Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a tail bracket device of a bearing processing milling machine. Background Art

[0002] The slender shaft of the bearing is a long and thin shaft. Due to its long length, when it is processed by a milling machine, the tail of the slender shaft is often suspended in the air, making it difficult to control the stability during processing and difficult to process. Therefore, when processing slender shafts, the milling machine is often equipped with a tail support device to firmly support and fix the slender shaft for easy processing.

[0003] At present, the tail support device of the slender shaft is often a chuck structure. During operation, the worker needs to first insert the slender shaft horizontally from the center of the chuck to ensure that the chuck and the slender shaft maintain the same axis. Although this method can also play a role in fixing and supporting the tail of the slender shaft, due to the long length of the slender shaft, the method of extending it from the side and fixing it requires a high margin space on the side of the milling machine, which is inconvenient to implement. Based on this, the inventor now proposes an improved tail support device. Utility Model Content

DETAILED DESCRIPTION

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0037] The utility model embodiment specifically provides a bearing processing milling machine tail bracket device, please refer to Figure 1 , including a milling machine body 1 and a supporting assembly 4.

[0038] Among them, the milling machine body 1 includes a sliding platform 11 installed on the top, and a slidable slide 2 is arranged on the surface of the sliding platform 11. During daily use, the position of the slide 2 is adjusted by operating the sliding platform 11, so that the slide 2 can be slid and adjusted along the length direction of the sliding platform 2. A slender shaft 3 is arranged above the slide 2, and a support assembly 4 is fixed on the surface of the slide 2. The tail of the slender shaft 3 is detachably connected to the support assembly 4, so that the head of the slender shaft 3 can be punched and milled, and the tail support assembly 4 is fixed and removed after processing.

[0039] For details, please refer to Figure 1 and Figure 2 The support assembly 4 includes a support 41, a pressure seat 42, a clamping block 43, a driving assembly 44, a side pressure plate 45 and a side clamping assembly 46. The bottom of the support 41 is fixedly connected to the slide seat 2, and the bottom of the pressure seat 42 is in sliding contact with the support 41. There are two clamping blocks 43, which are symmetrically installed on the pressure seat 42 and the clamping blocks 43 respectively. The adjacent surfaces of the clamping blocks 43 are clamped with the slender shaft 3, so that when the pressure seat 42 slides up and down on the support 41, it can drive the top clamping block 43 and the bottom clamping block 43 to move closer to or away from each other, so as to facilitate the clamping and release of the slender shaft 3.

[0040] The outer end of the pressure seat 42 is fixed to the driving component 44, so that the pressure seat 42 can be driven to move upward by the driving component 44, so that the clamping block 43 at the bottom of the pressure seat 42 can move upward. Therefore, when the slender shaft 3 is processed and placed, it only needs to be placed horizontally at the bottom of the clamping block 43, and then placed on the clamping block 43 on the support 41, and then the upper clamping block 43 can be clamped, thereby facilitating the lateral translation fixed support placement and removal of the slender shaft 3, improving the convenience of use, and requiring a small installation space.

[0041] Among them, the side pressure plate 45 is fixedly installed on the left and right sides of the pressure seat 42, the side clamp assembly 46 is arranged in the support 41, and the upper end and inner end of the side clamp assembly 46 are respectively in contact with the side pressure plate 45 and the slender shaft 3, so as to clamp the left and right sides of the slender shaft 3 through the side clamp assembly 46 to improve the fixed support effect.

[0042] For further information, please refer to Figure 3 The clamping block 43 includes a block body 431, a fitting groove 432 and an anti-slip strip 433. A fitting groove 432 is provided on one side of the block body 431 close to the slender shaft 3. The shape of the fitting groove 432 is preferably a trapezoidal structure to facilitate fitting with the slender shaft 3. The anti-slip strip 433 is arranged and fixed on the inner wall of the fitting groove 432. The fitting groove 432 is clamped with the slender shaft 3 through the anti-slip strip 433, so that when the slender shaft 3 is placed, the anti-slip strip 433 can apply force to contact the slender shaft 3 to clamp and fix the slender shaft 3.

[0043] During implementation, the number of anti-slip strips 433 is set at two or more, and the anti-slip strips 433 as a whole remain parallel to the length direction of the slender shaft 3 to perform anti-slip treatment on the circumferential rotation of the slender shaft 3, so as to avoid the slender shaft 3 from rotating during processing and improve the supporting fixing force.

[0044] Among them, the pressure seat 42 includes a pressure block 421 and a connecting block 422. The connecting block 422 is fixed on the outer top of the pressure block 421. The end of the connecting block 422 away from the pressure block 421 is connected to the driving component 44, so that the pressure block 421 can be moved up and down by the driving component 44. An axial groove 411 with an open top is opened in the middle of the support 41. The bottom of the pressure block 421 is in sliding contact with the axial groove 411, so that the pressure block 421 can drive the block 431 to slide downward or linearly downward, so that the two upper and lower spaced blocks 431 can approach or move away from each other.

[0045] During implementation, the block 431 is symmetrically fixed on the pressure block 421 and the bottom of the shaft groove 411. When the slender shaft 3 needs to be taken out, the driving component 44 drives the pressure block 421 and the block 431 to move out of the shaft groove 411, and then the slender shaft 3 can be moved out of the shaft groove 411, and the new slender shaft 3 is placed in the shaft groove 411, and then the pressure block 421 drives the block 431 to move down and press the slender shaft 3, so as to realize the tail support and fixation of the slender shaft 3.

[0046] Furthermore, the driving assembly 44 includes a sliding rod 441, a sliding table 442, a screw rod 443 and a rotary handle 444. The bottom of the sliding rod 441 is vertically fixed to the sliding seat 2, and both ends of the sliding table 442 are slidably installed on the sliding rod 441. The outer wall of the sliding table 442 is fixedly connected to the connecting block 422, the bottom of the screw rod 443 is rotatably connected to the sliding seat 2, and the outer side of the screw rod 443 is threadedly connected to the sliding table 442, and the rotary handle 444 is fixedly installed on the top of the screw rod 443. By rotating the rotary handle 444, the sliding table 442 is driven to move up or down along the sliding rod 441, thereby driving the pressure block 421 to move up and down in a straight line to meet the needs of use.

[0047] For further information, please refer to Figure 3 and Figure 4 The support 41 is provided with a mounting groove 412 and a slot 413 which are interconnected. The inner side of the mounting groove 412 is connected to the shaft groove 411. The side pressure plate 45 is fixed to the outer wall of the pressure block 421, and the bottom of the side pressure plate 45 is plugged into the slot 413, so that when the pressure plate 45 moves up and down, it can drive the side pressure plate 45 and the slot 413 to be plugged in or separated. The side clamping assembly 46 is arranged inside the mounting groove 412, so that after the pressure plate 45 moves down, when the blocks 431 clamp the slender shaft 3 up and down, at this time, the side frame assembly 46 is clamped with the left and right sides of the slender shaft 3 through the pressure of the side pressure plate 45, thereby improving the supporting and fixing effect of the slender shaft 3.

[0048] Specifically, the side clamp assembly 46 includes a rotating frame 461, a rotating shaft 462, a pressure rod 463 and an anti-skid plate 464. The rotating shaft 462 is fixedly installed at the front and rear ends of the rotating frame 461. The rotating frame 461 is rotatably connected to the mounting groove 412 through the rotating shaft 462. The right end of the pressure rod 463 is vertically fixed to the rotating frame 461. The anti-skid plate 464 is fixed to the right end of the rotating frame 461. The rotating frame 461 is in contact with the slender shaft 3 through the anti-skid plate 464, so that when the rotating frame 461 rotates inward, the anti-skid plate 464 clamps the slender shaft 3 tightly to increase the supporting and fixing force of the slender shaft 3.

[0049] During implementation, the left end of the pressure rod 463 extends into the slot 413, and the bottom of the side pressure plate 45 is inserted into the slot 413 and pressed against the pressure rod 463, so that the side pressure 45 applies force to the pressure rod 463 after the pressure block 421 moves down synchronously, so that the rotating frame 461 can rotate with the rotating shaft 462 as the fulcrum, thereby making the anti-slip plates 464 at both ends rotate close to each other to clamp the slender shaft 3.

[0050] The height direction of the anti-slip plate 464 is kept parallel to the length direction of the slender shaft 3, and the anti-slip plate 464 is arranged along the length direction of the rotating frame 461 to provide anti-slip support for the sliding of the slender shaft 3 in the length direction, so as to increase the placement stability effect.

[0051] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
