A torsion spring disc torsion testing device

Abstract

The utility model discloses a torsion spring disc torsion testing device belongs to mechanical manufacturing and detection technical field, and this testing device mainly it includes rack, gear, torsion spring disc, torsion spring disc core shaft and locating bearing. The front and back reciprocating movement of rack is driven through the telescopic of air cylinder and engages the rotation of gear, thereby the torsion of the torsion spring disc locked with gear is driven, because the inner ring of torsion spring disc is fixed and cannot twist, thereby realizes the reciprocating torsion of rubber on the middle ring of torsion spring disc, and the locating bearing plays the limiting and positioning effect to rack. The present application avoids the influence of the test result of the conventional tool because of gear bounce, and the real working condition is simulated to the maximum extent.

Description

Technical Field

[0001] This utility model relates to a torsion test device for a torsion spring disc, belonging to the field of mechanical manufacturing and testing technology, specifically in the field of torsion spring disc durability testing technology, which can achieve efficient and accurate testing of the torsion life of a torsion spring disc. Background Technology

[0002] Large photographic tripods commonly use ball heads, which contain a device called a torsion spring plate. This plate provides damping when adjusting the angle of the photographic equipment, ensuring it won't be damaged by sudden drops without damping, while also maintaining ease of use. Currently, most torsion spring plates on the market use metal torsion springs. The disadvantages are that angle adjustments are somewhat stiff and noisy. After a period of use, the metal may yield and fail to support the equipment, causing it to drop and break. Given these application backgrounds, rubber torsion spring plates have emerged in recent years.

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a damping device that makes the angle of photographic equipment change more smoothly, feels more comfortable, has a longer service life, and can prevent photographic equipment from being damaged by bumping. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a torsion spring disc torsion testing device, which includes a rack, a gear, a torsion spring disc, a torsion spring disc spindle, and a positioning bearing. One end of the rack is connected to a cylinder, which drives it to move linearly. The torsion spring disc is locked to the gear, and the inner ring of the torsion spring disc is fixed to the base plate through the torsion spring disc spindle component. The positioning bearing is fixed to the positioning bearing base by a bearing rod. The torsion of the torsion spring disc is achieved by the extension and retraction of the cylinder driving the rack to move back and forth, meshing with the gear, thereby driving the torsion of the torsion spring disc locked to the gear. Since the inner ring of the torsion spring disc is fixed and cannot be twisted, the rubber on the middle ring of the torsion spring disc reciprocates.

[0005] The advantages and beneficial effects of this invention are as follows: The equipment is simple, easy to operate, and low in cost.

[0006] It is beneficial for accurately testing the lifespan of rubber torsion spring discs, avoiding the impact of gear runout on test results caused by conventional tooling, and simulating real working conditions to the greatest extent. Attached Figure Description

Detailed Implementation

[0010] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention. Example

[0011] like Figures 1 to 2 As shown, it includes a rack (5), a gear (4), a torsion spring disc (2), a torsion spring disc spindle (3), and a positioning bearing (6); one end of the rack (5) is connected to a cylinder (15), which drives it to move linearly; the gear (4) is fixed to the inner ring of the gear bearing (11) by a gear washer (13) at the bottom and a screw; the torsion spring disc (2) is fixed to the torsion spring disc mounting base (1) by its outer ring, and the torsion spring disc mounting base (1) is then locked to the gear (4) by screws; the torsion spring disc spindle (3) is fixed to the inner ring of the torsion spring disc (2); the positioning bearing (6) is fixed to the positioning bearing base (8) by a bearing rod (7); Furthermore, the gear bearing (11) is fixed by a bearing outer ring washer (12) at the bottom and a bearing seat (10) at the top; the bearing seat (10) is fixed to the base plate (9) by screws; the bottom of the torsion spring disc spindle (3) is fixed to the base plate (9) by screws; the positioning bearing base (8) is fixed to the base plate (9) by screws; and the cylinder (15) is locked to the base plate (9) by the cylinder base (14).

[0012] Furthermore, the torsion of the torsion spring disc (2) is achieved by the extension and retraction of the cylinder (15) driving the rack (5) to move back and forth and mesh with the gear (4), thereby driving the torsion spring disc (2) locked with the gear (4) to rotate. Since the inner ring of the torsion spring disc (2) is fixed and cannot be rotated, the rubber on the middle ring of the torsion spring disc (2) is reciprocated and rotated.
