Description

Technical field:

[0001] The utility model relates to the technical field of sliding bearings, and more specifically to a connecting hole processing device for a bearing seat. Background technology:

[0002] Sliding bearings generally include a bearing seat and a plurality of bearing shells installed in the bearing seat, and all the bearing shells form a circular sleeve shape;

[0003] The top surfaces of the left and right ends of the bearing housing at the bearing shell installation groove need to be processed with screw holes so that the upper bearing block can be pressed against the bearing housing and fixed to the bearing housing by bolts, and the screw part of the bolt needs to be screwed into the screw hole of the bearing housing;

[0004] Therefore, it is necessary to process screw holes on the top surfaces of the connecting parts at the left and right parts of the bearing shell mounting groove of the bearing seat. Generally, holes are first drilled by a drilling machine, and then the inner walls of the holes are threaded. The existing drilling equipment is generally a single-hole equipment. Therefore, the bearing seat needs to process four holes in succession. Moreover, during the processing, since the position of the drill bit is fixed, the bearing seat needs to be fixed and then after processing one hole, it needs to be disassembled and replaced, and another corresponding position needs to be drilled. The efficiency is very low. To complete the processing of a bearing seat, four loading and unloading operations are required, which is very inefficient and requires a large amount of manual labor. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for processing connecting holes of a bearing seat, which can continuously punch holes after the bearing seat is fixed, so as to achieve continuous completion of four holes without multiple loading and unloading, thereby greatly reducing the processing difficulty and improving the processing efficiency.

A locking nut 241 is threaded on the adjusting screw 24, and the rear end surface of the locking nut 241 is pressed against the front end surface of the push rod of the pushing cylinder 23.

[0021] This structure allows the distance between the push plate 252 and the front end surface of the push cylinder 23 to be changed by only loosening the locking nut 241 and rotating the adjusting screw 24, and then tightening the locking nut 241 to change the forward and backward movement position of the horizontal fixing plate 21.

[0022] Furthermore, the bearing seat 100 to be processed is placed in the middle of the top surface of the horizontal fixing plate 21 of the forward and backward moving mechanism 20, and the side positioning blocks 22 are installed on the left and right parts of the horizontal fixing plate 21.

The bottom end of the push rod of the lifting cylinder 31 extends out of the bottom surface of the top plate of the upper support frame 30 and is fixed with a lifting plate 32. A drilling motor 33 is fixed to the left and right parts of the top surface of the lifting plate 32. The bottom end of the output shaft of the drilling motor 33 extends out of the bottom surface of the lifting plate 32 and is fixed with a drill bit 34. The bottom end of the drill bit 34 faces the top surfaces of the left and right ends of the mounting groove of the bearing seat 100.

[0025] A plurality of vertical guide rods 321 are fixed on the top surface of the lifting plate 32 , and the vertical guide rods 321 are inserted into corresponding vertical through holes on the top plate of the upper support frame 30 .

[0026] Furthermore, the left and right parts of the top surface of the top plate of the main frame body 10 are fixed with guide rails 1 extending forward and backward, and the left and right parts of the bottom surface of the horizontal fixed plate 21 are fixed with guide support sliders 2, and the lower part of the guide support slider 2 is inserted into the guide groove of the corresponding guide rail 1 and cooperates with the guide groove.

[0027] Two positioning columns 3 are fixed to the left and right parts of the middle part of the top surface of the horizontal fixing plate 21. The positioning columns 3 are inserted into the corresponding through holes on the left or right part of the bearing seat 100, and the outer side walls of the positioning columns 3 are close to the inner side walls of the corresponding through holes. The positioning columns 3 can limit the bearing seat 100 and improve the effect of subsequent processing.

[0028] Furthermore, side connecting plates 25 are fixed on the left and right walls of the horizontal fixed plate 21, and clamping cylinders 26 are fixed on the front and rear parts of the outer walls of the side connecting plates 25. The end of the push rod of the clamping cylinder 26 extends out of the inner wall of the corresponding side connecting plate 25 and is fixed with a side positioning block 22. The inner end surface of the side positioning block 22 is pressed against the left or right wall of the bearing seat 100, and an upper limit positioning portion 221 is formed on the upper part of the inner end surface of the side positioning block 22. The bottom surface of the upper limit positioning portion 221 is an inclined wall surface extending obliquely from the outside to the inside and upward, and the outer end bottom surface of the inclined wall surface is pressed against the top end of the left or right wall of the bearing seat 100.

[0029] Furthermore, a self-lubricating sheet 229 is fixed to the bottom surface of the side positioning block 22 , and the bottom surface of the self-lubricating sheet 229 is in close contact with the top surface of the horizontal fixing plate 21 .

[0030] When this embodiment is in use, the bearing seat 100 is first placed on the horizontal fixing plate 21, so that the positioning column 3 is inserted into the corresponding through hole on the left or right part of the bearing seat 100 to achieve limiting; then, the push rod of the clamping cylinder 26 is pushed to make the inner end face of the side positioning block 22 press against the left side wall or the right side wall of the bearing seat 100, and the outer end bottom face of the inclined wall of the upper limit positioning part 221 presses against the top of the left side wall or the right side wall of the bearing seat 100, so that the bearing seat 100 is further fixed firmly.

[0031] Then, the drilling motor 33 is operated, and at the same time, the push rod of the lifting cylinder 31 pushes, so that the drill bit 34 rotates and descends to drill holes in the top surfaces of the components on both sides of the mounting groove of the bearing seat 100. At the initial position, the two drill bits 34 drill holes in the front of the top surfaces of the components on both sides of the mounting groove of the bearing seat 100. After completion, the push rod of the lifting cylinder 31 retracts, and then, the push rod of the pushing cylinder 23 pushes, so that the position of the bearing seat 100 is changed, so that the two drill bits 34 face the rear parts of the top surfaces of the components on both sides of the mounting groove of the bearing seat 100. Then, the push rod of the lifting cylinder 31 pushes, and the drilling motor 33 is operated, and holes can be drilled in the rear parts of the top surfaces of the components on both sides of the mounting groove of the bearing seat 100. It can perform four drillings in one clamping to complete the processing of a connecting hole of the bearing seat 100. It is efficient and effective, and greatly reduces the amount of manual labor.

[0032] Among them, when the push rod of the pushing cylinder 23 is pushed, its drill bit 34 cannot be aligned with the rear part of the top surface of the components on both sides of the installation groove of the bearing seat 100 that needs to be processed, the distance between the pushing plate 252 and the front end surface of the pushing cylinder 23 is changed by rotating the adjusting screw 24, thereby changing the forward and backward movement position of the horizontal fixed plate 21, thereby changing the position of the pushing plate 252, so that after the push rod of the pushing cylinder 23 is pushed subsequently, the drill bit 34 can be accurately aligned with the rear processing position of the top surface of the components on both sides of the installation groove of the bearing seat 100, meeting the processing needs and ensuring the processing accuracy.
