Description

Technical Field

[0001] This utility model belongs to the field of drill bit processing technology, specifically relating to a processing equipment for coal mine mechanical drill bits. Background Technology

[0002] Humans have recorded the use of coal since the Neolithic Age. Its primary use is as fuel. The earliest commercial coal mines in the United States were located in Virginia, where mining began in 1748. Coal became a major energy source during the 18th-century Industrial Revolution, with steam trains and steamships becoming primary modes of transportation in industrialized nations. The steel industry also required large quantities of coal. Urban lighting, heating, and cooking also necessitated the use of coal gas.

[0003] Most drill bits used in coal mining machinery are machined using milling cutters. Milling cutters can move in multiple dimensions, but the clamps underneath are fixed. This increases the frequency of milling cutter movement and reduces work efficiency to some extent. Utility Model Content

[0004] The purpose of this utility model is to provide a processing equipment for coal mine mechanical drill bits, so as to solve the problem in the prior art that the milling cutter needs to be moved frequently because the clamp is stationary.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A processing device for coal mine drill bits includes a base, a side plate fixed to the side of the base, a milling cutter holder mounted on the side of the side plate, a multi-dimensional movable milling cutter mounted on the bottom of the milling cutter holder, a first mounting groove on the base, a second mounting groove within the first mounting groove, a clamping assembly for clamping the drill bit within the second mounting groove, and an tilt adjustment assembly matching the clamping assembly mounted on the side of the base.

[0007] Preferably, the clamping assembly includes a sleeve, a support column is fixedly installed on the outside of the sleeve, a curved plate is fixedly installed on the upper end of the support column, two pairs of strip-shaped movable openings are evenly opened on the curved plate, and a clamping plate is slidably inserted into each of the strip-shaped movable openings; and two pairs of telescopic cylinders matching the four clamping plates are installed through the side of the curved plate.

[0008] Preferably, each of the clamping plates is provided with an anti-slip pad at its top, the film of the anti-slip pad is provided with anti-slip texture, and the anti-slip pad and the clamping plate are bonded together with an adhesive.

[0009] Preferably, the rotation angle range of the two sides of the bending plate is 0-40 degrees.

[0010] Preferably, the tilt adjustment assembly includes a long shaft fixedly inserted into the sleeve, the end of the long shaft away from the sleeve extending backward through the side of the base and fixedly sleeved with a second sprocket.

[0011] Preferably, a servo motor is fixedly installed on the side of the base, a short shaft is fixedly connected to the output end of the servo motor, a first sprocket is fixedly sleeved at the end of the short shaft, and a transmission chain belt for linkage between the first sprocket and the second sprocket is provided.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This utility model transforms the originally fixed clamp into a clamping component that can tilt left and right. This, combined with the original multi-dimensional mobility of the milling cutter, can improve the efficiency and flexibility of milling cutter operation. This can reduce the frequency of milling cutter movement, thereby improving the efficiency of equipment operation to a certain extent.

[0014] 2. In this utility model, the angle tilt adjustment of the clamping component is achieved by the rotation of the long shaft. The long shaft is connected to the output end of the servo motor through the second sprocket, the transmission chain belt, the first sprocket, and the short shaft. For the long shaft, the angle tilt adjustment of the clamping component is more flexible and faster. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1 and Figure 2 As shown, this utility model provides a processing equipment for coal mine mechanical drill bits, including a base 1, a side plate 2 fixed to the side of the base 1, a milling cutter seat 3 installed on the side of the side plate 2, a multi-dimensional movable milling cutter 4 installed at the bottom of the milling cutter seat 3, a first mounting groove 11 opened on the base 1, a second mounting groove 12 opened in the first mounting groove 11, a clamping component 6 for clamping the drill bit is provided in the second mounting groove 12, and an tilting component 5 matching the clamping component 6 is installed on the side of the base 1.

[0023] In summary, this application transforms the originally fixed clamp into a clamping component 6 that can tilt left and right. This, combined with the original multi-dimensional mobility of the milling cutter 4, can improve the efficiency and flexibility of the milling cutter 4's operation, thereby improving the efficiency of the equipment operation to a certain extent.

[0024] In a further embodiment, refer to Figure 3 and Figure 4 The clamping assembly 6 includes a sleeve 61, a support column 62 fixedly installed on the outside of the sleeve 61, a curved plate 63 fixedly installed on the upper end of the support column 62, two pairs of strip-shaped movable openings 631 evenly opened on the curved plate 63, and a clamping plate 64 is slidably inserted into each strip-shaped movable opening 631; and two pairs of telescopic cylinders 65 matching the four clamping plates 64 are installed through the side of the curved plate 63.

[0025] The bending plate 63 has a rotation angle range of 0-40 degrees on both sides, totaling approximately 80 degrees.

[0026] In this embodiment, the rotation of the sleeve 61 can drive the bending plate 63 on it to rotate. As a platform on which the drill bit part is attached, the rotation of the bending plate 63 will inevitably cause the drill bit part to rotate synchronously. This, combined with the original multi-dimensional mobility of the milling cutter 4, can improve the efficiency and flexibility of the milling cutter 4, thereby reducing the frequency of the milling cutter 4's movement.

[0027] In a further embodiment, refer to Figure 3 Each of the clamping plates 64 is provided with an anti-slip pad 641 at its top. The film of the anti-slip pad 641 is provided with anti-slip texture. The anti-slip pad 641 and the clamping plate 64 are bonded together with adhesive.

[0028] In this embodiment, during the process of pushing the clamping plate 64 closer together at the output end of the telescopic cylinder 65, the anti-slip pad 641 will contact the drill bit parts first, thereby avoiding the problem of unstable clamping, looseness, or lack of tightness of the drill bit parts caused by the flat clamping plate 64.

[0029] In a further embodiment, refer to Figure 3 The tilt adjustment assembly 5 includes a long shaft 56 fixedly inserted into the sleeve 61. The end of the long shaft 56 away from the sleeve 61 extends backward through the side of the base 1 and is fixedly sleeved with a second sprocket 55. A servo motor 51 is fixedly installed on the side of the base 1. The output end of the servo motor 51 is fixedly connected to a short shaft 52. The end of the short shaft 52 is fixedly sleeved with a first sprocket 53. A transmission chain belt 54 for linkage between the first sprocket 53 and the second sprocket 55 is provided.

[0030] In this embodiment, when the clamping component 6 needs to be rotated to adjust its angle, the servo motor 51 is started, which drives the short shaft 52 to rotate. The rotation of the short shaft 52 can drive the first sprocket 53 outside it to rotate. Then, through the cooperation of the transmission chain belt 54 and the second sprocket 55, the parallel long shaft 56 can be driven to rotate. In this way, the sleeve 61 sleeved outside the long shaft 56 will also rotate. This makes the angle adjustment of the clamping component 6 more flexible and faster.

[0031] 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.
