[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-Figure 6 A drilling machine for railway parts processing shown in the figure comprises a frame 1 with a cavity in the middle, a processing table 7 is arranged in the cavity, a clamping member 8 is arranged on the processing table 7, and an adjustable drilling assembly 6 is arranged on the frame 1;

[0029] The frame 1 is also provided with a flipping mechanism 9 for driving the processing table 7 to rotate, and the flipping mechanism 9 includes shafts 94 fixed on both sides of the processing table 7, and the opposite ends of the two shafts 94 respectively penetrate to the outside of the frame 1, and the end of the shaft 94 located on the front side is installed with an indicator needle 96, and the end of the shaft 94 located on the rear side is connected to a power part that drives it to rotate, and a dial 95 matching the indicator needle 96 is installed on the front side of the frame 1. The dial 95 is semicircular and has scale values ​​of 0°-180°.

[0030] Specifically, Figure 4 and Figure 5 As shown, the power part includes a mounting frame fixed to the rear side of the frame 1, on which a third motor 91 is mounted, and a main gear 92 is mounted on the main shaft of the third motor 91, and a sub-gear 93 meshing with the main gear 92 is fixed to the end of a shaft rod 94 located at the rear side.

[0031] Specifically, Figure 1-Figure 5 As shown, the clamping member 8 includes two symmetrically arranged clamping plates 81 and four fixed plates 82 symmetrically fixed on both sides of the top of the processing table 7. The four fixed plates 82 are each installed with a first electric push rod 83 on one side relative to the clamping plate 81, and the telescopic ends of the four first electric push rods 83 are respectively connected to one side of the two clamping plates 81.

[0032] Specifically, Figure 1-Figure 5 As shown, the drilling assembly 6 includes a second motor 61 , and a drill bit 62 is mounted on the main shaft of the second motor 61 .

[0033] When processing railway accessories, the railway accessories can be placed on the processing table 7 first, and then the two clamping plates 81 are driven to move toward each other by the first electric push rod 83 to clamp the railway accessories, and then the railway accessories are drilled by the adjustable drilling assembly 6, that is, the drill bit 62 is driven to rotate by the second motor 61 to realize the drilling processing of the railway accessories;

[0034] And during the processing, if the railway accessories need to be processed with an inclined hole, the main gear 92 can be driven to rotate by the third motor 91, and then the main gear 92 drives one of the shafts 94 to rotate through the sub-gear 93 meshing with it, so that the shaft 94 drives the processing table 7 to rotate in the cavity on the frame 1, and the other shaft 94 drives the indicator needle 96 at its end to rotate. At this time, the worker can watch the angle value on the dial 95 pointed by the indicator needle 96 to grasp the angle at which the processing table 7 drives the railway accessories to flip. When the railway accessories are flipped to the required angle, the third motor 91 is stopped, and the drill bit 62 is driven to rotate by the second motor 61 to perform inclined hole processing on the railway accessories, so that the drilling machine can meet the drilling needs of different angles, which increases the application range of the drilling machine and is conducive to the efficient processing of railway accessories.

[0035] Further, in order to realize the movement adjustment of the drilling assembly 6, as Figure 1-Figure 5 As shown, the frame 1 is also provided with a translation mechanism 3 for driving the drilling assembly 6 to move, and the translation mechanism 3 includes a support frame 2 mounted on the top of the frame 1, and a screw rod 32 rotatably installed on the top of the support frame 2, a first motor 31 for driving the screw rod 32 to rotate is fixed on one side of the support frame 2, a moving seat 33 is sleeved on the screw rod 32, and a second electric push rod 11 is installed at the bottom of the moving seat 33, and the second motor 61 is installed on the telescopic end of the second electric push rod 11.

[0036] When the drilling assembly 6 drills a railway accessory, the first motor 31 can be used to drive the screw rod 32 to rotate. At this time, the screw rod 32 drives the moving seat 33 to move horizontally along it, and then the moving seat 33 drives the second electric push rod 11 to move horizontally, so that the second electric push rod 11 drives the drill bit 62 to move horizontally. At the same time, the second motor 61 is driven to descend by the second electric push rod 11, so that the second motor 61 drives the drill bit 62 to slowly descend until the drill bit 62 contacts the railway accessory on the processing table 7, and then the drill bit 62 is driven to rotate by the second motor 61 to drill the railway accessory, thereby realizing the lateral and vertical movement adjustment of the drill bit 62, which is convenient for drilling holes in different positions of the railway accessories.

[0037] In addition, in one embodiment, if Figure 1-Figure 4 As shown, two protective plates 4 are also provided on the frame 1, and the two protective plates 4 are symmetrically distributed on both sides of the support frame 2, and a processing area is enclosed between the two protective plates 4 and the support frame 2, and a positioning block 10 is installed at one end of the two protective plates 4, and positioning grooves corresponding to the positioning blocks 10 are opened on both sides of the support frame 2, and latch rods 5 that pass through the positioning blocks 10 are also inserted on both sides of the support frame 2.

[0038] When processing railway accessories, the two protective plates 4 can be plugged into the two sides of the support frame 2 through the cooperation of the positioning block 10 and the positioning groove, and then the latch rod 5 can be inserted into the support frame 2 to plug and fix the positioning block 10 and the support frame 2 to complete the installation of the protective plates 4, so that the two protective plates 4 and the support frame 2 form a processing area, and then the railway accessories on the processing table 7 are processed through the drilling assembly 6. At this time, the protective plates 4 will block the debris, so that the debris is gathered in the processing area to prevent the debris from splashing, which is beneficial to the cleaning of the drilling machine and improves the cleaning efficiency.

[0039] Furthermore, if Figure 3 and Figure 4 As shown, guide bars are installed on both sides of the top of the frame 1, and guide grooves matching the guide bars are opened at the bottom ends of the two protection plates 4.

[0040] During the disassembly and assembly process of the protective plate 4 , the protective plate 4 slides along the guide bar through the guide groove at the bottom end thereof to limit the position between the protective plate 4 and the frame 1 , thereby facilitating the stable disassembly and assembly of the protective plate 4 .

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
