Description

Technical Field

[0001] This utility model relates to the field of multi-hole sheet metal stamping, and in particular to a multi-hole sheet metal stamping positioner. Background Technology

[0002] With the increasing demands for product precision and production efficiency in modern manufacturing, multi-hole sheet metal stamping has become a widely used processing technology, especially in the automotive, electronic equipment, and home appliance industries. Sheet metal parts typically require multiple holes to meet design requirements, such as functions like fixing, connecting, ventilation, or mounting accessories. In this process, the stamping machine plays a crucial role. By providing powerful stamping force, the stamping machine combines the punch and the die to simultaneously punch multiple holes in the sheet metal material. The high precision and high efficiency of the stamping machine ensure that the processing of multiple holes is completed in the same operation, reducing processing time and material waste.

[0003] Existing technologies, such as the utility model patent with publication number CN221133752U, disclose a multi-hole punching device for sheet metal parts. This patent includes a worktable with symmetrically arranged uprights on the upper center of the worktable. Hydraulic rods are mounted on the upper sides of the uprights on their adjacent sides. A crossbar is mounted at the lower output end of each hydraulic rod. A connecting block is mounted below the crossbar, and a fixing block is mounted on one side of the lower side of the connecting block. An electric push rod is mounted above the fixing block, and a stamped steel pipe is mounted below the fixing block. The output end of the electric push rod passes through the fixing block and extends into the inside of the stamped steel pipe. After punching is completed, the output end of the hydraulic rod moves the crossbar upwards, and the stamped steel pipe moves upwards with the crossbar. At this time, the electric push rod is activated, and its output end extends, pushing out from the lower end of the stamped steel pipe. When a disc is inserted into the inside of the stamped steel pipe, the output end of the electric push rod directly pushes the disc out, preventing the disc from adversely affecting the next punching operation.

[0004] In the prior art, when using a stamping machine to punch holes in sheet metal parts, the sheet metal parts are usually placed directly on the placement plate without effective fixation and limiting. Due to the lack of a stable clamping device, the sheet metal parts are easily affected by external factors during the stamping process, such as equipment vibration and uneven stamping pressure, which can cause the sheet metal parts to shift or deviate. This unstable state will directly affect the accuracy of the punching and the processing precision. Utility Model Content

[0005] The purpose of this invention is to address the problem in the existing technology where sheet metal parts are typically placed directly on a placement plate without effective fixation and positioning when using a stamping machine to punch holes. Due to the lack of a stable clamping device, the sheet metal parts are easily affected by external factors during the stamping process, such as equipment vibration and uneven stamping pressure, leading to displacement or offset of the sheet metal parts. This instability directly affects the accuracy of the punching and the processing precision. Therefore, a multi-hole sheet metal stamping positioner is proposed.

[0006] To solve the above technical problems, this utility model provides a multi-hole sheet metal stamping positioner, comprising: a base plate, a connecting frame mounted on the upper surface of the base plate, an electric push rod mounted on the upper surface of the connecting frame, a pressure plate mounted on the output end of the electric push rod, a placement plate mounted on the inner wall of the connecting frame, an adjustment structure provided on the upper surface of the placement plate, the adjustment structure including a fixed frame, the fixed frame and the placement plate being fixedly connected, an auxiliary groove being formed on the inner wall of the fixed frame, and two positioning blocks being slidably connected to the inner wall of the auxiliary groove, the upper surfaces of the two positioning blocks being fixedly connected.

A connecting ring is rotatably connected to one side of the auxiliary frame. Several toothed grooves are opened on the inner wall of the fixed frame, and the toothed grooves mesh with the toothed blocks. A limit plate is fixedly connected to one side of the auxiliary frame.

[0007] The effect achieved by the above components is that the sheet metal parts can be clamped by setting the adjustment structure, which prevents the sheet metal parts from shifting during stamping and drilling, making the sheet metal parts more stable during the stamping and drilling process and improving the processing accuracy.

[0010] Preferably, a soft pad, which is a rubber pad, is fixedly connected to one side of the limiting plate.

[0011] The effect achieved by the above components is that the soft pad can increase the friction of the limiting plate, making the clamping of the sheet metal part by the limiting plate more stable.

[0012] Preferably, a plurality of ball bearings are fixedly connected to both sides of the positioning block, and the ball bearings have a circular cross-section.

[0013] The effect achieved by the above components is that the ball bearings can reduce the friction of the positioning block, thereby making the positioning block move more smoothly in the auxiliary groove.

[0014] Preferably, the side of the pressure plate is provided with an auxiliary structure, which includes two screws. The two screws are rotatably connected to both sides of the pressure plate. The arc surface of the screws is threaded with an insert plate. One end of the screw is fixedly connected to a connecting plate.

The sides of both insert plates are slidably connected to connecting plates. The side of the two connecting plates that is close to each other is fixedly connected to the same auxiliary plate.

[0015] The effect achieved by the above components is that by setting up auxiliary structures, the pressure plate can be prevented from directly contacting the sheet metal parts, thereby preventing wear on the pressure plate.

[0016] Preferably, positioning plates are fixedly connected to both sides of the auxiliary plate, and adjusting plates are slidably connected to the inner walls of the positioning plates. The adjusting plates and pressure plates are fixedly connected.

[0017] The effect achieved by the above components is that the positioning plate and the adjustment plate can position the auxiliary plate, making the position of the auxiliary plate more accurate during the fixing process.

[0018] Preferably, the arc surface of the connecting plate is provided with anti-slip texture, and the anti-slip texture is evenly distributed on the connecting plate.

[0019] The effect achieved by the above components is that the anti-slip texture increases the friction of the connecting plate, preventing the operator's hands from slipping when rotating the connecting plate.

[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 7 includes two screws 71, which are rotatably connected to both sides of the pressure plate 4.

[0034] The working principle of the multi-hole sheet metal stamping positioner provided by this utility model is as follows: By setting the adjustment structure 6, the auxiliary frame 604 is first pulled by the connecting ring 608, so that the auxiliary frame 604 drives the toothed block 605 to disengage from the toothed groove 609 of the fixed frame 601. At this time, the spring 607 and the telescopic rod 606 in the auxiliary frame 604 will drive the connecting block 616 to rotate and retract on the connecting frame 615. Then, the auxiliary frame 604 is moved to drive the positioning block 603 to move in the auxiliary groove 602. While the auxiliary block is moving, it will also drive the limiting plate 610 to move until the two limiting plates 610 clamp the sheet metal part. At this time, the connecting ring 608 is released. When the connecting ring 608 is released, the spring 607 will drive the connecting block 616 to rotate on the connecting frame 615 and cause the auxiliary frame 604 to rotate and retract. 4. Restore the position so that the toothed block 605 on the auxiliary frame 604 is inserted into the toothed groove 609. At this time, the sheet metal parts on the placement plate 5 are clamped. Then, the electric push rod 3 in the connecting frame 2 is activated, which drives the pressure plate 4 to move. The pressure plate 4 punches and drills holes in the sheet metal parts on the placement plate 5. While punching and drilling, the placement plate 5 moves inside the base plate 1 and the connecting frame 2. The fixing block 611 and the limiting rod 612 can support the limiting plate 610, making the movement of the limiting plate 610 more stable. The soft pad 613 can increase the friction of the limiting plate 610, making the clamping of the sheet metal parts by the limiting plate 610 more stable. The ball 614 can reduce the friction of the positioning block 603, thereby making the positioning block 603 move more smoothly in the auxiliary groove 602.

[0035] By setting the auxiliary structure 7, the auxiliary plate 76 is moved first, which drives the connecting plate 75 to move. When the connecting plate 75 moves to the appropriate position, the connecting plate 72 is rotated with the help of the anti-slip texture 79, which causes the connecting plate 72 to drive the screw 71 to rotate. When the screw 71 rotates, it will drive the insert plate 73 to move on the positioning rod 74 until the insert plate 73 is inserted into the interior of the connecting plate 75. At this time, the fixing of the auxiliary plate 76 and the pressure plate 4 is completed. The positioning plate 77 and the adjusting plate 78 can position the auxiliary plate 76, making the position of the auxiliary plate 76 more accurate during the fixing process. The anti-slip texture 79 can increase the friction of the connecting plate 72 and prevent the personnel from slipping their hands when rotating the connecting plate 72.
