Description

TECHNICAL FIELD

[0001] The utility model relates to the clutch detection field especially relates to a clutch detection frock. BACKGROUND

[0002] After clutch production, the clutch is detected to ensure that the product meets the quality standards and performance requirements. During the detection process, the fixture and the installation mechanism are required to fix the to-be-detected clutch on the clutch detection table. The fixture and the installation mechanism need to accurately install the clutch to ensure the stability of the clutch during the test process and the coaxiality with the load shaft, thereby ensuring the accuracy of the test results. The existing clutch detection frock usually needs to install the to-be-detected clutch on the detection frock in advance, and then fix it on the detection table from the side for testing. This method takes a long time to install, the labor intensity of the operator is large, and the detection efficiency is low. Some clutch detection tables with a turnover function use manual turnover of the clutch. Due to the different strength and operation methods of each person, the turnover angle and force of the clutch are inconsistent, which cannot guarantee the coaxiality of the to-be-detected clutch with the load shaft after turnover, affects the butt joint with the load shaft, takes a long time to adjust, and affects the detection efficiency and detection accuracy.

[0014] The technical scheme of the utility model will be further described below with reference to the drawings.

[0015] As shown in the figure, the utility model discloses a kind of clutch detection tool, including mounting clamp 1, turnover mechanism 2 support 3, driving mechanism 4 and limiting mechanism.Quick positioning and fixed to-be-measured clutch is used to mounting clamp 1, support surface 101 is used to place to-be-measured clutch, and positioning mechanism is equipped at the center of support surface, and positioning mechanism is detachable, and can be selected according to the model of to-be-measured clutch, and corresponding positioning mechanism is selected, and compatibility is strong. Center of positioning mechanism is equipped with the mounting shaft 103 adapted to to-be-measured clutch, and a plurality of mounting holes 104 are equipped around mounting shaft, and to-be-measured clutch is fixed on support surface by bolt connection, positioning mechanism. The outer part of positioning mechanism is equipped with three clamping cylinders 102, when to-be-measured clutch is inserted into mounting shaft, to-be-measured clutch will be close to support surface under the action of gravity, clamping cylinder is automatically clamped, and clutch is firmly installed on platform, to ensure that clutch position remains fixed during turnover, to prevent the test result from being affected due to loosening;Clamping cylinder is automatically clamped, and the clamping of clutch can be quickly completed, to improve detection efficiency. Second positioning hole 105 for mounting clamp and turnover mechanism assembly positioning and second assembly hole 106 for mounting clamp and turnover mechanism assembly fixation are also symmetrically equipped on support surface.

[0016] Turnover mechanism 2 includes turnover platform 201, first positioning hole 202 and first assembly hole 203. Turnover platform 201 is square, and the middle part is hollow for assembling mounting clamp, and first positioning hole 202 is equipped corresponding to second positioning hole on mounting clamp, and first positioning hole has 2, and can also have multiple, and positioning is realized using positioning pin. First assembly hole 203 is equipped corresponding to second assembly hole on mounting clamp, and first assembly hole is equipped with 5, and is annularly distributed, and the number of holes can be adjusted according to demand, as long as fixed connection of turnover mechanism and mounting clamp can be realized. The support 3 is used to erect turnover platform, and is in the shape of U opening upwards, and concentric bearing 301 is equipped at the top of both sides, and rotating shaft is erected in concentric bearing, and turnover platform rotates along with rotating shaft, and concentric bearing makes turnover mechanism stable during turnover, and deviation does not occur. Turnover mechanism rotates 90 ° with to-be-measured clutch to to-be-measured position, and docking load shaft can start detection.

[0017] The limiting mechanism is used to ensure that the center position of the clutch to be tested is not deviated after being turned over. The first limiting block 5 is used to limit the turning angle to be less than 90 degrees. During the detection process, the load shaft drives the clutch to rotate at high speed to generate a force. The first limiting block can ensure that the turning platform remains stable and does not deviate in angle. The first limiting block is fixed at the bottom of the support 3 and has an L shape. Preferably, there are two first limiting blocks to balance the force on both sides. The vertical surface and the horizontal surface of the first limiting block are fixed on the support. An equal height block is arranged on the vertical surface of the first limiting block. One end of the equal height block is screwed into the first limiting block. The first buffer 7 is horizontally fixed on the vertical surface of the first limiting block to avoid hard impact when the turning platform is turned to the position to be tested. The position of the clutch to be tested is deviated, and the turning platform is damaged. When the turning platform is rotated to the standby position, hard impact and excessive turning may occur. Therefore, the second limiting block 6 is fixedly connected to the inner side of the support. Correspondingly, the second buffer 8 and the equal height block are arranged vertically upward on the second limiting block.

[0018] The driving mechanism 4 is used to drive the turning mechanism to rotate and includes a locking cylinder 401 and a connecting rod 402 connected with the output end of the locking cylinder. After being turned to the specified position, the cylinder is locked to ensure stability during the detection process and prevent the turning mechanism from deviating in angle under the action of the force of the load shaft.

[0019] The detection tool integrates the mounting clamp and the turning mechanism. During detection, the preparation step of connecting the clutch to be tested with the mounting clamp and then fixing it on the detection table is omitted, which can greatly shorten the preparation time for single detection. In large-scale clutch testing tasks, a large amount of time is saved, and the overall detection efficiency is improved. The locking cylinder drives the turning mechanism to rotate to ensure that the detection conditions are consistent each time, reduce the interference of factors such as angle deviation and installation position change caused by manual turning on the detection result, set the limiting mechanism to effectively avoid the influence of inertial force generated by mechanical rotation on the center position of the clutch to be tested, quickly realize the butt joint of the clutch to be tested and the load shaft, and save the adjustment time.
