Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a lateral clamping fixture that facilitates workpiece processing. Background Technology

[0002] Fixtures, also known as clamps, are crucial auxiliary tools in machining, product manufacturing, and other production processes, playing an indispensable role in fixing workpieces. They come in a wide variety of types, including welding fixtures, assembly fixtures, and machine tool fixtures, and are widely used in various industrial production scenarios to ensure the positional accuracy and stability of workpieces during processing.

[0003] Currently, most clamping fixtures on the market adopt a horizontal structure design. This structure demonstrates good applicability when horizontally clamping and fixing conventional workpieces, meeting the needs of most horizontal machining operations. However, when faced with some special workpieces, such as long shaft-type workpieces that require vertical fixing, the limitations of horizontal clamping fixtures become apparent. Due to their slender shape, long shaft-type workpieces are difficult for horizontal clamping fixtures to effectively and stably clamp during vertical clamping. On the one hand, the contact area and contact method between the fixture and the long shaft-type workpiece are limited, leading to clamping difficulties and making it difficult to ensure that the workpiece is firmly fixed in the predetermined position. On the other hand, horizontal clamping fixtures provide insufficient lateral support to long shaft-type workpieces when vertically clamping them. During machining, long shaft-type workpieces are easily subject to external forces, such as cutting forces and vibrations, causing them to wobble and shift, resulting in frequent clamping instability. This clamping instability not only seriously affects machining accuracy and product quality but may also cause safety hazards and reduce machining efficiency. Utility Model Content

[0004] In view of this, it is necessary to provide a lateral clamping fixture that facilitates workpiece processing in order to solve the technical problem of unstable vertical clamping of workpieces in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A lateral clamping fixture for facilitating workpiece processing includes a frame and a lateral clamping device mounted on the frame. The lateral clamping device includes a load-bearing beam, a main drive screw, a clamping drive mechanism, and two lateral clamping mechanisms for clamping the workpiece. The load-bearing beam is laterally fixed to the frame and has a transverse groove. The main drive screw rotatably passes through the groove, parallel to it. One end of the main drive screw has a positive thread, and the other end has a reverse thread. The two lateral clamping mechanisms... The two lateral clamping mechanisms are positioned on the same side of the supporting crossbeam and inserted into the slide groove facing each other. They are threadedly connected to both ends of the main drive screw to form a lateral clamping channel on one side of the supporting crossbeam. The clamping drive is mounted on the supporting crossbeam and is shaft-connected to one end of the main drive screw. The clamping drive can drive the main drive screw to rotate, and the main drive screw pushes the two lateral clamping mechanisms to move in opposite or opposite directions along the slide groove, so that the two lateral clamping mechanisms move away from or closer to each other to clamp the workpiece laterally.

[0007] Preferably, each of the two lateral clamping mechanisms includes a clamping frame and a clamping claw. One end of each clamping frame is inserted parallel to the slide groove and is threadedly connected to both ends of the main drive screw. The other ends of each clamping frame extend parallel to the same side of the supporting beam and are perpendicular to the supporting beam. The two clamping claws are respectively located at the ends of the two clamping frames away from the main drive screw and face each other, forming a lateral clamping channel on one side of the supporting beam. The clamping drive drives the main drive screw to rotate, which can push the two clamping frames to move in opposite directions or back to back along the slide groove, so that the two clamping claws move away from or closer to each other.

[0008] Preferably, each of the two lateral clamping mechanisms includes a clamping frame and two clamping claws. The two clamping frames are respectively inserted parallel to each other in the slide groove and are threadedly connected to both ends of the main drive screw. The two ends of the two clamping frames extend parallel to both sides of the supporting crossbeam. The two clamping frames are parallel to each other and perpendicular to the supporting crossbeam, and the two ends of the two clamping frames are symmetrical to each other. Four clamping claws are respectively arranged at the ends of the two clamping frames away from the main drive screw. The clamping claws at both ends of one clamping frame are directly opposite to the clamping claws at both ends of the other clamping frame, so as to form lateral clamping channels on both sides of the supporting crossbeam. The clamping drive drives the main drive screw to rotate, which can push the two clamping frames to move in opposite or opposite directions along the slide groove, so that the clamping claws on the two clamping frames move away from or closer to each other.

[0009] Preferably, each clamping claw includes a main claw and a secondary claw. A vertically arranged spacing adjustment groove is provided at the end of each clamping frame away from the main drive screw. A rotatable secondary drive screw is vertically arranged in each spacing adjustment groove. The upper end of the secondary drive screw has a positive thread, and its lower end has a reverse thread. The main claw and secondary claw are inserted into the spacing adjustment groove, one above the other, and are threadedly connected to both ends of the secondary drive screw. The main claws at the same end of the two clamping frames face each other, and the secondary claws at the same end of the two clamping frames face each other. A spacing adjustment drive connected to the shaft of the secondary drive screw is provided at the upper end of each spacing adjustment groove. The spacing adjustment drive drives the secondary drive screws at the same end of the two clamping frames to rotate, so that the main claws and secondary claws of the clamping claws on the two clamping frames move away from or closer to each other, thereby adjusting the spacing between the main claws and secondary claws of the clamping claws.

[0010] Preferably, each of the main and auxiliary claws is provided with an anti-slip pad on its clamping surface.

[0011] Preferably, the frame includes a base arranged in parallel, two support frames, two lifting sleeves, and two lifting drives. The two support frames are vertically arranged on both sides of the upper end of the base and are symmetrical to each other. The two lifting sleeves are respectively fitted onto the two support frames and can slide freely up and down along the two support frames. The load-bearing beam is horizontally arranged between the two lifting sleeves, and both ends of the load-bearing beam are fixedly connected to the two lifting sleeves. The two lifting drives are vertically arranged on both sides of the upper end of the base, and the driving ends of the two lifting drives are respectively connected to the lower ends of the two lifting sleeves. The two lifting drives move up and down synchronously, which can drive the two lifting sleeves to slide freely up and down along the two support frames synchronously to raise and lower the load-bearing beam.

[0012] Preferably, a protective pad is provided on the upper surface of the base facing the clamping channel.

[0013] Preferably, rollers are provided at the four corners of the lower end of the base.

[0014] Preferably, the lifting drive is a hydraulic cylinder or a worm gear screw jack.

[0015] Preferably, auxiliary storage boxes for storing tools are provided on both sides of the lifting slide.

[0016] As can be seen from the above technical solution, the lateral clamping fixture for facilitating workpiece processing provided in this application includes a frame and a lateral clamping device mounted on the frame. The lateral clamping device includes a load-bearing beam, a main drive screw, a clamping drive, and two lateral clamping mechanisms for clamping workpieces. The load-bearing beam is horizontally fixed on the frame, and a sliding groove is horizontally provided on the load-bearing beam. The main drive screw is rotatably and horizontally inserted into the sliding groove, parallel to the sliding groove. One end of the main drive screw has a positive thread, and the other end has a reverse thread. The two lateral clamping mechanisms are arranged opposite each other on the same side of the load-bearing beam. The two lateral clamping mechanisms are inserted opposite each other into the slide groove and are threadedly connected to both ends of the main drive screw to form a lateral clamping channel on one side of the supporting beam. The clamping drive is set on the supporting beam and drives the main drive screw to rotate. Its beneficial effects are: the main drive screw can drive the two lateral clamping mechanisms to move in opposite directions along the slide groove, forming a clamping force with each other. It can laterally clamp long shaft-type workpieces that need to be vertically fixed. The lateral clamping can provide effective lateral support force for the workpiece, which can improve the stability of the vertical clamping of the workpiece, so as to facilitate the processing of the workpiece and improve the processing efficiency.

Detailed Implementation

[0024] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Please refer to Figure 1 This utility model provides a lateral clamping fixture for easy workpiece processing, including a frame 10 and a lateral clamping device 20 mounted on the frame 10. The lateral clamping device 20 includes a supporting beam 21, a main drive screw 22, a clamping drive 23, and two lateral clamping mechanisms 24 for clamping workpieces. The supporting beam 21 is horizontally fixed on the frame 10, and a sliding groove 25 is horizontally provided on the supporting beam 21. The main drive screw 22 is rotatably and horizontally inserted into the sliding groove 25, parallel to the sliding groove 25. One end of the main drive screw 22 has a positive thread, and the other end has a reverse thread. The two lateral clamping mechanisms 24 are arranged opposite each other on the same side of the supporting beam 21. The clamping mechanism 24 is inserted into the slide groove 25 and is threadedly connected to both ends of the main drive screw 22 to form a lateral clamping channel on one side of the supporting beam 21. The clamping drive 23 is a servo motor, which is installed on the supporting beam 21 and is connected to one end of the main drive screw 22. It is used to drive the main drive screw 22 to rotate in the forward or reverse direction. The main drive screw 22 pushes the two lateral clamping mechanisms 24 to move in opposite or opposite directions along the slide groove 25 so that the two lateral clamping mechanisms 24 move away from each other or closer to each other. When the main drive screw 22 pushes the two lateral clamping mechanisms 24 to move in opposite directions along the slide groove 25, the two lateral clamping mechanisms 24 can form a clamping force with each other and clamp the workpiece to be processed on both sides.

[0026] Please refer to Figure 1 and Figure 3Specifically, each of the two lateral clamping mechanisms 24 includes a clamping frame 241 and a clamping claw 242. One end of each clamping frame 241 is inserted parallel to the slide groove 25 and is threadedly connected to the positive and negative thread ends of the main drive screw 22, respectively. The other ends of each clamping frame 241 extend parallel to the same side of the supporting beam 21 and are perpendicular to the supporting beam 21. The two clamping claws 242 are respectively located on the opposite side of the ends of the two clamping frames 241 away from the main drive screw 22 and face each other. The clamping claws 242 on the two clamping frames 241 are positioned between each other on the supporting beam 21. A lateral clamping channel is formed on one side. When the clamping drive 23 drives the main drive screw 22 to rotate in the forward or reverse direction, it can push the two clamping frames 241 to move in opposite directions or back directions along the slide groove 25, so that the two clamping claws 242 move away from each other or closer to each other. When this lateral clamping fixture is in use, the long shaft-type workpiece to be processed can be erected between the two clamping claws 242. By controlling the clamping drive 23 to drive the main drive screw 22 to rotate, the main drive screw 22 pushes the two clamping frames 241 to move in opposite directions, so that the two clamping claws 242 clamp the two sides of the long shaft-type workpiece in opposite directions and fix it. After the two gripping jaws 242 clamp the workpiece, the gripping drive 23 stops operating. The main drive screw 22 utilizes the characteristic that the reverse rotation of its helical pair cannot transmit power, as well as the effect of friction, to prevent the helical pair from rotating in reverse, thereby achieving self-locking. After the workpiece is processed, the gripping drive 23 rotates in reverse, and through the main drive screw 22, it pushes the two gripping frames 241 to move in opposite directions, releasing the gripping of the workpiece.

[0027] Please continue reading. Figure 3Furthermore, each of the clamping claws 242 includes a main claw 2421 and a secondary claw 2422. Vertically arranged at the ends of the two clamping frames 241 away from the main drive screw 22 are gap adjustment slots 243. A rotatable secondary drive screw 244 is vertically arranged in each gap adjustment slot 243. The upper end of the secondary drive screw 244 has a positive thread, and its lower end has a reverse thread. The main claw 2421 and the secondary claw 2422 are inserted into the gap adjustment slots 2422 in an upper-lower configuration. 3. The screws are threaded to the positive and negative threads of the auxiliary drive screw 244, respectively. Two main jaws 2421 at the same end of the two clamping frames 241 face each other, and two auxiliary jaws 2422 at the same end of the two clamping frames 241 face each other. The clamping surfaces of the main jaws 2421 and auxiliary jaws 2422 are bent in opposite directions, creating a concave structure. At the upper end of each spacing adjustment groove 243, a corresponding... The secondary drive screw 244 is connected to a spacing adjustment drive 245, which is a servo motor. The spacing adjustment drive 245 drives the two secondary drive screws 244 to rotate in the same direction, causing the main jaws 2421 and secondary jaws 2422 on the two clamping frames 241 to move further apart or closer together, thereby adjusting the spacing between the main jaws 2421 and secondary jaws 2422 of the clamping jaws 242. By adjusting the spacing between the main jaws 2421 and secondary jaws 2422, the lateral clamping fixture can adapt to different... For workpieces of varying heights, clamping and fixing them improves the stability and applicability of the clamping mechanism. For example, when the workpiece being clamped is tall, the distance between the main jaw 2421 and the secondary jaw 2422 can be adjusted to the maximum, making them further apart to increase the clamping height and improve the stability of lateral support. When the workpiece being clamped is short, the distance between the main jaw 2421 and the secondary jaw 2422 can be adjusted to reduce the height of the workpiece being clamped, so that the main jaw 2421 and the secondary jaw 2422 can effectively clamp the two ends of the workpiece.

[0028] Furthermore, each of the main jaws 2421 and the secondary jaws 2422 is provided with an anti-slip pad 246 on its clamping surface. The anti-slip pad 246 is preferably made of rubber or polyethylene material. When clamping the workpiece, the anti-slip pad 246 can increase the friction between the main jaws 2421, the secondary jaws 2422 and the workpiece.

[0029] Please refer to Figure 1 and Figure 2In the above embodiment, the frame 10 includes a base 11 arranged in parallel, two support frames 12, two lifting sleeves 13, and two lifting drives 14. The two support frames 12 are vertically arranged on both sides of the upper end of the base and are symmetrical to each other. The two lifting sleeves 13 are respectively sleeved on the two support frames 12 and can slide freely up and down along the two support frames 12. The bearing beam 21 is horizontally arranged between the two lifting sleeves 13, and the two ends of the bearing beam 21 are respectively fixedly connected to the two lifting sleeves 13. The two lifting drives 14 are vertically arranged on the base 11. On both sides of the upper end, the driving ends of the two lifting drives 14 are respectively connected to the lower ends of the two lifting sleeves 13. The two lifting drives 14 move synchronously on the base 11, and can drive the two lifting sleeves 13 to slide freely up and down along the two support frames 12, so as to lift the load-bearing crossbeam 21. The lifting drive 14 is a hydraulic cylinder or a worm gear screw jack. The height of the lateral clamping device 20 can be adjusted by the lifting drive 14, thereby adjusting the height of the clamped workpiece, improving the flexibility of adjusting the workpiece height, and facilitating the worker's processing operation. In this embodiment, both lifting drives 14 are servo motors. When adjusting the height of the lateral clamping device 20, the two lifting drives 14 need to be controlled by the controller to move synchronously.

[0030] Furthermore, a protective pad 15 is provided on the upper surface of the base 11 facing the clamping channel. The protective pad 15 is preferably made of rubber or polyethylene material, which can improve the protection of the base 11 and prevent the lower end of the clamped workpiece from making hard contact with the base 11.

[0031] Please continue reading. Figure 1 or Figure 2 Furthermore, in order to improve the flexibility of the lateral clamping fixture, rollers 16 are provided at the four corners of the lower end of the base 11. During use, the base 11 can be easily moved. The rollers 16 are preferably universal wheels with locking function. When the base 11 is moved into place, the rollers 16 can be locked by the locking function on the rollers 16.

[0032] Furthermore, auxiliary storage boxes 17 for storing tools are provided on both sides of the lifting sleeve 13. During the use of this lateral clamping fixture, some auxiliary tools are required, such as bolts, fasteners and other components. The auxiliary storage boxes 17 can be used to organize and place these auxiliary tools, making it convenient to store and use tools during the workpiece processing.

[0033] Please refer to Figures 4 to 6Furthermore, in a preferred embodiment, each of the two lateral clamping mechanisms 24 includes a clamping frame 241 and two clamping claws 242. A groove 25 is formed through both sides of the supporting beam 21. The two clamping frames 241 are respectively inserted parallel to each other in the groove 25 and are threadedly connected to both ends of the main drive screw 22. The two ends of the two clamping frames 241 extend parallel to both sides of the supporting beam 21. The two clamping frames 241 are parallel to each other and perpendicular to the supporting beam 21, and the two ends of the two clamping frames 241 are symmetrical. Four clamping claws 242 are respectively disposed at the ends of the two clamping frames 241 away from the main drive screw 22. The clamping claws at both ends of one clamping frame 241 are... The clamping claws 242 at both ends of the other clamping frame 241 face each other to form lateral clamping channels on both sides of the supporting beam 21. The clamping drive 23 drives the main drive screw 22 to rotate, which can push the two clamping frames 241 to move in opposite directions or back directions along the slide groove 25, so that the clamping claws 242 on the two clamping frames 241 move away from each other or closer to each other. In use, two workpieces of the same diameter can be erected in the two clamping channels respectively. By controlling the clamping drive 23 to drive the main drive screw 22 to rotate, the main drive screw 22 pushes the two ends of the two clamping frames 241 to move in opposite directions, so that two workpieces of the same diameter can be clamped and fixed at the same time to improve processing efficiency.

[0034] Please continue reading. Figures 4 to 6Furthermore, in this embodiment, each clamping claw 242 includes a main claw 2421 and a secondary claw 2422. Vertically arranged spacing adjustment slots 243 are provided at the two ends of the two clamping frames 241 away from the main drive screw 22. A rotatable secondary drive screw 244 is vertically arranged in each spacing adjustment slot 243. The upper end of the secondary drive screw 244 has a positive thread, and its lower end has a reverse thread. The main claw 2421 and the secondary claw 2422 are inserted into the spacing adjustment slots 243 in an up-down configuration, and are threadedly connected to the positive thread end and the reverse thread end of the secondary drive screw 244, respectively. The two main claws 2421 located at the same end of the two clamping frames 241 face each other, and the two secondary claws 2422 located at the same end of the two clamping frames 241 face each other. Both ends of the opposing clamping surfaces of the claws 2422 are bent in opposite directions, making the opposing clamping surfaces of the main claw 2421 and the auxiliary claw 2422 concave. At the upper end of each spacing adjustment slot 243, a spacing adjustment drive 245 connected to the shaft of the auxiliary drive screw 244 is provided. The spacing adjustment drives 245 are all servo motors. The two spacing adjustment drives 245 located at the opposite ends of the two clamping frames 241 synchronously drive their corresponding two auxiliary drive screws 244 to rotate in the same direction. The spacing between the main claw 2421 and the auxiliary claw 2422 on the two clamping frames 241 can be adjusted respectively. By adjusting the spacing between the main claw 2421 and the auxiliary claw 2422, the lateral clamping fixture can clamp and fix two workpieces of the same diameter and height or two workpieces of the same diameter but different heights at the same time, improving the stability and applicability of the clamping.
