Description

Technical Field

[0001] This utility model belongs to the field of tooling clamping technology, specifically relating to a batch clamping tooling. Background Technology

[0002] To improve processing efficiency, people often stack multiple sheets together for batch processing in daily life. However, existing batch clamping fixtures often require cumbersome limiting operations, which negatively impacts the processing efficiency of the sheets.

[0003] A patent with publication number CN219005286U discloses a batch clamping device for sheet metal. The device includes sheet metal components, a first clamping plate, a second clamping plate, a fastening locating pin, a support, a movable abutment block, a screw, and a fixed abutment block. In use, several sheet metal components are stacked between the first and second clamping plates. The first and second clamping plates are slid to clamp the sides of the sheet metal components. The fastening locating pin is then used to fix the first and second clamping plates, thus initially limiting the position of the sheet metal components. Next, the support is moved so that the movable abutment block is aligned with the sheet metal component. The screw is then turned, causing the movable abutment block to move towards the fixed abutment block, thereby completing the clamping and fixing of the sheet metal components.

[0004] However, the above-mentioned method for limiting the plate's perimeter requires manual sliding of the first and second clamping plates to initially clamp the plate, followed by manual rotation of the screw to move the movable abutment block closer to the fixed abutment block for final limiting. The entire process is cumbersome and lacks automation. Furthermore, after sliding the first and second clamping plates, tightening pins are needed to further limit their movement, slowing down the limiting rate of the plate. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a batch clamping fixture.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A batch clamping fixture includes a base plate with two clamping plates slidably mounted on its top. A driving mechanism is provided on the top of the base plate to drive the two clamping plates to slide towards or away from each other. An abutment block is provided between the two clamping plates, slidably mounted on the top of the base plate, with its sliding direction perpendicular to the sliding direction of the clamping plates. Stacked plates are placed on the top of the base plate, within the space enclosed by the base plate, the abutment block, and the two clamping plates. A connecting shaft is rotatably mounted on the inner wall of the base plate, engaging with the driving mechanism. A winding reel is fixedly mounted on the outer surface of the connecting shaft, with a pull rope wound on the reel. One end of the pull rope not connected to the winding reel is fixedly connected to the abutment block. A spring is fixedly mounted between the side of the abutment block away from the pull rope and the base plate, and the side of the abutment block away from the pull rope engages with the plate during transmission.

[0008] Furthermore, the driving mechanism includes a motor, and a first slide groove and a second slide groove are formed on the base plate, which are symmetrically arranged on the inner walls of both sides of the base plate; a first guide rod is fixedly installed in the first slide groove, and a bidirectional lead screw is rotatably installed in the second slide groove, with the output shaft of the motor being coaxially and fixedly connected to one end of the bidirectional lead screw; the two clamping plates are both limited and slidably engaged with the first guide rod, and are also threadedly engaged with the two threaded sections of the bidirectional lead screw.

[0009] Furthermore, a third sliding groove is formed on the top of the base plate, and a second guide rod is fixedly installed in the third sliding groove. The abutment block is slidably installed in the third sliding groove and slides in cooperation with the second guide rod. The spring is sleeved on the outer surface of the second guide rod, with one end of the spring fixedly connected to the abutment block and the other end fixedly connected to the base plate.

[0010] Furthermore, a drive wheel is fixedly sleeved on the outer surface of the bidirectional lead screw, a driven wheel is fixedly sleeved on the outer surface of the connecting shaft, and a belt is sleeved between the drive wheel and the driven wheel for transmission.

[0011] This application has the following beneficial effects:

[0012] The start-up drive mechanism not only drives the two clamping plates to slide towards each other, clamping the left and right sides of the stacked plates, but also releases the pull rope, causing the abutment block to slide towards the stacked plates, thereby clamping the front and rear sides of the stacked plates. The whole operation process is more convenient, without the need for cumbersome operations, with a high degree of automation, improving the processing efficiency of the stacked plates.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a batch clamping fixture includes a base plate 1, two clamping plates 11 are slidably arranged on the top of the base plate 1, and a driving mechanism is provided on the base plate 1 to drive the two clamping plates 11 to slide towards or away from each other.

[0022] The drive mechanism includes a motor 5. A first slide groove 2 and a second slide groove 4 are formed on the base plate 1. The first slide groove 2 and the second slide groove 4 are symmetrically arranged on the inner walls of both sides of the base plate 1, and both the first slide groove 2 and the second slide groove 4 are arranged in a horizontal direction. A first guide rod 3 is fixedly installed in the first slide groove 2. The second slide groove 4 not only has the motor 5 fixedly installed, but also has a bidirectional lead screw 6 rotatably installed. The output shaft of the motor 5 is coaxially and fixedly connected to one end of the bidirectional lead screw 6.

[0023] The two clamping plates 11 are both in a limiting sliding fit with the first guide rod 3 and in a corresponding threaded fit with the two threaded sections of the bidirectional lead screw 6.

[0024] When the motor 5 is started, the output shaft of the first motor 5 drives the bidirectional lead screw 6 to rotate, causing the two clamping plates 11 to slide towards each other along the central axis of the bidirectional lead screw 6. During this process, the clamping plates 11 will also slide relative to the first guide rod 3.

[0025] An abutment block 9 is provided between the two clamping plates 11. A third sliding groove 10 is opened on the top of the base plate 1. A second guide rod 12 is fixedly installed in the third sliding groove 10. The abutment block 9 is slidably installed in the third sliding groove 10 and slides in cooperation with the second guide rod 12. The sliding direction of the abutment block 9 is perpendicular to the sliding direction of the clamping plates 11. Stacked plates 8 are placed on the top of the base plate 1. The plates 8 are located in the space enclosed by the base plate 1, the abutment block 9, and the two clamping plates 11.

[0026] A clearance groove 7 is provided on the base plate 1. A connecting shaft 17 is rotatably arranged in the clearance groove 7 in the horizontal direction. A winding wheel 16 is fixedly sleeved on the outer surface of the connecting shaft 17. A pull rope 18 is wound on the outer surface of the winding wheel 16. The end of the pull rope 18 that is not connected to the winding wheel 16 slides into the third slide groove 10 and is fixedly connected to the abutment block 9.

[0027] The side of the abutment block 9 away from the pull rope 18 is in transmission contact with the plate 8, and a spring 19 is provided between the side of the abutment block 9 away from the pull rope 18 and the base plate 1. The spring 19 is sleeved on the outer surface of the second guide rod 12. One end of the spring 19 is fixedly connected to the abutment block 9, and the other end is fixedly connected to the base plate 1.

[0028] The connecting shaft 17 is engaged with the transmission mechanism. The outer surface of the bidirectional lead screw 6 is fixedly fitted with the driving wheel 13, and the outer surface of the connecting shaft 17 is fixedly fitted with the driven wheel 14. A belt 15 is fitted between the driving wheel 13 and the driven wheel 14 for transmission.

[0029] Working principle: When in use, several plates 8 are stacked between two clamping plates 11, so that the plates 8 are arranged along the sliding direction of the abutment block 9.

[0030] When the motor 5 is started, the output shaft of the motor 5 drives the bidirectional lead screw 6 to rotate, causing the two clamping plates 11 to slide towards each other under the action of the bidirectional lead screw 6, thereby clamping and limiting the left and right sides of the plate 8.

[0031] Meanwhile, the rotation of the bidirectional lead screw 6 also drives the drive wheel 13 to rotate. Under the transmission of the belt 15, the drive wheel 13 drives the connecting shaft 17 to rotate through the driven wheel 14, causing the winding wheel 16 to rotate synchronously. The rotation of the winding wheel 16 will unwind the pull rope 18. Under the elastic action of the spring 19, after the pull rope 18 is unwound, the abutment block 9 will slide towards the plate 8 under the guidance of the third slide groove 10, thereby clamping and limiting the front and rear sides of the plate 8.

[0032] When the plate 8 needs to be removed after processing, the output shaft of the control motor 5 rotates in the opposite direction, the two clamping plates 11 move away from each other and release the restriction on the left and right sides of the plate 8, and the winding wheel 16 will wind up the pull rope 18, so that the abutment block 9 slides away from the plate 8, thereby releasing the restriction on the front and rear sides of the plate 8.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
