Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a stamping clamping plate. Background Art

[0002] The stamping clamping plate is an important tool used to fix and clamp the workpiece in the stamping process. The stamping clamping plate can quickly limit the workpiece after stamping, thereby facilitating subsequent rapid transportation and effectively improving the efficiency of workpiece processing.

[0003] However, most of the existing stamping clamping plates are fixed structures, which are not convenient for buffering and protecting the clamped workpiece, thereby reducing the protection performance of the outside of the workpiece when the workpiece is clamped and guided. Therefore, a stamping clamping plate is urgently needed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a stamping clamping plate to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a stamping clamping plate, comprising a connecting base, a servo motor for transmission is arranged near the rear of the inner end surface of the connecting base, and a transmission screw is fixedly arranged at the output end of the servo motor,

[0006] A bidirectional rack, wherein the bidirectional rack is slidably connected to the inner end surface of the connecting base through the transmission screw, and a thread guide groove is provided at the center of the rear end surface of the bidirectional rack;

[0007] A guide device, wherein the guide device is provided with two groups, and the two groups of the guide devices are rotatably clamped on the inner end surface of the connecting base;

[0008] The clamping device is provided with two groups in total, and the clamping devices are elastically slidably clamped at the outer end of the guide device.

[0009] Preferably, the clamping device comprises a clamping card plate, and guide slide shafts are arranged at four corners of the rear end surface of the clamping card plate, and a spring clamp ring is arranged on the outer end surface of the guide slide shaft near the clamping card plate.

[0010] Preferably, the guide device comprises a transmission gear, a connecting arm is provided at the center of the upper end surface of the transmission gear, and a fixed guide seat is provided at the end of the connecting arm.

[0011] Preferably, the clamping plate is slidably engaged with the fixed guide seat through the guide sliding shaft, and the movable part of the spring clamp ring is fixedly connected to the inside of the fixed guide seat. The bottom of the spring clamp ring can move relative to the guide sliding shaft, thereby facilitating the subsequent provision of sufficient buffering elastic force for the clamping plate.

[0012] Preferably, the two sets of transmission gears are meshedly connected with the bidirectional rack, which can facilitate the subsequent clamping of the clamping plate to quickly and stably clamp and limit the workpiece.

[0013] Preferably, the transmission screw is threadedly connected to the bidirectional rack through the threaded guide groove. The threaded connection between the transmission screw and the bidirectional rack can accurately drive the bidirectional rack to move, thereby improving the accuracy of driving the two sets of transmission gears to mesh and rotate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a clamping device and a guiding device. When the workpiece is protectively clamped, the servo motor can drive the two-way rack forward through the transmission screw, so that the two-way rack can mesh with the transmission gear and synchronously drive the two groups of clamping cards to move centripetally to clamp the workpiece. At the same time, the spring clamping ring can synchronously perform elastic buffering when the clamping card is clamped to prevent rigid extrusion between the clamping card and the workpiece in a short time, which not only improves the protectiveness of the clamping card to the workpiece, but also improves the stability of the subsequent clamping and limiting of the workpiece.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides an embodiment: a stamping clamping plate, including a connecting base 6, a servo motor 7 for transmission is arranged near the rear of the inner end surface of the connecting base 6, and a transmission screw 1 is fixedly arranged at the output end of the servo motor 7,

[0024] The guide device 3 is provided with two groups, and both groups of the guide devices 3 are rotatably connected to the inner end surface of the connecting base 6;

[0025] The clamping device 2 is provided with two groups, and the clamping devices 2 are elastically slidably clamped at the outer end of the guide device 3.

[0026] The clamping device 2 comprises a clamping card plate 23 , and guide slide shafts 22 are arranged at four corners of the rear end surface of the clamping card plate 23 , and a spring clamp ring 21 is arranged at the outer end surface of the guide slide shaft 22 near the clamping card plate 23 .

[0027] The guide device 3 comprises a transmission gear 33 . A connecting arm 32 is arranged at the center of the upper end surface of the transmission gear 33 , and a fixed guide seat 31 is arranged at the end of the connecting arm 32 .

[0028] The clamping plate 23 is slidably connected to the fixed guide seat 31 through the guide sliding shaft 22, and the movable part of the spring clamping ring 21 is fixedly connected to the inside of the fixed guide seat 31. The bottom of the spring clamping ring 21 can move relative to the guide sliding shaft 22, thereby facilitating the subsequent provision of sufficient buffering elastic force for the clamping plate 23.

[0029] The two sets of transmission gears 33 are meshedly connected with the bidirectional rack 4, which can facilitate the subsequent clamping clamping plate 23 to quickly and stably clamp and limit the workpiece.

[0030] The transmission screw 1 is threadedly connected to the bidirectional rack 4 through the threaded guide groove 5. The threaded connection between the transmission screw 1 and the bidirectional rack 4 can accurately drive the bidirectional rack 4 to move, thereby improving the accuracy of driving the two sets of transmission gears 33 to mesh and rotate.

[0031] Working principle: Before use, the user can install the device on the external transfer device. When clamping the workpiece to be stamped, the user can guide the transfer device to the bottom of the stamping device through the external control device, and face the stamped workpiece at the same time. At this time, the user can start the servo motor 7, which can drive the transmission screw 1 to rotate. The transmission screw 1 can be connected to the threaded guide groove 5 through the thread, thereby driving the bidirectional rack 4 to move forward inside the connection base 6. The bidirectional rack 4 can be connected to the two sets of transmission gears 33 The engagement of the two groups of connecting arms 32 can synchronously drive the two groups of clamping plates 23 to perform centripetal and centrifugal displacements, so that the connecting arms 32 can synchronously drive the two groups of clamping plates 23 to perform centripetal and centrifugal displacements through the fixed guide seat 31. When clamping the workpiece, the two groups of fixed guide seats 31 can drive the clamping plates 23 to perform centripetal displacement. At the same time, when the clamping plates 23 limit the workpiece, the spring retaining ring 21 can move backward under the buffering of the elastic force, so that the clamping plates 23 can gradually increase the force driven by the fixed guide seat 31 until the workpiece is completely clamped and locked.
