Description

Technical Field

[0001] This application relates to the field of clamping technology, and in particular to a copper block positioning clamp. Background Technology

[0002] Copper electrodes are essential components for electrical discharge machining (EDM) and are often manufactured by machining copper blocks using CNC machine tools. During the production of copper electrodes, the copper block needs to be placed on a clamping base and pre-positioned before it can be machined by the CNC machine tool.

[0003] The existing clamping base has several fixing screws threaded on its side wall. The fixing screws are evenly distributed around the clamping base, and each side of the clamping base has three fixing screws threaded on it. Before positioning the copper block, the staff puts the copper block on the clamping base, and then fixes the copper block with the fixing screws. After fixing, the staff uses calipers to measure the relative position of the copper block on the clamping base, and adjusts the position of the fixing screws according to the measurement results, thus achieving the positioning of the copper block on the clamping base.

[0004] When the copper block is not positioned accurately, the worker needs to loosen the fixing screws on one side and then tighten the fixing screws on the opposite side. If the positioning is still inaccurate, the worker repeats the above process to achieve the positioning of the copper block. The above positioning process of the copper block is rather cumbersome and needs improvement. Utility Model Content

[0005] To simplify the positioning process of copper blocks and facilitate the processing of copper blocks by workers, this application provides a copper block positioning fixture.

[0006] This application provides a copper block positioning fixture, which adopts the following technical solution:

[0007] A copper block positioning fixture includes a base, a clamping seat fixed above the base, and two clamps slidably disposed on the base. The two clamps are located on opposite sides of the clamping seat, and the distance between the two clamps and the clamping seat is the same. The clamps slide along the length direction of the base, and the clamping seat can fix the copper block in the width direction of the base.

[0008] By adopting the above technical solution, with two grippers positioned on both sides of the clamping base at the same interval, it can be ensured that the copper block is clamped evenly and stably during the clamping process. When the worker clamps the copper block, the worker places the copper block on the upper part of the clamping base, and then the worker controls the grippers to clamp the copper block. At the same time, the worker manipulates the clamping base to fix the copper block in the width direction of the base. At this time, the positioning of the copper block is achieved. This setting simplifies the positioning process of the copper block and makes it easier for the worker to process the copper block.

[0009] Optionally, a gear is fixed to the lower end of the gripper, a rack is provided on the base, the gear meshes with the rack, and a driving component for driving the gear to rotate is also provided on the gripper.

[0010] By adopting the above technical solution, the meshing of the gear and rack ensures the precise movement of the gripper on the base, reduces the possibility of different sliding distances between the two grippers, and increases the accuracy of positioning the copper block.

[0011] Optionally, the base has a sliding cavity inside, the rack is fixed to the inner wall of the sliding cavity, the two gears are located at both ends of the rack, and the rack is arranged along the length direction of the sliding cavity.

[0012] By adopting the above technical solution, the rack is set in the sliding cavity inside the base, which improves the space utilization inside the base and makes the overall structure of the clamp more compact. The two gears slide on the same rack, which also reduces the possibility of the gripper shifting due to the angle deviation when the worker installs the rack.

[0013] Optionally, the base includes a base plate and a fixing seat fixed to the base plate, wherein the lower end of the clamping seat is engaged and fixed to the fixing seat.

[0014] By adopting the above technical solution, the clamping seat is fixed by the fixing seat, which makes the disassembly and installation of the clamping seat on the base plate easier. At the same time, this setting makes the maintenance of the base easier.

[0015] Optionally, the fixing base includes a fixing plate, a plurality of snap-fit ​​blocks fixed on the fixing plate, and a snap-fit ​​rod fixed at the center position of the fixing plate. The height of the snap-fit ​​rod is higher than the height of the snap-fit ​​blocks, and the clamping base is snapped and fixed to the fixing plate through the snap-fit ​​blocks and the snap-fit ​​rod.

[0016] By adopting the above technical solution, the locking block and locking rod provide multiple fixing points for the clamping seat, so that the clamping seat is firmly fixed on the fixed plate, reducing the possibility of the clamping seat shifting or rotating on the fixed plate, and increasing the accuracy of positioning the copper block.

[0017] Optionally, the side wall of the clamping seat is threaded with a plurality of fixing screws, the fixing screws being located in the width direction of the base plate, and the ends of the fixing screws being able to abut against the side wall of the copper block.

[0018] By adopting the above technical solution, after the clamping jaws position the copper block in the length direction of the base plate, the workers fix the copper block with fixing screws, so that the copper block is also positioned in the width direction of the base plate, which facilitates the subsequent processing of the copper block.

[0019] Optionally, the inner wall of the sliding cavity is provided with a bidirectional lead screw, which is arranged along the length direction of the base plate. The two grippers are located at the two ends of the bidirectional lead screw. A balance plate is fixed to the lower end of the grippers. The balance plate is rotatably connected to the bidirectional lead screw. A blocking plate is provided on both sides of the bidirectional lead screw along its length direction. The balance plate is slidably connected to the side wall of the blocking plate. The outer wall of the base plate is provided with a driving element for driving the bidirectional lead screw to rotate.

[0020] By adopting the above technical solution, the bidirectional lead screw is set along the length of the base plate, and the two grippers are located at the two ends of the bidirectional lead screw respectively. This allows the two grippers to move synchronously in opposite directions when the bidirectional lead screw rotates. The two grippers slide the same distance under the action of the bidirectional lead screw. The setting of the balance plate ensures the stability of the grippers during the movement process and reduces the possibility of the grippers shaking due to uneven force.

[0021] Optionally, the fixing plate is detachably fixed to the base plate, and the locking rod is detachably fixed to the fixing plate.

[0022] By adopting the above technical solution, this setting allows both the clamping rod and the fixing plate to be replaced according to the model of the clamping seat, thereby increasing the working range of the positioning fixture and enhancing its functionality.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the worker positions the copper block, the worker places the copper block on the upper end of the clamping seat, then fixes the clamping seat above the base. Next, the worker drives the two jaws to clamp the copper block. After the two jaws position the copper block, the worker fixes the copper block in the width direction of the base through the clamping seat. This setting simplifies the positioning process of the copper block and makes it easier for the worker to process the copper block.

[0025] 2. When the staff installs the clamping seat, they align the lower end of the clamping seat with the locking block and the locking rod, and then install the clamping seat on the fixed plate. This arrangement reduces the possibility of the clamping seat rotating or shifting on the fixed plate. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a copper block positioning fixture.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A copper block positioning fixture includes a base 1, a clamping seat 2 fixedly attached to the base 1, and two grippers 3 slidably connected to the base 1. The two grippers 3 are located on opposite sides of the clamping seat 2. In this embodiment, both grippers 3 and the clamping seat 2 are located along the length of the base 1, and the distances from the two grippers 3 to the base 1 are equal. A sliding cavity 7 is provided inside the base 1, and a rack 5 is fixed to the inner wall of the sliding cavity 7. The rack 5 is arranged along the length of the base 1. A driving member 6 is fixed to the lower end of each of the two grippers 3. The driving member 6 is preferably a motor. A gear 4 is fixedly attached to the rotating shaft of the driving member 6. The gear 4 meshes with the rack 5, and both grippers 3 slide along the length of the rack 5 via the gear 4.

[0035] Reference Figure 1 and Figure 2The base 1 includes a base plate 11 and a fixing seat 12 snapped onto the base plate 11. The fixing seat 12 is used to hold the clamping seat 2. Both ends of the base plate 11 along its length are provided with gripping members. In this embodiment, the gripping members are preferably provided with gripping openings at both ends of the base plate 11, allowing workers to move the base plate 11 through the gripping openings. The fixing seat 12 includes a fixing plate 121 snapped onto the base plate 11, a plurality of snapping blocks 122 snapped onto the fixing plate 121, and a snapping rod 123 snapped onto the center of the fixing plate 121. Preferably, there are four snapping blocks 122, which are spaced equally and located along the length and width of the base plate 11. The fixing plate 121 can also be detachably fixed with height-adjustable parts. The bearing blocks are lower than the snap-fit ​​blocks 122. There are four bearing blocks, which are arranged alternately with the four snap-fit ​​blocks 122. The bottom of the clamping seat 2 abuts against the end of the bearing block. The clamping seat 2 is provided with snap-fit ​​grooves that can snap-fit ​​the snap-fit ​​rod 123 and the snap-fit ​​block. The height of the snap-fit ​​rod 123 is greater than the height of the snap-fit ​​block 122. The end of the snap-fit ​​rod 123 away from the base plate 11 is welded and fixed with a cross snap-fit ​​block. This arrangement reduces the possibility of the clamping seat 2 rotating or shifting on the base plate 11. The side wall of the clamping seat 2 is also threaded with a number of fixing screws 8. Preferably, there are four fixing screws 8. All four fixing screws 8 are located in the width direction of the base plate 11, and the ends of the fixing screws 8 can abut against the side wall of the copper block.

[0036] According to Embodiment 1 of this application, the implementation principle of a copper block positioning fixture is as follows: When the worker positions the copper block, the worker places the copper block above the clamping seat 2, and then the worker controls the two grippers 3 to clamp the copper block through the driving component 6. At this time, the copper block is fixed in the length direction of the base plate 11. Then the worker tightens the fixing screw 8, and under the fixing action of the fixing screw 8, the copper block is fixed to the side wall of the clamping seat 2. At this time, the copper block is fixed in the width direction of the base plate 11. This setting simplifies the positioning process of the copper block and makes it easier for the worker to process the copper block.

[0037] Example 2

[0038] Example 2 differs from Example 1 in that: (Refer to...) Figure 3 and Figure 4A bidirectional lead screw 9 is rotatably connected to the inner wall of the sliding cavity 7. A balance plate 101 is welded and fixed to the ends of both grippers 3. The balance plate 101 is rotatably connected to the bidirectional lead screw 9. The two grippers 3 are located at the two ends of the bidirectional lead screw 9. Two blocking plates 102 are also welded and fixed to the inner wall of the sliding cavity 7. The blocking plates 102 are arranged along the length of the base plate 11, and are located on both sides of the bidirectional lead screw 9. The two ends of the balance plate 101 are slidably connected to the inner walls of the two blocking plates 102. Bolts are also used to secure the balance plate 101 to the outer side of the base plate 11. A drive element 103 is provided. In this embodiment, the drive element 103 is preferably a drive motor. The rotation shaft of the drive element 103 is fixedly engaged with the bidirectional lead screw 9. In addition, the fixed plate 121 is detachably fixed to the base plate 11, and the clamping rod 123 is detachably fixed to the fixed plate 121. When the model of the copper block changes, so that the model of the clamping seat 2 also needs to be changed, the operator can disassemble the fixed plate 121 and the clamping rod 123 and replace them with new fixed plate 121 and clamping rod 123, thereby realizing the clamping of different models of clamping seats 2.

[0039] According to Embodiment 2 of this application, the implementation principle of a copper block positioning fixture is as follows: When the operator positions the copper block, the operator disassembles and replaces the fixed plate 121 and the locking rod 123 according to the model of the clamping seat 2. Then, the clamping seat 2 is locked onto the fixed plate 121. The operator controls the bidirectional lead screw 9 to rotate through the driving element 103. At this time, the bidirectional lead screw 9 drives the balance plate 101 to slide on the side wall of the blocking plate 102. The balance plate 101 drives the jaws 3 to slide. At this time, the two jaws 3 clamp the copper block. This setting makes the sliding distance of the two jaws 3 more balanced, making the positioning process of the copper block more accurate and stable.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
