DETAILED DESCRIPTION
[0025] 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.
[0026] Embodiment 1: Since the prior art does not have an adjustment structure for multiple drill bits, the positions of the drill bits used for drilling are mostly fixed. When facing various needs, the positions of the drill bits cannot be adjusted quickly, and the only way is to replace multiple drill bits, which affects the processing efficiency. To solve this problem, the following technical solution is proposed:
[0027] Refer to the instruction manual Figure 1-Figure 7 , a semi-axle horizontal automatic drilling device for engineering machinery, such as Figure 1 and Figure 2 As shown, it comprises a processing table 1, a fixture seat 2 is arranged on the top of the processing table 1, a half-shaft rod 3 is arranged on the top of the fixture seat 2, a clamping mechanism 4 is arranged on the top of the processing table 1, and a distance mechanism 5 is arranged on the inner wall of the processing table 1;
[0028] like Figure 2 and Figure 3 As shown, the clamping mechanism 4 includes a positioning seat 41 fixedly installed on the top of the processing table 1, a straight rod 42 is fixedly installed on one side of the positioning seat 41, the straight rod 42 is arranged in a horizontal state, and a plurality of clamping rods 43 are hinged on the outer wall of the positioning seat 41, and the plurality of clamping rods 43 are arranged in a ring-shaped and equidistant manner, and the same angle is adjusted together on one side of the positioning seat 41 through the plurality of clamping rods 43.
[0029] like Figure 3 , Figure 4 and Figure 5As shown, a push ring 44 is slidably installed on the outer wall of the plurality of clamping rods 43, and the push ring 44 is arranged in a vertical state. The inner wall of the push ring 44 is arranged in an inclined upward state. The push ring 44 and the outer walls of the plurality of clamping rods 43 are staggered with each other. A slip ring 45 is fixedly installed on the inner wall of the push ring 44. The slip ring 45 is slidably installed on the outer wall of the straight rod 42, and then the push ring 44 slides on the outer wall of the straight rod 42 through the slip ring 45, and then the push ring 44 squeezes the plurality of clamping rods 43 to shrink, and a push slider 46 is hinged on one side of the plurality of clamping rods 43, and then the plurality of clamping rods 43 drive the plurality of push sliders 46 to shrink and move synchronously, and a joint block 47 is slidably installed on one side of the plurality of push sliders 46, and a fixed disk 48 is slidably installed on the outer walls of the plurality of joint blocks 47, and the fixed disk 48 is fixedly installed on the top of the processing table 1, so that the plurality of push sliders 46 drive the plurality of joint blocks 47 to slide on the inner wall of the fixed disk 48.
[0030] like Figure 3 and Figure 5 As shown, a motor 49 is fixedly installed on one side of the multiple linkage blocks 47, a drill bit 410 is provided on one side of the multiple motors 49, and the multiple drill bits 410 are arranged in a horizontal state. A limit spring 411 is fixedly installed on the outer wall of the multiple linkage blocks 47, and the limit spring 411 is fixedly installed on the inner wall of the fixed plate 48. Then, the multiple linkage blocks 47 drive the motor 49 and the drill bit 410 to synchronously move a corresponding distance, and pull the limit spring 411, so that the multiple drill bits 410 can synchronously adjust their positions and correspond to the semi-axle rod 3.
[0031] like Figure 3 As shown, the spacing mechanism 5 includes a push plate 51 fixedly mounted on the bottom of the push ring 44, the bottom of the push plate 51 is threadedly connected with a threaded rod 52, the threaded rod 52 is rotatably mounted on the inner wall of the processing table 1, and a dial wheel 53 is fixedly mounted on one side of the threaded rod 52. The rotation of the dial wheel 53 drives the threaded rod 52 to rotate synchronously, and then the threaded rod 52 drives the push plate 51 to make the push ring 44 move synchronously.
[0032] like Figure 3 As shown, a swivel ring 54 is rotatably installed on the outer wall of the push plate 51, and the swivel ring 54 is sleeved on the outer wall of the threaded rod 52. A support spring 55 is fixedly installed on one side of the swivel ring 54, and the support spring 55 is fixedly installed on the inner wall of the processing table 1. Therefore, when the push plate 51 moves, the push plate 51 is continuously stressed and stuck on the outer wall of the threaded rod 52 through the elastic squeezing of the swivel ring 54 and the support spring 55, so as to prevent the push plate 51 from shaking by itself and moving on the outer wall of the threaded rod 52.
[0033] In the specific implementation, the threaded rod 52 is driven to rotate synchronously by rotating the dial wheel 53, and then the threaded rod 52 drives the push plate 51 to make the push ring 44 move synchronously, and the push ring 44 slides on the outer wall of the straight rod 42 through the slip ring 45, and the push ring 44 squeezes the multiple clamping rods 43 to shrink. At this time, the multiple clamping rods 43 adjust the same angle together on one side of the positioning seat 41, and then the multiple clamping rods 43 drive the multiple push sliders 46 to shrink and move synchronously, so that the multiple push sliders 46 drive the multiple joint blocks 47 to slide on the inner wall of the fixed plate 48, and the multiple joint blocks 47 drive the motor 49 and the drill bit 410 to move synchronously by a corresponding distance, so that the multiple drill bits 410 can adjust their positions synchronously and correspond to the processing positions of the half-axis rod 3, that is, the position of the drill bit 410 is adjusted according to needs during use to avoid the need for replacement, thereby improving processing efficiency.
[0034] Embodiment 2: The existing drill bit does not have a dedicated protective structure after work, resulting in the drill bit being exposed to the outside world and being damaged by collision. To solve this problem, the following technical solution is proposed:

The inner walls of the plurality of top frames 61 are rotatably installed with sleeve boxes 62, and the plurality of sleeve boxes 62 are arranged in an inclined state. When the plurality of connecting blocks 47 are folded up, the plurality of sleeve boxes 62 in the plurality of top frames 61 are squeezed by the corresponding plurality of connecting blocks 47 to be in a horizontal state, and then the plurality of sleeve boxes 62 are sleeved on the outside of the corresponding drill bits 410.
[0036] like Figure 6 and Figure 7 As shown, one side of the plurality of sleeves 62 is provided with a groove, the inner wall of the groove is fixedly installed with a sponge board 63, the plurality of sleeves 62 and the drill bit 410 are arranged corresponding to each other, the outer wall of the plurality of sleeves 62 is fixedly installed with a top pressure spring 64, and the plurality of top pressure springs 64 are fixedly installed on the inner wall of the top frame 61. The sponge board 63 is driven by the plurality of sleeves 62 to stretch the top pressure spring 64 to cover the outer wall of the plurality of drill bits 410, thereby protecting the drill bits 410 and preventing the drill bits 410 from being exposed to the outside and being damaged by collision.
[0037] In a specific implementation, when the drilling work is completed and the multiple joint blocks 47 are put away, the multiple sleeve boxes 62 in the multiple top frames 61 are squeezed by the corresponding multiple joint blocks 47 and become horizontal, and then the multiple sleeve boxes 62 drive the sponge plates 63 and stretch the top pressure springs 64 to move, that is, they are sleeved on the outside of the corresponding drill bit 410 and cover it, thereby protecting the drill bit 410 and preventing the drill bit 410 from being exposed to the outside and being damaged by collision.
