Technical Field
[0001] This utility model relates to the field of surface treatment equipment technology, specifically a tool for grinding the edges of laser-cut workpieces. Background Technology
[0002] Laser-cut workpieces produce burrs on their edges, which not only affect the appearance of the workpiece but also cause difficulties in subsequent processing; therefore, it is necessary to grind the edges of the laser-cut workpieces.
[0003] In the prior art, sandpaper or belt sanders are usually used to remove burrs from the edges of workpieces. However, when grinding workpieces with complex contours, the size limitations of belt sanders make it impossible to precisely control the grinding position, which may damage the areas of the workpiece that do not need to be ground. Sandpaper is also fragile, and during the grinding process, the sharp edges of the workpiece may penetrate the sandpaper, posing a potential safety risk to the operator. Therefore, this application provides a tool for grinding the edges of laser-cut workpieces. Utility Model Content

This tool can grind the edge of a workpiece with an arc-shaped sidewall, avoid damaging the parts of the workpiece that do not need to be ground, and improve the stability and safety of the tool.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0006] A laser-cut workpiece edge grinding tool is provided, including a workpiece positioning component and a grinding component; the workpiece positioning component includes a support and an electromagnet mounted on the support, the electromagnet being able to be magnetically attracted and coupled to the workpiece, the support being mounted on a base; the grinding component includes an inverted T-shaped grinding rod and a clamping cylinder movably mounted on the upper side of the outside of the T-shaped grinding rod, the outer side of the T-shaped grinding rod abutting against the side surface of the workpiece, and an outwardly protruding limiting edge is provided on the outer bottom of the T-shaped grinding rod, the top of the limiting edge and the bottom of the clamping cylinder abutting against the upper and lower side surfaces of the workpiece, respectively.
[0007] Furthermore, a stud is fixedly installed on the top of the inverted T-shaped grinding rod, and the clamping cylinder is connected to the stud by thread engagement.
[0008] Furthermore, the bottom edge of the clamping cylinder and the top edge of the limiting edge are respectively provided with guide cone surface I and guide cone surface II.
[0009] In this application, one possible technical solution for the gripping and moving of the stud is: a handle I is provided on the top of the stud.
[0010] In this application, another optional technical solution for the gripping and moving method of the stud is as follows: a column is fixedly installed on the top of the base, and an I-shaped sleeve is vertically slidably installed and rotatably installed on the column. The relative position of the I-shaped sleeve and the column is locked by fasteners. The I-shaped sleeve is rotatably installed inside the lifting arm, and a telescopic arm is slidably installed on the side of the lifting arm. The stud is detachably fixedly installed on the telescopic arm through a flange assembly, and a handle I is provided at the end of the telescopic arm away from the lifting arm.
[0011] Furthermore, two limiting components are detachably and fixedly installed on the top of the base, forming a positioning track between the two limiting components. The support is slidably connected to the positioning track, and a handle II is provided on the side of the support.
[0012] Furthermore, a damping pad is installed on the support, the upper side of the damping pad abuts against the bottom of the workpiece, and the damping pad is sleeved on the outer periphery of the electromagnet.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The laser-cut workpiece edge grinding tool of this utility model adjusts the distance between the limiting edge of the bottom of the T-shaped grinding rod and the clamping cylinder to limit the upper and lower sides of the workpiece, so that the T-shaped grinding rod can stably act on the side of the workpiece; the cross-section of the T-shaped grinding rod is circular, which can grind the edge of the arc-shaped side wall of the workpiece and the inner wall of the circular hole, and the T-shaped grinding rod and the side wall of the workpiece are in line contact, which can effectively avoid damage to the parts of the workpiece that do not need to be ground, resulting in good performance.
[0015] 2. The laser-cut workpiece edge grinding tool of this utility model uses an electromagnet to attract the workpiece and combines it with a damping pad to restrict the movement of the workpiece, so that the workpiece does not need to be held by hand, avoiding the sharp edge of the workpiece from causing cuts to the operator, and the tool is highly safe to use.
[0016] 3.

[0029] Example 1:
[0030] like Figure 1-2 As shown, this embodiment provides a laser-cut workpiece edge grinding tool, including a workpiece positioning component and a grinding component; the workpiece positioning component includes a support 14 and an electromagnet 15 mounted on the support 14, the electromagnet 15 can be magnetically attracted and coupled to the workpiece 1, and the support 14 is mounted on a base 11; the grinding component includes an inverted T-shaped grinding rod 25 and a clamping cylinder 26 movably mounted on the upper side of the outside of the T-shaped grinding rod 25, the outer side of the T-shaped grinding rod 25 abuts against the side surface of the workpiece 1, and the bottom outer side of the T-shaped grinding rod 25 is provided with an outwardly protruding limiting edge, the top of the limiting edge and the bottom of the clamping cylinder 26 abut against the upper and lower side surfaces of the workpiece 1 respectively.
[0031] The T-shaped polishing rod 25 of this application can be made of materials such as silicon carbide, cemented carbide, or tungsten carbide.
[0032] like Figure 1-4 As shown, a stud 24 is fixedly installed on the top of the inverted T-shaped grinding rod 25, and the clamping cylinder 26 is connected to the stud 24 by thread engagement. A torsion handle 27 is provided on the outer side of the clamping cylinder 26 to control the rotation of the clamping cylinder 26 relative to the stud 24.
[0033] In this embodiment, the top of the stud 24 is provided with a handle I. By holding the handle I, the synchronous movement of the inverted T-shaped grinding rod 25 and the clamping cylinder 26 can be controlled.
[0034] When using the laser-cut workpiece edge grinding tool of this application:
[0035] First, use electromagnet 15 to stably place workpiece 1 on support 14;
[0036] Next, adjust the distance between the bottom limiting edge of the T-shaped grinding rod 25 and the clamping cylinder 26 so that the top of the limiting edge and the bottom of the clamping cylinder 26 abut against the upper and lower surfaces of the workpiece 1, respectively.
[0037] Finally, the inverted T-shaped grinding rod 25 and the clamping cylinder 26 are moved synchronously, so that the T-shaped grinding rod 25 acts stably on the edge of the workpiece 1. The cross-section of the T-shaped grinding rod 25 is circular, which can grind the edge of the arc-shaped side wall of the workpiece 1 and the inner wall of the circular hole on the workpiece 1. Since the T-shaped grinding rod 25 and the side wall of the workpiece 1 are in line contact, it can effectively avoid damage to the parts of the workpiece 1 that do not need to be ground, and the effect is good.
[0038] To improve the position holding effect for workpiece 1, such as Figure 2 As shown, a damping pad 16 is installed on the support 14. The damping pad 16 is fitted around the outer periphery of the electromagnet 15, and the upper side of the damping pad 16 can abut against the bottom of the workpiece 1. The electromagnet 15 is used to attract the workpiece 1, and the movement of the workpiece 1 is restricted by the damping pad 16. Therefore, it is not necessary to hold the workpiece 1 by hand, and the sharp edge of the workpiece 1 is avoided from causing cuts to the operator. The tool is highly safe to use.
[0039] To facilitate the T-shaped grinding rod 25 and the clamping cylinder 26 in limiting the upper and lower sides of the workpiece 1, such as Figure 4 As shown, guide cone surface I and guide cone surface II are respectively provided on the bottom edge of the clamping cylinder 26 and the top edge of the limiting edge, so that the top of the limiting edge and the bottom of the clamping cylinder 26 abut against the upper and lower surfaces of the workpiece 1 respectively.
[0040] Example 2:
[0041] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1-4 As shown, in this embodiment, a column 12 is fixedly installed on the top of the base 11, and an I-shaped sleeve 22 is rotatably installed on the column 12. The relative position of the I-shaped sleeve 22 and the column 12 is locked by fasteners. The I-shaped sleeve 22 is rotatably installed in the lifting arm 21, and a telescopic arm 23 is slidably installed on the side of the lifting arm 21. The stud 24 is detachably fixed on the telescopic arm 23 through a flange assembly, and a handle I is provided at the end of the telescopic arm 23 away from the lifting arm 21.
[0042] The position of the I-shaped sleeve 22 on the column 12 is locked by fasteners so that the horizontal relative position between the inverted T-shaped grinding rod 25 and the workpiece 1 remains constant. Subsequently, by controlling the rotation of the lifting arm 21 on the outside of the I-shaped sleeve 22 and the sliding of the telescopic arm 23 on the side of the I-shaped sleeve 22, the position of the inverted T-shaped grinding rod 25 on the side wall of the workpiece 1 is changed.
[0043] Compared with the technical solution in Embodiment 1, this embodiment is more effective in maintaining the stability of the relative position of the inverted T-shaped grinding rod 25 and the workpiece 1.
[0044] Example 3:
[0045] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1-4 As shown, two limiting components 13 are detachably and fixedly installed on the top of the base 11, and a positioning rail is formed between the two limiting components 13. The support 14 is slidably connected to the positioning rail, and a handle II is provided on the side of the support 14.
[0046] Hold handle I and handle II with both hands respectively to adjust the relative positions of the workpiece positioning component and the grinding component. The operator does not need to hold workpiece 1 and the inverted T-shaped grinding rod 25 directly, making operation convenient and conducive to long-term grinding use.
