Technical Field

The invention relates to a motor clutch sucker and a manufacturing method thereof, which can effectively improve the adsorption function of a clutch sucker and prolong the service life of the motor clutch sucker, and belongs to the field of clutch sucker manufacturing.

Background

In the structural design of the existing sucker, the sucker is circular, a central hole is formed in the surface of the sucker, and a brake rubber sheet is bonded to the surface of the sucker. The method has the following defects: firstly, when the brake rubber sheet is bonded on the surface of the suction disc, the rubber sheet has large area, large wind resistance and large energy consumption during braking; secondly, because the braking rubber sheet is of a single-layer single-hardness structure, the rubber sheet and a combined surface are easy to slip during braking, so that the braking precision is directly influenced, the phenomena of abrasion and wear deviation are serious, and the service life is short.

Disclosure of Invention

The design purpose is as follows: the defects in the prior art are avoided, and the clutch sucker for the motor and the manufacturing method thereof are designed, so that the adsorption function of the clutch sucker can be improved with glue, and the service life of the clutch sucker for the motor can be prolonged.

The design scheme is as follows: in order to achieve the above design objectives. The invention has the structural design that: 1. the invention is characterized in that the disc surface of the sucking disc is provided with an annular groove, and a composite silica gel ring is arranged in the annular groove. The purpose of this design is: because the hardness that compound silica gel circle its bottom silica gel layer that is located the annular groove is greater than the hardness on surface course silica gel layer in the structure constitution, and the silica gel head (boss) that is located the through-hole of annular groove tank bottom interval distribution is as an organic whole with bottom silica gel layer, just as fixed connection bolt, with bottom silica gel layer and sucking disc annular groove solid as an organic whole, just as the strengthening rib is put into bottom silica gel in situ again, has improved the intensity on bottom silica gel layer effectively. The surface layer silica gel layer compounded on the bottom layer silica gel layer has hardness smaller than that of the bottom layer silica gel layer, so that when the clutch is stressed, the surface layer silica gel layer is subjected to micro-deformation under the bidirectional action of the bottom layer silica gel layer and the clutch surface, the surface layer silica gel layer is firmly combined on the surface of the surface layer, the braking effect on the motor is achieved, the braking error value is very small, the precision is very high, and the automatic control requirement is met. 2. The design that the surface of the sucker between the central hole and the groove is recessed downwards to form a suction cavity is the second technical characteristic of the invention. The purpose of this design is: when the sucking discs are sucked, the sucking discs can press the sucked ambient air into the sucking cavity for diffusion, so that the air is prevented from being pressed to form reverse acting force, and the sucking of the sucking discs is more reliable. 3. The design that the thickness of the surface layer silica gel layer is less than 1mm is the third technical characteristic of the invention. The purpose of this design is: in the experiment of countless times, it is found that when the thickness of surface layer silica gel layer is greater than 1mm, although the actuation braking is good, the actuation precision of sucking disc is influenced by the elasticity of surface layer silica gel layer, its braking precision is unsatisfactory, and when the thickness of surface layer silica gel layer is less than 1mm, not only the actuation braking performance of sucking disc is good, and sucking disc actuation precision is high moreover.

The technical scheme 1: a clutch sucker for a motor is circular, a central hole is formed in the surface of the sucker, an annular groove is formed in the surface of the sucker located on the outer side of the central hole, and a composite silica gel ring is arranged in the annular groove.

The technical scheme 2 is as follows: a method for manufacturing clutch sucker for motor includes such steps as making sucker by punching, turning and grinding, mixing two kinds of silica gel with different hardness to make bottom layer of silica gel, controlling the hardness of hard layer of silica gel to 80-90A, preparing surface layer of silica gel with different hardness to 60-75A, filling the bottom layer of silica gel into sucker to form a layer occupying two thirds of the volume of sucker cavity, and filling the surface layer of silica gel into the surface of bottom layer of sucker.

Compared with the background technology, the invention not only effectively improves the adsorption function of the clutch sucker, but also fundamentally improves the precision and the reliability of the clutch sucker for the motor, and the error of the braking precision is less than 0.01 mm; and secondly, the service life of the sucker is prolonged by nearly 33% under the condition of the same use object test.
