Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm springs, and particularly relates to a detection device for a clutch diaphragm spring. Background Technique

[0002] The diaphragm spring is an important component of the clutch. As a pressing mechanism, the diaphragm spring is radially provided with a plurality of cutting grooves to form an elastic lever. There are round holes at the ends of the cutting grooves. The fixing rivets pass through the round holes and are fixed on the clutch cover. Wire support rings are installed on both sides of the diaphragm spring. These two wire support rings are the fulcrums when the diaphragm spring works. The outer edge of the diaphragm spring is connected to the pressure plate through a release hook.

[0003] A detection device for a clutch diaphragm spring is disclosed in Chinese Patent (Publication No.: CN217716839U), which includes a machine body and a spring to be tested. A circular groove body for placing the spring to be tested is arranged on the bottom wall inside the machine body. A pressing mechanism for pressing the spring to be tested and a detection mechanism for detecting the spring to be tested are arranged inside the machine body. A positioning mechanism is also included. The positioning mechanism includes a central column. The central column is vertically arranged in the circular groove body. A plurality of arc-shaped top pieces are telescopically arranged on the side wall of the central column for the arc-shaped top pieces to contact the spring to be tested and limit the movement track of the spring to be tested. In this clutch diaphragm spring detection device, by arranging a plurality of telescopically arranged arc-shaped top pieces on the central column, the column dimension composed of each arc-shaped top piece that is close to a cylinder can be adjusted arbitrarily, and the middle hole of various models of diaphragm springs can be adapted, achieving the purpose of high applicability.

[0004] For the above-mentioned clutch diaphragm spring detection device, by starting the air cylinder, the dimension of the column composed of the arc-shaped top pieces is adjusted until the arc-shaped top pieces contact the middle hole of the spring to be tested. At this time, the column composed of the arc-shaped top pieces can adapt to different springs to be tested. However, by contacting the middle hole of the spring to be tested with the arc-shaped top pieces, the middle hole is the finger end part of the spring to be tested. Since the finger end part is composed of multiple discrete small structures, the contact is unstable and it is easy to cause deformation of the finger end part. Content of the Utility Model

[0005] The purpose of the utility model is to provide a detection device for a clutch diaphragm spring to solve the above problems existing in the prior art.

[0006] The technical problem to be solved by the utility model is to provide a detection device for a clutch diaphragm spring.

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] A detection device for a clutch diaphragm spring includes a machine body. A shell is arranged at the bottom of the inner cavity of the machine body. Fixing mechanisms are arranged on both sides of the shell. A fixing column is arranged upward in the middle of the shell;

One end of each vertical plate is provided with a motor, and the output shaft of the motor is provided with a first bevel gear. A second bevel gear is engaged with the first bevel gear. A rotating rod is arranged inside the second bevel gear. Worm gears are arranged on both the front and rear sides of the rotating rod. The fixing mechanism further includes two lead screws rotatably arranged between the left and right ends of the opposite sides of the inner cavity of the housing through bearings. A worm wheel engaged with the worm gear is arranged in the middle of the lead screw. Reverse threads are arranged at both ends of the lead screw. Moving blocks penetrating through the through holes at the top of the machine body are threadedly connected to both ends of the lead screw. Connecting blocks are arranged on the opposite sides of the left and right groups of moving blocks. Clamping plates are arranged on the opposite sides of the left and right groups of connecting blocks.

[0010] The beneficial effects of the present utility model are as follows: By inserting the diaphragm spring into the fixing column, the diaphragm spring is located at the top of the housing for preliminary positioning of the diaphragm spring. Start the motor, the motor drives the first bevel gear to rotate, drives the second bevel gear and the rotating rod to rotate together through the first bevel gear, and drives the worm gear to rotate together through the rotating rod. Since reverse threads are arranged at both ends of the lead screw, by rotating the lead screw, the left and right two moving blocks are driven to move relatively simultaneously. The moving blocks drive the clamping plates to move through the connecting blocks. The clamping plates are abutted against the disc part of the diaphragm spring, realizing the clamping and fixing of the diaphragm spring, which can be adjusted and fixed according to diaphragm springs of different sizes. And by clamping and fixing the disc part of the diaphragm spring, it replaces the finger-end contact fixing in the prior art. Since the disc part is an integral ring structure, the clamping is stable and the disc part is not easily deformed, that is, the diaphragm spring is not easily deformed.

[0011] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0012] Further, two sliding rods are arranged on the opposite sides of the two vertical plates. The moving blocks are slidably sleeved on the outer surfaces of the sliding rods.

[0013] Further, the opposite sides of the two worm gears are respectively rotatably connected to the front and rear ends of the opposite sides of the inner cavity of the housing through bearings.

[0014] Further, arc-shaped grooves are formed on the opposite sides of the two clamping plates.

[0015] Further, a cylinder is arranged at the top of the inner cavity of the machine body. The output end of the cylinder is provided with a pressing head, and an annular pressing plate is arranged on the pressing head.

[0016] Further, two telescopic rods are arranged at the top of the inner cavity of the machine body. The bottoms of the telescopic rods are arranged on the top of the annular pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS
