Description
Technical Field
[0001] The present application relates to the technical field of positioning devices, and in particular to a punching positioning device. Background Art
[0002] A punch press, also known as a stamping press, is mainly used to deform a workpiece placed on the punch press so as to form the workpiece into a desired shape. At present, when processing plates, strips and pipes, the workpiece is generally stamped and formed by a punch press.
[0003] A punch press generally includes a workbench, a lower die and a punching block. When a workpiece is punched, the workpiece is generally placed on the lower die on the workbench, and the workpiece placed on the lower die is punched by the punching block on the punch press to deform the workpiece.
[0004] At present, when placing the workpiece on the lower die, it is generally done by the staff directly placing the workpiece on the lower die. When the batch of workpieces placed by the staff is too large, the staff is prone to fatigue, and it is difficult to accurately place the workpiece in the set position. At this time, when the workpiece is stamped, there is a possibility that the processing quality of the workpiece is poor due to the deviation of the workpiece placement position. Utility Model Content
[0005] In order to facilitate placing a workpiece at a set processing position, the present application provides a punching positioning device for a punch press.
[0006] The present application provides a punching positioning device that adopts the following technical solution:
[0007] A punching positioning device, comprising
[0008] Workbench;
[0009] A placement seat, the placement seat comprising a mounting plate arranged on the top of the workbench and two bases arranged oppositely on the top of the mounting plate, a placement groove is provided on one side of the two bases close to each other, and each placement groove runs through both ends of the base;
[0010] The adjusting assembly is provided with two adjusting assemblies, and the two adjusting assemblies correspond to the two bases one by one. Each adjusting assembly includes a transverse adjusting part and a longitudinal adjusting part, and the transverse adjusting part and the longitudinal adjusting part cooperate with each other to position and clamp the workpiece.
[0011] By adopting the above technical solution, before placing the workpiece, the position between the transverse adjustment part and the longitudinal adjustment part is pre-adjusted according to the position where the workpiece needs to be placed. When placing the workpiece inside the placement groove, the workpiece is placed between the transverse adjustment part and the longitudinal adjustment part, and the transverse adjustment part and the longitudinal adjustment part cooperate with each other to position and clamp the workpiece, so as to facilitate the placement of the workpiece at the set position and improve the processing quality of the workpiece. At the same time, since the positions of the transverse adjustment part and the longitudinal adjustment part are adjustable, the adaptability to workpieces of different sizes is improved.

[0013] By adopting the above technical solution, when placing the workpiece, the workpiece is placed above the lifting plate, and the workpiece is supported by the lifting plate. When the workpiece is stamped, the workpiece drives the lifting plate to move vertically downward, and the lifting spring is compressed by the lifting plate. After the workpiece is stamped, the lifting plate moves vertically upward again under the elastic force of the lifting spring. At this time, the lifting plate applies a vertical upward thrust to the workpiece, thereby facilitating demoulding of the workpiece and improving the convenience of removing the workpiece.
[0014] Optionally, the transverse adjustment portion includes a transverse plate slidably arranged inside the placement groove and a transverse adjustment member arranged on the transverse plate, the length direction of the transverse plate is consistent with the length direction of the placement groove, and the transverse adjustment member is used to move the transverse plate inside the placement groove.

When placing the workpiece, the transverse plate contacts the workpiece to position the workpiece, thereby improving the accuracy of the workpiece placement position.
[0016] Optionally, the transverse adjustment member includes a transverse adjustment rod spirally penetrated through the inner wall of the base and a transverse adjustment plate arranged at one end of the transverse adjustment rod, and the other end of the adjustment rod is rotatably matched with the transverse plate.
[0017] By adopting the above technical solution, when the transverse plate needs to be moved, the transverse plate and the placement slot are slidably matched, and the transverse adjustment rod and the transverse plate are rotationally matched. Therefore, when the transverse adjustment rod is rotated, the transverse plate moves inside the placement slot, thereby improving the convenience of moving the transverse plate.
[0018] Optionally, the transverse adjustment member further includes a guide rod slidably penetrating the inner side wall of the base, and the guide rod is connected to the transverse plate.
[0019] By adopting the above technical solution, the guide rod slides through the inner wall of the placement groove, and the guide rod and the transverse adjustment rod cooperate with each other to limit the transverse plate, thereby improving the stability of the transverse adjustment rod moving inside the placement groove.
[0020] Optionally, scale marks are provided on the transverse adjustment disk.

[0022] Optionally, an indicator mark is provided at one end of the guide rod close to the lateral adjustment disk.
[0023] By adopting the above technical solution, when the staff rotates the adjustment disk, the staff refers to the indicator mark to rotate it, thereby further improving the convenience of adjusting the position of the transverse plate.
[0024] Optionally, the lifting assembly further comprises a lifting rod vertically arranged at the bottom of the lifting plate, and the bottom end of the lifting rod is slidably penetrated through the bottom of the inner wall of the placement groove.
[0025] By adopting the above technical solution, since the bottom end of the lifting rod slides through the bottom of the inner wall of the placement groove, the lifting rod guides and limits the lifting plate, thereby improving the working stability of the lifting rod.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. Before placing the workpiece, pre-adjust the position between the transverse adjustment part and the longitudinal adjustment part according to the position where the workpiece needs to be placed. When placing the workpiece inside the placement slot, place the workpiece between the transverse adjustment part and the longitudinal adjustment part, and position and clamp the workpiece through the cooperation between the transverse adjustment part and the longitudinal adjustment part, so as to facilitate the placement of the workpiece at the set position and improve the processing quality of the workpiece. At the same time, since the position of the transverse adjustment part and the longitudinal adjustment part can be adjusted, the adaptability to workpieces of different sizes is improved.
[0028] 2. When placing the workpiece, place it above the lift plate and support the workpiece through the lift plate. When stamping the workpiece, the workpiece drives the lift plate to move vertically downward, and the lift spring is compressed through the lift plate. After the workpiece is stamped, the lift plate moves vertically upward again under the elastic force of the lift spring. At this time, the lift plate applies a vertical upward thrust to the workpiece, thereby facilitating demoulding of the workpiece and improving the convenience of removing the workpiece.
