continues to rotate, the reset block 6013 and the second roller 6014 installed outside the collar 6012 will both come into contact with the push plate 9014. Then the reset block 6013 and the second roller 6014 will be blocked, and as the feeding disc 5 rotates, the reset block 6013 and the second roller 6014 will drive the collar 6012 to rotate and reset to the initial state, thereby driving the push block 608, transmission disc 606, transmission pin 605 and each clamping rod 604 to reset to the initial state, so as to facilitate the clamping work of the next cycle. At this time, the reset block 6013 will come into contact with the limiting member 6015, and the ground anchor workpiece 17 will fall onto the unloading trough plate 11 under the action of gravity and slide out of the box 3 along the unloading trough plate 11. Furthermore, during this process, the rebound force of the first return spring 8010 can push each component in the fixing mechanism 8 back to its initial state, so as to facilitate the fixing of the next cycle. This cycle repeats to assist the normal operation of the grinding work.

[0063] Then, as the feed pan 5 continues to rotate, the reset block 6013 and the second roller 6014 will no longer deflect with the collar 6012 due to the limitation of the limiting member 6015. At this time, the reset block 6013 and the second roller 6014 will push the push plate 9014 downward, thereby pushing the piston rod 9012 and the third piston 9013 to slide inside the cylinder 9011, while compressing the second reset spring 9015. During the sliding of the third piston 9013, high-pressure gas can be injected into the jet pipe 902 through the air guide pipe 903, and finally sprayed onto the lower clamp 6 and feed pan 5 through the jet nozzle 9021, thereby blowing the grinding debris into the housing 3, and finally into the sludge collection tank 13 along with the grinding fluid and discharged through the drain pipe 14, thereby achieving the purpose of automatically cleaning the clamp 6 and feed pan 5. Furthermore, after the clamp 6 rotates at a certain angle with the feed tray 5, the reset block 6013 and the second roller 6014 will separate from the push plate 9014. Then, under the rebound force of the second reset spring 9015, the components inside the air cylinder 901 can be reset so as to facilitate the next automatic cleaning.

[0064] After being cleaned, the fixture 6 is fed to the feed pipe 10 by the feed tray 5, and the above action is repeated after receiving the next anchor workpiece 17.
