Description

Technical Field

[0001] The utility model belongs to the technical field of shaft part processing, and particularly belongs to an angle gauge for shaft parts. Background Technique

[0002] Shaft parts are one of the common typical parts in machines. They are mainly used to support transmission parts, transmit torque and bear loads. Among them, the shaft parts (such as camshafts, crankshafts) arranged in engines have special requirements for the installation angles of the accessories on the shafts, and they need to be accurately installed in place to ensure the normal operation of the engines.

[0003] Taking the camshaft as an example, as Figure 1 and 2 shown, a hexagonal kit 18 is fixedly sleeved on the head end of the shaft part 16, and a positioning groove 13 is arranged at the tail end. The hexagonal kit 18 facilitates the positioning and placement of the shaft part 16 during the subsequent assembly process and facilitates the use of tools (such as wrenches) to engage with the hexagonal kit 18 to rotate the shaft part 16. According to the drawing requirements, the hexagonal kit 18 at the head end and the positioning groove 13 at the tail end need to be perpendicular (angle tolerance ±2°). The two are relatively far apart and are not easy to visually measure. The conventional measurement method is to use a coordinate measuring machine to separately collect the coordinate points of the positions of the positioning groove 13 and the hexagonal kit 18 to form a reference plane and then evaluate. The detection efficiency is very low and cannot meet the requirements of batch production detection every day. Content of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide an angle gauge for shaft parts. The shaft part is clamped by the cooperation of the first center and the second center. The positioning key on the first center is inserted into the positioning groove at the end of the shaft part to realize the fixed placement of the shaft part. Then, the clamping plate is moved upward so that the clamping groove is engaged with the hexagonal kit. If the clamping groove can be smoothly engaged with the hexagonal kit, the angle between the hexagonal kit and the positioning groove meets the requirements. The structure of this application is simple, the operation is simple, there is no need to collect points and quantify for detection multiple times, the detection efficiency is high, and the use cost is low.

[0024] The following will be combined with Figures 1 - 3 to make a detailed description of the present utility model.

[0025] Embodiment

[0026] An angle gauge for shaft parts includes a base plate 1. A fixed seat 20 and a tailstock 11 are oppositely arranged on the base plate 1. A first center 12 is arranged on the tailstock 11, and a second center 19 that cooperates with the first center 12 to clamp the shaft part 16 is arranged on the fixed seat 20. An installation seat 4 is arranged between the fixed seat 20 and the tailstock 11. A first guide rail 17 is vertically arranged on the installation seat 4. A moving seat 7 is slidably connected to the first guide rail 17. A clamping plate 5 is arranged on the moving seat 7. A clamping groove 21 adapted to the hexagonal kit 18 on the shaft part 16 is arranged on the clamping plate 5. A positioning key 14 is arranged on the first center 12, and a positioning groove 13 that cooperates with the positioning key 14 is arranged at the end of the shaft part 16.

[0027] The shaft part is clamped by the cooperation of the first center 12 and the second center 19. The positioning key 14 on the first center 12 is inserted into the positioning groove 13 at the end of the shaft part 16 to realize the fixed placement of the shaft part 16. Then, the clamping plate 5 is moved upward to make the clamping groove 21 engage with the hexagonal kit 18. If the clamping groove 21 can be smoothly inserted into the hexagonal kit 18, the angle between the hexagonal kit 18 and the positioning groove 13 meets the requirements. The first guide rail 17 enables the clamping plate 5 to move vertically up and down to facilitate the detection of the hexagonal kit 18.

[0028] The first center 12 movably penetrates through the tailstock 11. A guiding groove 23 is axially formed on the first center 12, and a guiding key 22 that cooperates with the guiding groove 23 is arranged on the tailstock 11. An elastic component 10 for driving the first center 12 to abut against the shaft part 16 is installed on the tailstock 11. The cooperation of the guiding groove 23 and the guiding key 22 limits the first center 12 to prevent the first center 12 from rotating. When the shaft part 16 is fixedly placed, the first center 12 is pushed backward so that the shaft part 16 can be placed between the first center 12 and the second center 19. After releasing the first center 12, the elastic component 10 can abut the first center 12 against the shaft part 16 to ensure the stable clamping of the shaft part 16. The setting of the elastic component 10 avoids the need to adjust the position of the tailstock 11 when placing the shaft part 16 and reduces the wear of the tailstock 11.

[0029] As Figure 3 shown, the elastic component 10 includes a housing 1002. A fixing screw 1003 threadedly connected to the tailstock 11 penetrates through the housing 1002, and a spring 1001 abutting against the end of the first center 12 is arranged in the housing 1002. The housing 1002 is detachably connected to the tailstock 11 through the fixing screw 1003, which is convenient for installation and disassembly. The spring 1001 abuts against the end face of the first center 12 and drives the first center 12 to move towards the second center 19, so that the first center 12 abuts tightly against the shaft part 16.

[0030] A second guide rail 2 arranged axially along the first center point 12 is provided on the bottom plate 1. The tailstock 11 is slidably arranged on the second guide rail 2. A threaded rod 9 that abuts against the side wall of the second guide rail 2 is provided on the side wall of the tailstock 11. The threaded rod 9 is connected to a handle 8. The tailstock 11 can be moved and adjusted in position on the second guide rail 2, so that shaft parts 16 of different lengths can be clamped and fixed. Among them, by rotating the threaded rod 9 with the handle 8, the end of the threaded rod 9 is tightened against the side wall of the second guide rail 2, thereby realizing the locking of the tailstock 11.

[0031] A support plate 15 is slidably arranged on the second guide rail 2, and a V-shaped groove is provided on the support plate 15. The support plate 15 can play a preliminary supporting role when placing the shaft part 16, facilitating the first center point 12 to abut and clamp the shaft part 16, and avoiding the situation that the shaft part 16 drops and collides and damages the product due to the too long cantilever of the shaft part 16 when being taken.

[0032] A third guide rail 3 arranged axially along the first center point 12 is provided on the bottom plate 1. The mounting seat 4 is slidably connected to the third guide rail 3. The clamping plate 5 can be adjusted in position according to the position of the hexagon kit 18 on the shaft part 16, so as to adapt to the detection of various shaft parts 16. Among them, the mounting seat 4 can use the locking mechanism of the tailstock 11 to lock the position after moving, and the mounting seat 4 can also not use the locking mechanism and still realize the detection function of the clamping plate 5.

[0033] Both the first guide rail 17 and the third guide rail 3 are provided with two, and are located on both sides of the shaft part 16. After both the first guide rail 17 and the third guide rail 3 are provided with two, the stability of the lateral movement of the mounting seat 4 and the stability of the up and down movement of the moving seat 7 can be increased, and the deflection of the mounting seat 4 and the moving seat 7 can be avoided, which affects the detection accuracy of the clamping plate 5.

[0034] A buffer pad 6 is provided on the upper surface of the mounting seat 4. The buffer pad 6 can be a rubber pad. After the clamping plate 5 finishes the detection, the moving seat 7 is directly released, and the moving seat 7 automatically falls back to its original position, reducing the falling impact force of the moving seat 7 and avoiding damage to the moving seat 7.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
