[0002] An electric discharge perforating machine uses a thin copper tube that moves continuously up and down vertically as an electrode to perform pulsed spark discharge on a workpiece, eroding the metal to form small holes.
[0003] In order to ensure the accuracy of electric discharge perforation, a clamping tooling is required to clamp and position the workpiece to avoid loosening. On the other hand, when a row of small holes needs to be processed on the workpiece, a driving mechanism is also required to move the clamping tooling and the workpiece. Therefore, the clamping tooling and the driving mechanism need to be designed and assembled separately, and the clamping work needs to be disassembled and locked during the loading and unloading process, which is cumbersome and needs to be improved. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a follow-up clamping tooling for an electric discharge perforating machine, which realizes the clamping and movement adjustment of the workpiece and improves the simplicity of the loading and unloading operation.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] A follow-up clamping tooling for an electric discharge perforating machine includes: a base, a first sliding seat, a second sliding seat, a spring, a follow-up support rod, a top rod, and a lead screw. The first sliding seat and the second sliding seat are arranged at intervals in the front and back on the base. A first baffle is vertically arranged at the front end of the first sliding seat. A second baffle is arranged on the base in front of the first sliding seat. The follow-up support rod is horizontally arranged at the front end of the first baffle and penetrates forward through the second baffle. The spring is sleeved on the follow-up support rod and is located behind the second baffle. The lead screw is horizontally arranged on the base and passes under the second sliding seat. A nut corresponding to the lead screw is arranged at the bottom of the second sliding seat. The workpiece is arranged on the first sliding seat and abuts against the back of the first baffle.

[0018] The following combines Figures 1 to 2 and further illustrates the technical solution of the present utility model through specific embodiments.
[0019] As Figure 1 shown, a follower clamping tooling for an electric discharge perforator is used for the clamping and lateral movement adjustment of the workpiece 5, and includes: a base 1, a first sliding seat 2, a second sliding seat 3, a spring 10, a follower support rod 11, an ejector rod 15, and a screw rod 16. The first sliding seat 2 and the second sliding seat 3 are arranged at intervals front and rear on the base 1. The screw rod is horizontally arranged on the base and passes under the second sliding seat 3. A nut corresponding to the screw rod 16 is provided at the bottom of the second sliding seat 3, and the rotation of the screw rod 16 drives the lateral movement of the second sliding seat 3.
[0020] In this embodiment, a motor 17 for driving the rotation of the lead screw 16 is provided on the base 1. The motor 17 can be rotationally controlled by a PLC to improve the automation level. As Figure 2 shown, the rotation of the lead screw 16 is driven by the motor 17 to drive the rearward movement of the second sliding seat 3.
[0021] On the base 1, slide rails 21 are provided on both sides of the lead screw 16. A first slider 20 located on the slide rail 21 is provided at the bottom of the first sliding seat 2, and a second slider 19 located on the slide rail 21 is provided at the bottom of the second sliding seat 3. The slide rails 21 improve the smoothness and linearity of the forward and backward lateral movement of the first sliding seat 2 and the second sliding seat 3.
[0022] As Figure 1 shown, a first baffle 6 is vertically provided at the front end of the first sliding seat 2. The workpiece 5 is arranged on the first sliding seat 2 and abuts against the back surface of the first baffle 6. The front end of the workpiece 5 is limited by the first baffle 6. In this embodiment, positioning blocks 7 located on both sides of the workpiece 5 are provided on the back surface of the first baffle 6 to position both sides of the workpiece 5 and improve the positioning accuracy. Screws 8 connected to the first baffle 6 are provided on the positioning blocks 7, which are convenient for disassembly and assembly and facilitate the replacement or longitudinal adjustment of the positioning blocks 7 to adapt to workpieces 5 of different widths.
[0023] On the base 1, a second baffle 4 is provided in front of the first sliding seat 2. The follower support rod 11 is horizontally arranged at the front end of the first baffle 6 and penetrates forward through the second baffle 4. In this embodiment, a guide sleeve 23 corresponding to the follower support rod 11 is provided on the second baffle 4 to guide the lateral movement of the follower support rod 11.
[0024] The spring 10 is sleeved on the follower support rod 11 and is located behind the second baffle 4. In this embodiment, a first external thread 22 located behind the second baffle 4 is provided on the follower support rod 11, and a first nut 9 located at the front end of the spring 10 is provided on the first external thread 22 to adjust the compression of the spring 10. The elastic force of the spring 10 is used to support the rearward movement of the first nut 9, the follower support rod 11, and the first baffle 6.
[0025] As Figure 1 shown, a vertical plate 14 is provided on the second sliding seat 3. The ejector rod 15 is horizontally arranged in the vertical plate 14 and extends forward to the rear end of the workpiece 5. A second external thread is provided on the ejector rod 15, and second nuts 18 located on both sides of the vertical plate 14 are provided on the second external thread to adjust the lateral movement and locking of the ejector rod 15 in the vertical plate 14 to adapt to workpieces 5 of different lengths. The ejector rod 15 moves laterally with the second sliding seat 3 and is driven by the lead screw 16.
[0026] A top plate 13 is vertically arranged at the front end of the ejector rod 15, and a nylon plate 12 is arranged on the front end face of the top plate 13. The nylon plate 12 contacts the rear end of the workpiece 5 to avoid damage to the workpiece 5. As Figure 1 shown, the workpiece 5 is placed on the first slide 2 and limited at the front end by the first baffle 6. The rear end of the workpiece 5 is fixed and the spring 10 is compressed by the ejector rod 15. The first baffle 6 and the ejector rod 15 are used to clamp the workpiece 5, improving the stability of the workpiece 5 during electric discharge drilling.
[0027] As Figure 2 shown, when it is necessary to adjust the hole position of the workpiece 5 by moving it backward, the ejector rod 15 first moves backward a specified distance. At the same time, the first baffle 6 moves backward under the action of the follower support rod 11 and the spring 10. This can not only ensure the clamping of the workpiece 5 but also does not affect the lateral movement adjustment of the workpiece 5, with good follow-up effect. When discharging after processing, as long as the ejector rod 15 moves backward to the maximum stroke to completely release the spring 10 and the first baffle 6 no longer clamps the workpiece 5, the workpiece 5 can be discharged and loaded, improving the simplicity of the loading and unloading operation.
