Description

Technical Field

[0001] This utility model relates to the field of stamping parts processing technology, specifically a stamping parts edge grinding device. Background Technology

[0002] Stamping is one of the most commonly used processing methods in hardware manufacturing. It refers to the process of forming steel / non-ferrous metal sheets into a specified shape by using a mold and a press to provide the required processing pressure under room temperature conditions. Since the edges of some stamped parts are directly extruded and cut off by strong pressure, there will be some burrs and sharp edges, which need to be ground and repaired by grinding equipment.

[0003] Currently, some stamping grinding equipment has relatively fixed motion structures and movements. It can only perform grinding work by getting close to the stamping part according to the movement set by the structure. The movement mode cannot be changed. When dealing with different types of stamping parts, the posture and position of the stamping part itself can only be manually adjusted. The movement mode of the grinding structure cannot be adapted to the stamping part autonomously, and there is still room for improvement in work adaptability. Utility Model Content

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-6 In this embodiment of the present invention, a stamping edge grinding device includes a worktable 1, a moving structure 2, and a grinding structure 3. The worktable 1 includes a work surface 101. There are two sets of moving structures 2, and the bottom ends of the two sets of moving structures 2 are slidably connected to the two sides of the upper surface of the work surface 101. The grinding structure 3 is suspended on one side of the moving structure 2. The grinding structure 3 includes a base plate 304. The bottom of both sides of the base plate 304 is fixedly installed with hanging rods 305. An electric push rod 306 is hinged to the bottom of one side of the base plate 304. The lower ends of the two hanging rods 305 are hinged to both sides of the connecting seat 307. The output end of the electric push rod 306 is hinged to one side of the connecting seat 307.

[0047] Specifically, the stamped part to be polished is placed on the upper surface of the worktable 101. The moving structure 2 carries the polishing structure 3 close to the position of the workpiece to be polished, and the moving polishing work is continuously performed. At the same time, the connecting seat 307 can be controlled to deflect by the retraction of the electric push rod 306 and the hoisting of the lifting rod 305, thereby adjusting the angle of the polishing end of the polishing structure 3 to fit the edge structure of various shapes of different stamped parts, which has extremely high work adaptability. Example 1

[0048] like Figure 2 As shown, in this embodiment, the workbench 1 also includes support legs 102, a linear motor 103, a panel mounting slot 104, and a detachable panel 105. There are four support legs 102, which are fixedly installed at the four corners of the bottom side of the workbench 101. There are four sets of linear motors 103, which are embedded in the two ends of the upper surface of the workbench 101. The panel mounting slot 104 is opened on the upper surface of the workbench 101. The detachable panel 105 is slidably engaged with the inside of the panel mounting slot 104, and the detachable panel 105 and the panel mounting slot 104 are fixed to each other at the four corners by bolts.

[0049] In this embodiment, the detachable panel 105 that actually places the stamped parts is designed to be replaceable. For stamped parts of different shapes to be ground, different limiting fixtures can be replaced to further improve the adaptability of the overall structure to the shape of the stamped parts to be ground.

[0050] like Figure 1-4 As shown, in this embodiment, the moving structure 2 further includes a crossbeam 201, a second linear motor 203, a third linear motor 204, and sliding bases 205. Support columns 202 are fixedly installed on the bottom sides of both ends of the crossbeam 201, and the lower ends of the support columns 202 are fixedly connected to the internal slider of the first linear motor 203. The second linear motor 203 is embedded in the upper edge of one side surface of the crossbeam 201; the third linear motor 204 is embedded in the lower edge of one side surface of the crossbeam 201. There are two sliding bases 205, which are slidably installed at both ends of one side of the crossbeam 201. One sliding base 205 is fixedly connected to the internal slider of the second linear motor 203, and the other sliding base 205 is fixedly connected to the third linear motor 204. The internal sliders of the linear motor 204 are fixedly connected to each other; the moving structure 2 also includes an internal threaded sleeve 206, an external gear ring 207, a first motor 208, and a lead screw 210. The internal threaded sleeve 206 is rotatably mounted on one end of the sliding base 205 via a bearing; the external gear ring 207 is fixedly sleeved on the upper end of the internal threaded sleeve 206; the first motor 208 is embedded inside the sliding base 205, and a gear 209 that interacts with the external gear ring 207 is fixedly installed at the output end of the first motor 208; the lead screw 210 is screwed into the internal threaded sleeve 206, and limit grooves 212 are opened on both sides of the lead screw 210. The limit grooves 212 are slidably engaged with the limit sliders 211 fixedly installed on both sides of the lower opening of the internal threaded sleeve 206.

[0051] In practice, linear motor 103 pushes support column 202, which in turn pushes two crossbeams 201 to slide freely on the front and rear surfaces of the worktable 101. Then, linear motor 204 controls the sliding bases 205 at both ends of one side of the crossbeams 201 to slide freely, thereby enabling the grinding structure 3 to move freely on the X and Y axes of the worktable 101. In conjunction with motor 208 rotating external gear ring 207, the external gear ring 207 drives the internal threaded sleeve 206 to rotate, which in turn moves the lead screw 210 up and down, adjusting the actual height of the grinding structure 3. This facilitates grinding of various parts of the impact component and provides high flexibility in use. Example 2

[0052] Based on Embodiment 1, in order to compensate for the limitation mentioned in Embodiment 1 that when the connecting seat 307 is controlled to tilt by the electric push rod 306 on one side of the substrate 304, it is limited by the range of motion and installation position of the electric push rod 306, and can only control the connecting seat 307 to tilt to one side, but cannot tilt in the opposite direction, resulting in a certain dead angle in the grinding angle.

[0053] like Figure 5-6 As shown, in this embodiment, the grinding structure 3 further includes an adjusting base 301, a second motor 302, a steering wheel 303, a third motor 308, a magnetic base 309, a grinding head 311, and fastening bolts 312. The adjusting base 301 is fixedly installed on the lower end of the lead screw 210; the second motor 302 is embedded inside the adjusting base 301; the steering wheel 303 is fixedly connected to the output end of the second motor 302, and one side edge of the bottom of the steering wheel 303 is flush with the base plate 308. 4. Mutual fixed connection; No. 3 motor 308 is fixedly installed on the upper end of the connecting seat 307; the magnetic seat 309 and No. 3 motor 308 pass through the output end of the connecting seat 307 and are mutually fixedly connected; the metal snap plate 310 and the magnetic seat 309 are mutually attracted and snapped together; the grinding head 311 is fixedly installed on the bottom side of the metal snap plate 310; the fastening bolt 312 passes through the grinding head 311, the metal snap plate 310 and the magnetic seat 309 and are screwed together.

[0054] In practice, the extension and retraction of the electric actuator 306 can only control the connecting seat 307 to tilt to one side. However, the steering wheel 303 can be rotated by the second motor 302. The steering wheel 303 and the base plate 304 form a structure similar to an eccentric wheel, which can control the tilted connecting seat 307 to move in a ring and change direction. While changing the tilt angle of the connecting seat 307, it also has a certain effect on grinding the arc edge of the stamped part. At the same time, when changing the grinding head 311, it can be temporarily positioned by the metal clip plate 310 adsorbed on the bottom side of the magnetic seat 309, and then tightened by the fastening bolt 312, which facilitates the replacement of the grinding head 311. By changing different types of grinding heads 311, and with the ability of the connecting seat 307 to rotate and tilt, various work requirements can be met.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
