Technical Field

[0001] This utility model relates to the field of cylindrical pin processing technology, specifically to a grinding device for cylindrical pin processing that is easy to place. Background Technology

[0002] As is well known, pins are generally used to connect and lock parts or for assembly positioning. They can also be used as safety device parts. Cylindrical pins are fixed in holes by interference fit. Cylindrical pins are locating pins used to fix the relative position between parts. They are important auxiliary parts in assembly and processing. They are mainly used to fix parts, transmit power, or serve as positioning parts. Currently, the cylindrical pins need to be ground during processing, which requires the use of grinding equipment.

[0003] Existing grinding devices for cylindrical pins typically use a limiting mechanism to limit the cylindrical pin before grinding. However, these limiting mechanisms are usually fixed to the equipment, making it inconvenient to disassemble them when limiting cylindrical pins of different sizes. Utility Model Content

[0023] Please see Figure 1-5A grinding device for easily placed cylindrical pins includes a base plate 1, a through groove 3, a grinding mechanism 4, a workpiece 9, a fixing mechanism 10, and a limiting mechanism 15. The base plate 1 has a support base 2 at its bottom, and several support bases 2 are provided. The through groove 3 is opened on one side of the top of the base plate 1. The grinding mechanism 4 includes a connecting plate 5, a handle 8, a motor 6, and a grinding roller 7. The connecting plate 5 is placed on top of the base plate 1. One end of the motor 6 is connected to the bottom of the connecting plate 5, and the other end of the motor 6 extends into the through groove 3. The output end of the motor 6 is connected to the grinding roller 7. The handle 8 is located on top of the connecting plate 5. The fixing mechanism 10 includes a cylinder 11, a rubber layer 12, a connecting block 13, and a square block 14. The rubber layer 12 is disposed on the inner wall of the cylinder. The workpiece 9 extends into the cylinder 11 and contacts the rubber layer 12. An electromagnet is provided on the bottom wall of the inner wall of the cylinder 11, and the electromagnet attracts the bottom of the workpiece 9. The connecting block 13 is placed on top of the base plate 1. The cylinder 11 is disposed on the top of the connecting block 13. One end of the block 14 is connected to the bottom of the connecting block 13, and the other end of the block 14 passes through the base plate 1. The limiting mechanism 15 includes a first slot 16, a sliding block 17, a second slot 18, a first locking block 19, an electric push rod 20, a second locking block 21, and a limiting plate 22. The first slot 16 is formed on the connecting block 13, and the second slot 18 is formed on the base plate 1. One end of the sliding block 17 extends into the first slot 16. In this configuration, the other end of the sliding block 17 extends into the second slot 18, one end of the first locking block 19 is connected to the sliding block 17, and the other end of the first locking block 19 extends into the connecting block 13. One end of the electric push rod 20 is connected to the sliding block 17, and the other end of the electric push rod 20 is connected to one end of the second locking block 21. The other end of the second locking block 21 extends into the base plate 1, and one end of the limiting plate 22 is connected to the base plate 1. Two limiting mechanisms 15 are provided.

[0024] In use, first place the equipment in the designated location and connect it to the external mains power supply to power it. The grinding mechanism 4 has a separate connection cable for powering it (details omitted). Then, the support base 2 at the bottom of the base plate 1 provides support. Next, place the workpiece 9, which matches the cylinder 11, into the inner wall of the cylinder 11. The rubber layer 12 is slightly smaller than the workpiece 9 and has deformation capabilities. By forcefully inserting the workpiece 9 into the cylinder 11, the rubber layer 12 tightly wraps around the workpiece 9. Then, activate the electromagnet to attract and fix the workpiece 9. A control button is located on the outer wall of the cylinder 11; activating the control button starts or stops the electromagnet (details omitted). The workpiece 9 is made of iron, allowing the electromagnet to attract it. Most cylindrical pins on the market are made of iron or other materials that can be attracted by electromagnets (details omitted). Then, the operator holds the handle 8 on the connecting plate 5 and lifts it upwards, causing the connecting plate 5 to... The motor 6 and grinding roller 7 are separated from the through groove 3. Then, the motor 6 is started, driving the grinding roller 7 to rotate, so that the grinding roller 7 contacts the workpiece 9, and the edge of the workpiece 9 can be ground. When the operator holds the grinding mechanism 4, he / she can hold it with both hands at the same time. The operator knows how to hold the grinding mechanism 4 stably, which will not be described in detail here. When it is necessary to grind the other end of the workpiece 9, the workpiece 9 can be taken out from the cylinder 11. The other side of the workpiece 9 is inserted into the cylinder 11. Even if the other side of the workpiece 9 becomes smaller due to grinding, the size of the rubber layer 12 is slightly smaller than the size of the workpiece 9. Therefore, when the workpiece 9 is inserted into the cylinder 11, there will be no gap between the workpiece 9 and the inner wall of the cylinder 11, and it will be tightly wrapped by the rubber layer 12. The electromagnet is then started to attract the bottom of the workpiece 9, and the other side of the workpiece 9 can be ground. When the work is completed, the electromagnet is turned off so that the electromagnet no longer attracts the workpiece 9. Then the operator takes out the workpiece 9 and places the grinding mechanism 4 in the designated position on the base plate 1. Figure 1The process is as follows: When grinding workpieces 9 of different sizes is required, and the fixing mechanism 10 needs to be replaced, firstly, the electric push rod 20 is activated, driving the second locking block 21 to move, causing the second locking block 21 to separate from the interior of the base plate 1. Then, the operator manually pulls the sliding block 17, causing the sliding block 17 to move, thereby separating the first locking block 19 on the sliding block 17 from the interior of the connecting block 13. After the sliding block 17 is pulled to a certain position, the sliding block 17 will contact the limiting plate 22, which can prevent the sliding block 17 from separating from the first slot 16 and the second slot 18. After the first locking block 19 separates from the connecting block 13, the operator pulls the connecting block 13 upward, causing the connecting block 13 to rise, driving the square block 14 at the bottom of the connecting block 13 to rise, causing the square block 14 to separate from the base plate 1. Then, the operator... Hold the connecting block 13 and push it to move the sliding block 17, separating the sliding block 17 from the second slot 18. This separates the fixed structure from the equipment. Then, replace it with a fixed mechanism 10 that matches the workpiece 9. When this equipment leaves the factory, the manufacturer provides various sizes of fixed mechanisms 10, which will not be described in detail here. The electromagnets mentioned in this article are conventional technologies on the market, and their specific structures and working principles are well known to those skilled in the art, so they will not be described in detail here. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0025] The aforementioned limiting mechanism 15 has poor stability. To solve this problem, in this embodiment, the two limiting mechanisms 15 are symmetrically arranged.

[0026] The bottom of the support base 2 has poor anti-slip effect. When the bottom of the support base 2 comes into contact with a smooth ground, it is easy to slip. In order to solve this problem, in this embodiment, the bottom of the support base 2 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the bottom of the support base 2.

[0027] The stability of the aforementioned support base 2 is poor. To solve this problem, in this embodiment, several of the aforementioned support bases 2 are symmetrically arranged.

[0028] To improve the connection effect, in this embodiment, the handle 8 is welded to the connecting plate 5.

[0029] In order to facilitate the sliding of the sliding block 17 on the first slot 16 and the second slot 18, in this embodiment, the sliding block 17 is matched with the first slot 16 and the sliding block 17 is matched with the second slot 18.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
