DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] In the technical scheme, a lathe for processing a brake pump housing comprises a lathe body 1 and a chuck 2. The chuck 2 is rotatably mounted in the inner cavity of the lathe body 1. A clamping mechanism 3 is mounted on the side wall of the chuck 2. A brake pump housing 4 is clamped and mounted in the clamping mechanism 3.

[0023] The side wall of the chuck 2 is slidably mounted with a claw 5, and the clamping mechanism 3 is mounted on the side wall of the claw 5. The clamping mechanism 3 includes a main clamping plate 31, a secondary clamping plate 32, a positioning block 33, a positioning groove 34, a top plate 35, a bolt 36 and a pressure block 37. The main clamping plate 31 and the secondary clamping plate 32 are respectively mounted on the side walls of the two clamping jaws 5. The side wall of the main clamping plate 31 is mounted with a positioning block 33. The side wall of the positioning block 33 is provided with a positioning groove 34. The brake pump housing 4 is placed in the positioning groove 34. The side wall of the secondary clamping plate 32 is screwed with a bolt 36. There are at least two bolts 36. The ends of the two bolts 36 are respectively mounted with a pressure block 37 and a top plate 35. Both the pressure block 37 and the top plate 35 can fit with the side wall of the brake pump housing 4.

[0024] In this technical solution, when clamping the brake pump housing 4, the brake pump housing 4 is first placed in the positioning groove 34 on the main clamping plate 31, and then the two-way electrically controlled telescopic rod 6 in the chuck 2 is retracted to make the main clamping plate 31 and the auxiliary clamping plate 32 close to the middle, and then the bolt 36 is rotated to make the pressure block 37 and the top plate 35 fit with the side wall of the brake pump housing 4 to complete the fixing of the brake pump housing 4. After the fixing is completed, the turning tool can be moved to the vicinity of the brake pump housing 4 according to the position of the brake pump housing 4, and then the lathe is started, the chuck 2 drives the clamping mechanism 3 and the brake pump housing 4 to rotate, and then the brake pump housing 4 can be trimmed by the turning tool.

[0025] In some technical solutions, a bidirectional electrically-controlled telescopic rod 6 is installed in the inner cavity of the chuck 2, and the bidirectional electrically-controlled telescopic rod 6 is electrically connected to an external power supply. A slide groove 7 is provided on the side wall of the chuck 2, and the claw 5 is slidably installed in the slide groove 7. The output ends on both sides of the bidirectional electrically-controlled telescopic rod 6 are respectively connected to the two claws 5.

[0026] In this technical solution, the bidirectional electrically-controlled telescopic rod 6 is arranged in the middle of the chuck 2, so when the bidirectional electrically-controlled telescopic rod 6 is controlled to retract or push out, the two claws 5 move synchronously to avoid the situation where the two claws 5 cannot be clamped due to single movement.

[0027] In some technical solutions, a clearance hole 8 is opened on the side wall of the auxiliary clamping plate 32, a threaded hole 9 is opened on the inner side wall of the clearance hole 8, a bolt 36 is screwed into the threaded hole 9, and a rubber plug 10 is inserted and installed in the clearance hole 8.

[0028] In this technical solution, the bolt 36 is arranged in the clearance hole 8 and does not protrude from the clearance hole 8. This can prevent the protruding bolt 36 from scratching the staff when the chuck 2 rotates. At the same time, the rubber plug 10 can prevent debris from entering the clearance hole 8 to avoid affecting the adjustment of the bolt 36.

[0029] In some technical solutions, a telescopic cylinder 11 is installed on the side wall of the auxiliary clamping plate 32 . The telescopic cylinder 11 is sleeved on the outside of the bolt 36 . A spring 12 is installed in the inner cavity of the telescopic cylinder 11 .

[0030] In this technical solution, the cut chips can be blocked by the telescopic tube 11 to prevent the chips from being brought into the threaded hole 9 when the bolt 36 is rotated, thereby preventing the bolt 36 from being unable to rotate.

[0031] In some technical solutions, the bolt 36 includes a screw rod 361, a screw head 362, a connecting groove 363 and a sliding block 364. A connecting groove 363 is provided at the end of the screw rod 361, and a sliding block 364 is slidably installed in the connecting groove 363. The cross-sections of the connecting groove 363 and the sliding block 364 are both square, and a screw head 362 is installed at one end of the sliding block 364 located outside the connecting groove 363.

[0032] In this technical solution, the cross-section of the clearance hole 8 is the same as that of the screw head 362, both of which are hexagonal. When the bolt 36 needs to be rotated to adjust the pressure block 37 and the top plate 35, the screw head 362 needs to be pulled to expose it from the clearance hole 8, and then the screw head 362 is rotated to drive the screw rod 361 to rotate through the sliding block 364. After the rotation is completed, the screw head 362 is sunk back into the clearance hole 8 to prevent the bolt 36 from rotating autonomously and causing the brake pump housing 4 to loosen.

[0033] In some technical solutions, sealing gaskets 13 are fitted on both ends of the telescopic cylinder 11 .

[0034] Working principle: when clamping the brake pump housing 4, first place the brake pump housing 4 in the positioning groove 34 on the main clamping plate 31, and then retract the two-way electrically controlled telescopic rod 6 in the chuck 2 to make the main clamping plate 31 and the auxiliary clamping plate 32 close to the middle, and then screw the bolt 36 to make the pressure block 37 and the top plate 35 fit with the side wall of the brake pump housing 4 to complete the fixation of the brake pump housing 4. After the fixation is completed, the turning tool can be moved to the vicinity of the brake pump housing 4 according to the position of the brake pump housing 4, and then the lathe is started, the chuck 2 drives the clamping mechanism 3 and the brake pump housing 4 to rotate, and then the brake pump housing 4 can be trimmed by the turning tool.
