DETAILED DESCRIPTION

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

[0022] Figure 1 It is a schematic diagram of the front structure of the electromagnet clamp in the prior art. Figure 2 It is a schematic diagram of the side structure of the electromagnet clamp in the prior art, such as Figure 1 , Figure 2 As shown, the electromagnet clamp 4 processed and formed in the prior art includes two parts, namely, a hoop 401 and a straight groove 402. The hoop part is an annular structure with an opening, and the straight groove part is formed by extending a length from the openings on both sides of the hoop. The clamp is formed by bending an initial plate as a whole. It is necessary to mark the bent workpiece according to the standard size, so as to cut off the excess part of the clamp. In the prior art, the benchwork process is often used for marking and alignment. Due to its inconvenient positioning, it is easy to cause alignment difficulties, thereby affecting the overall processing quality and efficiency.

[0023] To solve the above problems, an embodiment of the present invention provides an electromagnetic clamp marking and positioning device, comprising: a base 1, the base 1 is provided with a first positioning hole 101 and a fixing hole 102 arranged side by side; a positioning mandrel 2, the middle part of the positioning mandrel 2 is provided with a second positioning hole 201, and the diameter of the positioning mandrel 2 is smaller than the inner diameter of the hoop of the clamp to be processed; a positioning pin, the positioning pin is used to pass through the second positioning hole 201 and the first positioning hole 101 to position the positioning mandrel 2 on the base 1; a fastening pin 3, the fastening pin 3 is used to pass through the straight groove of the clamp to be processed and then connect with the fixing hole 102.

[0024] Figure 3 is a schematic structural diagram of the base of the electromagnet clamp marking device provided in an embodiment of the present invention, such as Figure 3 As shown, the base 1 is substantially a cube, and is provided with a first positioning hole 101 and a fixing hole 102. When in use, Figure 3 The surface shown is in a vertical state, at which time the fixing hole 102 is located above the first positioning hole 101, and the first positioning hole 101 and the fixing hole 102 are both in a horizontal state.

[0025] Figure 4 is a schematic diagram of the structure of the positioning mandrel provided in an embodiment of the present invention, such as Figure 4As shown, the positioning mandrel 2 is cylindrical, and a through second positioning hole 201 is provided in the middle thereof, and the second positioning hole 201 is provided corresponding to the first positioning hole 101, and a positioning pin can be inserted. The diameter of the positioning mandrel 2 is slightly smaller than the inner diameter of the hoop of the electromagnet clamp, and the positioning mandrel 2 has a certain thickness, which can ensure that the hoop can be inserted into the positioning mandrel 2 without causing a large swing of the hoop.

[0026] Figure 5 is a schematic diagram of the structure of the fastening pin provided in an embodiment of the present invention, such as Figure 5 As shown, the fastening pin 3 can pass through the straight groove of the electromagnet clamp and connect with the fixing hole 102 on the base 1, so that the straight groove part of the clamp is also positioned, and the straight groove part of the clamp will not shake significantly.

[0027] The hoop part is positioned by the positioning mandrel 2, and the straight groove part is positioned by the fastening pin 3, so as to ensure that the electromagnet clamp is vertically fixed on the base 1 with the straight groove part on the top and the hoop part on the bottom. At this time, the marking tool can be operated to mark the size at the corresponding length position according to the size requirements of the part. Furthermore, although the length of the straight groove part is different after different clamps are bent, the two points of the clamp remain unchanged through the positioning of the positioning mandrel 2 and the fastening pin 3, that is, the center of the hoop and the center of the straight groove remain unchanged. Therefore, the marking tool can be horizontally connected to a fixed position on a rod, and all clamps can be uniformly marked by the combined tool, without measuring the length for marking each time, thereby improving the marking efficiency.

[0028] The steps for using the device in this embodiment are as follows:

[0029] 1. Insert the positioning pin through the second positioning hole of the positioning mandrel into the first positioning hole of the base;

[0030] 2. Place the hoop of the clamp to be processed on the outside of the positioning mandrel;

[0031] 3. Pass the fastening pin through the straight groove of the hoop to be processed and connect it to the fixing hole;

[0032] 4. Use a height gauge to mark the length dimension line of the clamp to be processed according to the process requirements of the drawing;

[0033] 5. Unscrew the fastening pin and take out the clamp, completing the marking process of a clamp;

[0034] 6. Repeat the above steps to complete the marking process of the next clamp.

[0035] As an optional implementation, the fixing hole 102 is a threaded hole; the fastening pin 3 is threadedly connected to the fixing hole 102 .

[0036] In order to improve the fixing effectiveness of the clamp, the fixing hole 102 is set as a threaded hole in this embodiment, and the fastening pin shaft 3 passes through the straight groove and is threadedly connected to the fixing hole 102, thereby ensuring that the fastening pin shaft 3 will not shake left and right, thereby ensuring the stability of the electromagnet clamp.

[0037] As an optional embodiment, the fastening pin 3 includes a first connecting rod 301, a second connecting rod 302 and a third connecting rod 303 with increasing diameters in sequence; the outer wall of the first connecting rod 301 is provided with an external thread; the diameter of the second connecting rod 302 is the same as the width of the straight groove of the clamp to be processed, and the length is greater than the thickness of the clamp to be processed; the diameter of the third connecting rod 303 is greater than the width of the straight groove.

[0038] like Figure 5 As shown, the fastening pin 3 includes a first connecting rod 301, a second connecting rod 302 and a third connecting rod 303 which are arranged in sequence, wherein the diameters of the first connecting rod 301, the second connecting rod 302 and the third connecting rod 303 increase in sequence.

[0039] The outer wall of the first connecting rod 301 is provided with a thread, which is matched with the thread of the fixing hole 102, and the diameter of the first connecting rod 301 is smaller than the width of the straight groove. The first connecting rod 301 can pass through the straight groove of the clamp and be threadedly connected to the fixing hole 102 without any obstacles.

[0040] The outer wall of the second connecting rod 302 has no threads, and its diameter is the same as the width of the straight groove, so it can be installed in the straight groove space. Its length is slightly larger than the thickness of the clamp, ensuring that when the first connecting rod 301 is connected to the fixing hole 102, the clamps on both sides of the straight groove can fully contact the outer wall of the second connecting rod 302 without shaking.

[0041] The diameter of the third connecting rod 303 is larger than the width of the straight groove, and can be clamped on the clamps on both sides of the straight groove to adjust the length of the third connecting rod 303 extending into the clamps.

[0042] As an optional implementation, the distance from the center of the first positioning hole 101 to the bottom edge of the base 1 is greater than the radius of the clamp to be processed.

[0043] The theoretical maximum radius of the electromagnet clamp is 0.5 mm. The distance between the first positioning hole 101 and the bottom edge of the substrate 1 should be greater than the radius of the processed clamp to ensure that when the electromagnet clamp is arranged on the substrate 1, its bottom will not protrude from the bottom edge of the substrate 1 and cause wear.

[0044] As an optional implementation, the thickness of the positioning mandrel 2 is greater than the thickness of the clamp to be processed.

[0045] The thickness of the positioning mandrel 2 is greater than the thickness of the clamp to be processed, so that the inner wall of the clamp ring to be processed can fully contact the outer wall of the positioning mandrel 2, thereby ensuring the stability of positioning.

[0046] As an optional implementation, the thickness difference between the positioning mandrel 2 and the clamp to be processed is 1 mm.

[0047] The thickness of the positioning mandrel 2 is 1 mm greater than the thickness of the clamp to be processed. For the clamp that may have thickness error after bending, the positioning mandrel 2 can complete the stable positioning function.

[0048] As an optional implementation, a line connecting the center of the first positioning hole 101 and the center of the fixing hole 102 is in a vertical state.

[0049] The center of the first positioning hole 101 and the midline of the fixing hole 102 are connected as a vertical line, ensuring that when the base 1 is vertically arranged, the clamp positioned on the base 1 can also maintain a vertical state to facilitate marking in the height direction.

[0050] As an optional implementation, the distance from the center of the first positioning hole 101 to the center of the fixing hole 102 is the same as the distance from the center of the hoop to the center of the straight groove.

[0051] The distance from the center of the first positioning hole 101 to the center of the fixing hole 102 is the same as the distance from the center of the hoop to the center of the straight groove, ensuring that when the clamp is positioned, the center of the hoop coincides with the first positioning hole 101, and the center of the straight groove coincides with the center of the fixing hole 102. After the two points are positioned, marking is performed to ensure marking accuracy.

[0052] The above technical solution has the following beneficial effects: the bent clamp is positioned by tightening the pin shaft and the positioning core shaft, and the bottom of the clamp is used as a reference to mark the vertically arranged clamp, thereby solving the problem of inconvenient positioning, and the positioned clamp is marked uniformly, which improves the marking efficiency and marking quality, thereby improving the quality of the formed clamp.

[0053] The specific implementation methods of the above invention further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above content is only the specific implementation methods of the present invention and is not intended to limit the protection scope of the present invention.
