[0003] When finishing the inner hole of the sleeve (i.e., the shaft hole on the shell) of the brake basic device (hereinafter referred to as the brake device) of the train brake system, special tooling is required to fix the brake device. Utility Model Content
[0004] The utility model aims to provide a tool for fine turning the inner hole of a brake basic device sleeve of a train brake system, which has the effect of fixing the brake device.
[0005] The above technical purpose of the present utility model is achieved through the following technical scheme: it includes a base and a positioning cylinder vertically arranged on the base, the diameter of the positioning cylinder is the same as the inner diameter of the connecting cylinder, and the base is symmetrically provided with fixing parts for fixing the connecting shaft, and the two fixing parts are respectively located on both sides of the fixing cylinder.
[0006] The present invention is further configured as follows: the fixing member includes a fixing block and a fixing hole opened on the fixing block; a fixing cylinder is symmetrically provided on the base along the vertical direction; the inner wall of the fixing cylinder is threadedly connected to a fixing rod; the fixing rod can movably pass through the fixing hole; the bottom of the fixing block can abut against the top of the fixing cylinder; a rotating block is provided on the top of the fixing rod; the bottom of the rotating block can abut against the fixing block; when the fixing block abuts against the fixing cylinder, the fixing block can abut against the connecting shaft.
[0007] The present invention is further configured as follows: positioning rods are symmetrically provided on the base along the vertical direction, and when one end of the fixing block abuts against the connecting shaft, the other end of the fixing block abuts against the top of the positioning rod.
[0008] The present invention is further configured as follows: the fixing block is in the shape of an elongated strip.

[0013] The present invention is further configured such that when the fixing rod contacts the end of the fixing hole away from the connecting shaft, the fixing block movably fits against the outer wall of the shell.
[0014] The beneficial effects of the utility model are:
[0015] 1. By setting the positioning cylinder and the fixing part, when it is necessary to fine-turn the shaft hole of the brake device, first put the end of the brake device away from the shaft hole, that is, the connecting cylinder, downward on the positioning cylinder, so that the inner wall of the connecting cylinder fits the outer wall of the positioning cylinder, and then rotate the shell to make the connecting shafts on both sides of the shell close to the fixing part, and then fix the connecting shafts on both sides of the shell by the fixing part. At this time, one end of the shaft hole on the shell faces upward, and fine-turning can be performed; by setting the positioning cylinder and the fixing part, the positioning cylinder positions the brake device as a whole, so that the shaft hole on the shell faces upward, and then the connecting shafts on both sides are fixed by the fixing part, thereby realizing the fixation of the brake device. At the same time, there is a certain distance between the connecting shaft and the end face of the shell, ensuring that one end of the shaft hole to be processed on the shell is exposed as a whole under the fine-turning equipment, which is convenient for subsequent fine-turning of the shaft hole.
[0016] 2. By setting a fixing block, a fixing hole and a fixing cylinder, etc., after the brake device is put downward on the positioning cylinder, the shell is rotated so that the connecting shafts on both sides of the shell are facing the adjacent fixing cylinders, and then the fixing block is rotated so that the bottom of the fixing block is in contact with the top of the connecting shaft, and then the rotating block is rotated to move the fixing rod downward along the fixing cylinder until the rotating block contacts the top of the fixing block, and the fixing block is clamped between the fixing cylinder and the rotating block. At this time, one end of the fixing block also contacts the connecting shaft, and the connecting shaft is pressed between the base and the fixing block, thereby achieving the fixation of the brake device. The structure is simple and the operation is convenient.
[0017] 3. By setting a positioning rod, when the connecting shaft is fixed, one end of the fixed block contacts the connecting shaft, and the other end of the fixed block contacts the top of the positioning rod. Therefore, when the rotating block is rotated to clamp the fixed block, the two ends of the fixed block apply downward force to the connecting shaft and the positioning rod respectively, and at the same time, the connecting shaft and the positioning rod apply upward reaction force to the fixed block, so that the two ends of the fixed block can be evenly stressed, avoiding the situation where only one end of the fixed block close to the connecting shaft is subjected to force, causing the fixed block to tilt slightly, thereby reducing the contact area between the fixed block and the connecting shaft, affecting the fixing effect of the connecting shaft.

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0024] The utility model provides a train brake system brake basic device sleeve inner hole finishing tooling, such as Figures 1 to 3 As shown, it includes a base 1 and a positioning cylinder 2 vertically arranged on the base 1, the diameter of the positioning cylinder 2 is the same as the inner diameter of the connecting cylinder 11, and the base 1 is symmetrically provided with fixing parts 3 for fixing the connecting shaft 12, and the two fixing parts 3 are respectively located on both sides of the fixing cylinder 4.
[0025] Furthermore, the fixing member 3 includes a fixing block 3a and a fixing hole 3b opened on the fixing block 3a. The base 1 is symmetrically provided with a fixing cylinder 4 in the vertical direction. The inner wall of the fixing cylinder 4 is threadedly connected with a fixing rod 5. The fixing rod 5 can move through the fixing hole 3b. The bottom of the fixing block 3a can abut against the top of the fixing cylinder 4. The top of the fixing rod 5 is provided with a rotating block 6. The bottom of the rotating block 6 can abut against the fixed block 3a. When the fixed block 3a abuts against the fixed cylinder 4, the fixed block 3a can abut against the connecting shaft 12.
[0026] Furthermore, positioning rods 7 are symmetrically provided on the base 1 along the vertical direction. When one end of the fixing block 3 a contacts the connecting shaft 12 , the other end of the fixing block 3 a contacts the top of the positioning rod 7 .
[0027] Furthermore, the fixing block 3a is in the shape of an elongated strip.
[0028] Furthermore, the fixing hole 3b is in the shape of an elongated strip.
[0029] Furthermore, the rotating block 6 is in the shape of an elongated strip.
[0030] Furthermore, an elastic wear-resistant layer 8 is provided on the bottom surface of the fixing block 3a.
[0031] Furthermore, the height of the positioning tube 2 is greater than the height of the connecting tube 11 .
[0032] Furthermore, when the fixing rod 5 contacts the end of the fixing hole 3 b away from the connecting shaft 12 , the fixing block 3 a movably fits against the outer wall of the housing 9 .
[0033] When it is necessary to fine-turn the shaft hole of the brake device, first, the end of the brake device away from the shaft hole, that is, the connecting tube 11, is downwardly sleeved on the positioning tube 2 so that the inner wall of the connecting tube 11 fits against the outer wall of the positioning tube 2, and then the housing 9 is rotated so that the connecting shafts 12 on both sides of the housing 9 are facing the adjacent fixed tubes 4, and then the fixed block 3a is rotated so that the bottom of the fixed block 3a fits against the top of the connecting shaft 12, and then the fixed block 3a is pushed along the fixing hole 3b so that one end of the fixed block 3a contacts the outer wall of the housing 9, and then the rotating block 6 is rotated to move the fixing rod 5 downward along the fixed tube 4 until the rotating block 6 contacts the top of the fixed block 3a, clamping the fixed block 3a between the fixed tube 4 and the rotating block 6. At this time, one end of the fixing block 3a also contacts the connecting shaft 12, pressing the connecting shaft 12 between the base 1 and the fixing block 3a, and the other end of the fixing block 3a contacts the top of the positioning rod 7. At this time, one end of the shaft hole on the shell 9 faces upward, and fine turning can be performed; by setting the positioning cylinder 2 and the fixing block 3a, the positioning cylinder 2 positions the brake device as a whole so that the shaft hole on the shell 9 faces upward, and then the connecting shafts 12 on both sides are fixed by the fixing block 3a, thereby achieving the fixation of the brake device. At the same time, there is a certain distance between the connecting shaft 12 and the end face of the shell 9, ensuring that one end of the shaft hole to be processed on the shell 9 is exposed as a whole under the fine turning equipment, which is convenient for subsequent fine turning of the shaft hole.
[0034] By providing the fixing block 3a, the fixing hole 3b and the fixing cylinder 4, etc., after the brake device is downwardly sleeved on the positioning cylinder 2, the housing 9 is rotated so that the connecting shafts 12 on both sides of the housing 9 are facing the adjacent fixing cylinders 4, and then the fixing block 3a is rotated so that the bottom of the fixing block 3a is in contact with the top of the connecting shaft 12, and then the rotating block 6 is rotated to move the fixing rod 5 downward along the fixing cylinder 4 until the rotating block 6 contacts the top of the fixing block 3a, clamping the fixing block 3a between the fixing cylinder 4 and the rotating block 6. At this time, one end of the fixing block 3a also contacts the connecting shaft 12, pressing the connecting shaft 12 between the base 1 and the fixing block 3a, thereby achieving the fixation of the brake device, with a simple structure and easy operation.
[0035] By setting the positioning rod 7, when the connecting shaft 12 is fixed, one end of the fixed block 3a contacts the connecting shaft 12, and the other end of the fixed block 3a contacts the top of the positioning rod 7. Therefore, when the rotating block 6 is rotated to clamp the fixed block 3a, the two ends of the fixed block 3a respectively apply a downward force to the connecting shaft 12 and the positioning rod 7. At the same time, the connecting shaft 12 and the positioning rod 7 apply an upward reaction force to the fixed block 3a, so that the two ends of the fixed block 3a can be evenly stressed, avoiding the fixed block 3a being slightly tilted when only the end of the fixed block 3a close to the connecting shaft 12 is subjected to the force, thereby reducing the contact area between the fixed block 3a and the connecting shaft 12, affecting the fixing effect of the connecting shaft 12.
[0036] By setting the fixing block 3a as a long strip, it is convenient for workers to directly judge the position of the fixing block 3a. When the braking device needs to be fixed, the fixing block 3a is rotated until it contacts the connecting shaft 12 and the positioning rod 7. After the processing is completed, the fixing block 3a is rotated to separate the fixing block 3a from the connecting shaft 12.
[0037] By setting the fixing hole 3b to be long and narrow, it is convenient to push the fixing block 3a to separate the fixing block 3a from the connecting shaft 12. At the same time, the fixing block 3a can be made to contact the shell 9, thereby increasing the contact area between the fixing block 3a and the connecting shaft 12 and increasing the fixing effect of the braking device.
[0038] By configuring the rotating block 6 to be in a long strip shape, it is convenient for a worker to directly rotate the rotating block 6 , and the contact area between the rotating block 6 and the fixed block 3 a can also be increased.
[0039] By providing the elastic wear-resistant layer, the elastic deformation of the elastic wear-resistant layer can enhance the fixing effect of the fixing block on the connecting shaft.
[0040] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
[0041] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
