Description

Technical Field

[0001] The utility model relates to the technical field of shift fork production, in particular to a detection device for a shift fork of a vehicle transmission. Background Art

[0002] The shift fork is generally used in the transmission to shift the gear on the shaft to cooperate with another gear to obtain another speed, thereby achieving speed change. The shift fork generally includes a rear handle and a fork foot. The rear handle has an axial hole that is sleeved on the sliding shaft and slides with the sliding shaft. A circular groove is formed on the inner side of the fork foot, and the two sides of the groove are divided into fork feet. The side of the fork foot perpendicular to the axis of the shaft hole is the shift surface, which is used to shift the gear.

[0003] Authorization announcement No. CN218066182U discloses a fork position measuring instrument for a shift fork, including a shift fork, a fixing mechanism and a measuring mechanism. The utility model is provided with fixing mechanisms on the back and front of the shift fork, and measuring mechanisms for measuring the two fork legs are provided on the two fork legs of the shift fork. When testing, the shift fork is placed with its opening facing upward, the back of the shift fork is fixed on the fixing piece, the long fork leg is fixed on the first measuring piece, and the clamping piece is pressed on the front of the shift fork. At this time, the second measuring piece is slid to measure the short fork leg. If the short fork leg can be inserted into the second measuring piece, it means that the position of the two fork legs is good. Conversely, if the short fork leg cannot be inserted into the second measuring piece, it means that the position of the two fork legs is not good.

[0004] However, the above-mentioned detection equipment does not have a certain error tolerance. In the manufacturing industry, it is common to allow errors in workpieces. Because error-free detection will lead to increased costs, increased technical difficulty, reduced efficiency, and limited practical applications, we should reasonably set measurement accuracy requirements according to specific needs and take corresponding measures to ensure the accuracy and reliability of the measurement results.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 4 As shown, a vehicle transmission shift fork detection device includes a base 2, a fixing mechanism provided on the top of the base 2 for pressing the horizontal plate of the shift fork body 1, and a measuring mechanism 1 and a measuring mechanism 2 provided at the two fork legs of the shift fork body 1 for measuring the two fork legs respectively;

[0026] Among them, the measuring mechanism 1 is used to engage the short fork leg 11, and the measuring mechanism 2 includes a measuring platform 4 fixedly connected to the top of the fork body 1, a square groove 41 opened on the top of the measuring platform 4, and a measuring pin 42 that can slide horizontally along the square groove 41. The measuring pin 42 is used to detect the long fork leg 12. A horizontal limit component is provided between the square groove 41 and the measuring pin 42. The measuring pin 42 is a U-shaped plate. The open end of the measuring pin 42 is set toward the long fork leg 12. The measuring pin 42 is horizontally aligned with the long fork leg 12. The measuring pin 42 can slide toward or away from the long fork leg 12. The inner sides of the two side plates of the measuring pin 42 are elastically equipped with measuring plates 45. The opposite surfaces of the two measuring plates 45 near one end of the long fork leg 12 are provided with inclined surfaces to facilitate the long fork leg 12 to slide between the two measuring plates 45. The measuring plate 45 can approach or move away from the side plate of the corresponding measuring pin 42. A warning component is provided between each measuring plate 45 and the corresponding measuring pin 42.

[0027] In some specific embodiments, such as Figure 1 As shown, in order to facilitate the pressing and fixing of the fork body 1 on the base 2, the fixing structure includes a pressing member 21. The fork body 1 is placed with the open end facing upward, and the back of the fork body 1 is in contact with the base 2. The pressing member 21 is pressed on the front of the fork body 1, which makes it convenient to measure the long fork leg 12 after the fork body 1 is fixed.

[0028] In some specific embodiments, such as Figure 1 As shown, in order to facilitate the short fork leg 11 to be able to be snapped into the slot 32, the measuring mechanism includes a support platform 3, which is fixedly arranged on the top of the base 2, and a fixing member 31 is fixedly installed on the top of the support platform 3. The side of the fixing member 31 is provided with a slot 32 for the short fork leg 11 to be inserted. The end of the short fork leg 11 can be snapped into the inside of the slot 32, which makes it easy to insert the short fork leg 11 into the slot 32 or remove the short fork leg 11 from the slot 32.

[0029] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the movement of the measuring plate 45 to both sides when the long fork leg 12 has an error, a number of telescopic rods 43 are distributed between the two side plates of the measuring pin 42 and the corresponding measuring plates 45. The function of the telescopic rods 43 is to limit the moving direction of the measuring plate 45 when the measuring plate 45 moves. A spring 44 is sleeved on the outside of each telescopic rod 43, one end of the spring 44 is connected to the measuring plate 45, and the other end is connected to the measuring pin 42. When the long fork leg 12 has an error, it can squeeze the measuring plates 45 on both sides and push them to both sides. At this time, the telescopic rods 43 contract and the springs 44 compress.

[0030] In some specific embodiments, such as Figure 4As shown, in order to facilitate the detection of whether the position of the two forks is too wide or too narrow, each set of warning components includes a height adjustment member 5 and a button 51. The two side panels of the measuring plate 45 are provided with a height adjustment member 5 that can be extended and retracted in the horizontal direction. The height adjustment member 5 is a hydraulic cylinder or other length adjustment component. The driving end of the height adjustment member 5 is provided with a button 51. A warning light 53 is also provided on the side of the measuring platform 4. The two buttons 51 can control the warning light 53 to emit light of different colors. The button 51 cooperates with the corresponding measuring plate 45. A control panel 52 for controlling the operation of the height adjustment member 5 is provided on the side of the measuring platform 4.

[0031] In some specific embodiments, such as Figure 1 As shown, in order to increase the fixing speed of the fork body 1, the clamping member 21 is a quick clamp. In some embodiments, the quick clamp can also be replaced with other clamps with clamping force similar to the quick clamp, thereby improving the stability of the fork body 1 fixed to the base 2 during measurement, facilitating press-fitting, and reducing measurement errors.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0033] Before the test, the control panel 52 is used to control the two height adjustment members 5 to extend or retract synchronously. The distance between the button 51 and the corresponding measuring plate 45 is the allowable error range. This device allows for errors, and the error range is adjustable, which makes it highly applicable.

[0034] During the test, the fork body 1 is placed with its opening facing upwards and the back of the fork body 1 placed on the base 2. The fork body 1 is pushed to insert the short fork leg 11 into the slot 32 on the fixing member 31. The pressing member 21 is pulled to fix the fork body 1 on the base 2, thereby fixing the fork body 1. At this time, the sliding measuring pin 42 is moved toward the long fork leg 12 for testing, thereby inserting the long fork leg 12 between the two measuring plates 45. If there is an error in the long fork leg 12, it will squeeze the corresponding measuring plate 45 close to the button 51. At this time, the telescopic rod 43 is moved. The long prong 12 contracts and the spring 44 compresses. During this process, if the long prong 12 can be inserted between the two measuring plates 45 and the movement of the measuring plates 45 does not touch any button 51, it means that the positions of the two prongs of the fork body 1 are good. On the contrary, when the long prong 12 is inserted between the two measuring plates 45, the warning light 53 lights up, which means that the positions of the two prongs of the fork body 1 are not good, and the two buttons 51 can control the warning light 53 to emit two colors of light. By observing the color of the light, it can be judged whether the position of the two prongs is too wide or too narrow.

[0035] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
