[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0043] Please refer to Figures 1 to 8 , a drilling device for processing roller guides provided by an embodiment of the present invention, the drilling device for processing roller guides includes a workbench 1, a drilling device 2, a bottom support assembly 3, a lateral positioning assembly 4, a vertical positioning assembly 5, and a fixture assembly 6;

[0044] Regarding the drilling device 2;

[0045] Please refer to Figure 3 , the drilling device 2 includes a base 21, the base 21 is fixed on the workbench 1, a column 22 is fixed at the upper end of the base 21, a swing arm 23 that can move up and down is installed on the column 22, a large box 24 that can move along its length direction is installed on the swing arm 23, a main shaft 25 extending to its lower end is provided inside the large box 24, and a drill bit 26 is fixed at the lower end of the main shaft 25.

[0046] It should be noted that in the drilling device 2, the large box 24 can move along the swing arm 23, and the swing arm 23 can move along the column 22 to adjust the position of the drill bit 26 for opening holes in the guide rail using the drill bit 26.

[0047] For the bottom support assembly 3;

[0048] Please refer to Figure 4 , the bottom support assembly 3 includes a mounting plate 31 which is bolted to the workbench 1. At one end of the mounting plate 31, two symmetrically arranged first positioning plates 32 are welded and fixed. The support rollers 33 are rotatably connected to the first positioning plates 32 through shafts.

[0049] It should be noted that in the bottom support assembly 3, the mounting plate 31 and the first positioning plates 32 form a frame structure. The mounting plate 31 can be bolted to the workbench 1 to ensure its own stability. And a plurality of support rollers 33 arranged in a row are installed on the first positioning plates 32, which form a roller conveying structure. The guide rail to be processed can be placed on this conveying structure. The support rollers 33 can support the guide rail, and at the same time, the friction between them and the guide rail is relatively small, which is conducive to the subsequent automatic feeding of the guide rail.

[0050] For the lateral positioning assembly 4, it includes a left positioning part and a right positioning part;

[0051] Please refer to Figure 5 , the left positioning part includes a first support 41 which is bolted to the upper end of the workbench 1. On one side of the first support 41, a first mounting seat 42 is provided. There is a certain distance between the first mounting seat 42 and the first support 41. And on one side of the first mounting seat 42, a plurality of first positioning rods 43 distributed in a square shape are vertically fixed. The other ends of the first positioning rods 43 pass through the first support 41 and are slidably connected thereto, so that the first mounting seat 42 has a certain horizontal displacement floating amount. A first spring 44 that abuts against the first support 41 and the first mounting seat 42 is also sleeved on the first positioning rods 43;

[0052] Among them, the positioning wheel 45 is rotatably mounted on the first mounting seat 42 through a shaft.

[0053] It should be noted that for the lateral positioning assembly 4, it includes a left positioning part and a right positioning part. For the left positioning part, its first mounting seat 42 is installed on the first support 41 through multiple first positioning rods 43, and the first positioning rods 43 are slidably connected to the first support 41. Therefore, the first mounting seat 42 can move relative to the first support 41. And there is also a first spring 44 on the first positioning rods 43. One end of the first spring 44 abuts against the first support 41, and the other end abuts against the first mounting seat 42, so as to be able to generate an elastic force on the first mounting seat 42, enabling the first mounting seat 42 to move towards the position of the right positioning part.

[0054] Please refer to Figure 5 , the right positioning part includes a second tripod 46, and the second tripod 46 is bolted to the upper end of the workbench 1. A second mounting seat 47 is bolted to one side of the second tripod 46;

[0055] Among them, the driving wheel 48 is rotatably mounted on the second mounting seat 47 through a shaft, and a motor for driving the driving wheel 48 to rotate is also mounted on the second mounting seat 47;

[0056] The surface of the driving wheel 48 has a layer of rubber. Under normal conditions, the driving wheel 48 exerts a certain extrusion on the guide rail in cooperation with the positioning wheel 45, increasing the friction force between the driving wheel 48 and the guide rail.

[0057] It should be noted that for the right positioning part, its second mounting seat 47 is directly fixed on the second tripod 46 and is stably installed by itself. It has a driving wheel 48 corresponding to the positioning wheel 45. Under normal conditions, the first mounting seat 42 moves towards the position of the second mounting seat 47 under the elastic force of the first spring 44. Therefore, the distance between the positioning wheel 45 and the driving wheel 48 is smaller than the width of the guide rail itself, so that the positioning wheel 45 and the driving wheel 48 clamp the guide rail. At the same time, there is a rubber sleeve on the driving wheel 48, which can increase the friction force between it and the guide rail. A motor is also mounted on the second mounting seat 47, and the motor can drive each driving wheel 48 to rotate synchronously through a sprocket and chain transmission structure. Because the driving wheel 48 is in direct contact with the guide rail, the guide rail can be driven to move by using the friction force, thus realizing the automatic feeding of the guide rail; moreover, when the positioning wheel 45 cooperates with the driving wheel 48 to clamp the guide rail, it also has a positioning effect on the guide rail.

[0058] For the vertical positioning component 5;

[0059] Please refer to Figure 6 , the vertical positioning component 5 includes two groups of third tripods 51, and both groups of third tripods 51 are bolted to the upper end of the workbench 1. A horizontally arranged second positioning plate 52 is welded and fixed to one side of the third tripod 51, and a second positioning rod 53 is vertically welded to the lower end of the second positioning plate 52;

[0060] A bearing seat 54 is also arranged on one side of the third tripod 51. A cross plate 55 is welded and fixed to one side of the bearing seat 54. The second positioning rod 53 passes through the cross plate 55 and is slidably connected thereto. A second spring 56 for pressing against the second positioning plate 52 and the cross plate 55 is also sleeved on the second positioning rod 53;

[0061] Among them, the pressing wheel 57 is rotatably mounted on the bearing seat 54 through a shaft, and an infrared rangefinder 58 for measuring the moving distance of the guide rail is also mounted on the second positioning plate 52.

[0062] It should be noted that for the vertical positioning component 5, it has a pressing wheel 57 which can contact the upper end face of the guide rail, so as to exert a certain extrusion force on the guide rail in the vertical direction, thereby further positioning the guide rail;

[0063] The pressing wheel 57 is installed on the bearing seat 54. There is a cross plate 55 on the side of the bearing seat 54. At the same time, a second positioning plate 52 is fixed on the third tripod 51. There are multiple second positioning rods 53 on the second positioning plate 52. The second positioning rods 53 are slidably connected to the cross plate 55, so as to realize the installation and positioning of the bearing seat 54 and the pressing wheel 57. At the same time, there is also a second spring 56 on the second positioning rod 53. The elastic force generated by the second spring 56 on the cross plate 55 makes the pressing wheel 57 have a driving force to move downward. Therefore, when contacting the guide rail, it can exert a certain extrusion force on the guide rail to realize the positioning of the guide rail;

[0064] An infrared rangefinder 58 is also installed on the second positioning plate 52. The light emitted by the infrared rangefinder 58 can continuously irradiate on the guide rail. Therefore, when the guide rail moves, the moving distance of the guide rail can be measured in real time by using the infrared rangefinder 58.

[0065] For the fixture assembly 6;

[0066] Please refer to Figure 7 and Figure 8 , the fixture assembly 6 includes a third mounting seat 61 which is bolted to the workbench 1. A cylinder 63 is fixed to the lower end of the third mounting seat 61. The output end of the cylinder 63 passes through the third mounting seat 61 and is fixed with a pressing block 64. One side of the pressing block 64 is integrally connected with an inclined insert block 65;

[0067] A chute 62 is also provided at the upper end of the third mounting seat 61. A slider 66 is movably installed inside the chute 62. There is an inclined slot 67 on the slider 66. The insert block 65 is slidably connected inside the slot 67. The other side of the slider 66 is fixed with a pressing plate 68.

[0068] It should be noted that for the fixture assembly 6, it can be used in cooperation with the right positioning part to clamp and fix the guide rail. When the track is in a stable state, the drilling device 2 is used for hole opening processing;

[0069] The third mounting seat 61 is fixed to the workbench 1. A cylinder 63 is installed at its lower end, and the output end of the cylinder 63 is fixed with a pressing block 64. Thus, the cylinder 63 can be used to drive the pressing block 64 to move up and down. There is also a chute 62 at the upper end of the third mounting seat 61. A slider 66 is slidably connected inside the chute 62. One side of the slider 66 is fixed with a pressing plate 68. The moving direction of the slider 66 is the position close to or away from the bottom support assembly 3. Therefore, it can cooperate with the driving wheel 48 to clamp and fix the guide rail;

[0070] The extrusion block 64 is provided with an inclined insert block 65, and one side of the sliding block 66 is provided with an inclined insert groove 67. The insert block 65 is embedded into the insert groove 67 and is slidably connected thereto. Therefore, during the lifting movement of the extrusion block 64, a force can be generated on the sliding block 66, enabling the sliding block 66 to move in the horizontal direction.

[0071] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
