Disc type CG section grease injection and deflation clamp

Abstract

The utility model discloses a grease injection and deflation clamp for a disc type CG joint. The grease injection and deflation clamp is characterized by comprising a base, a fixed plate, a sliding plate and a limiting shifting fork, the lower end of the fixed plate is fixed on the base, and the sliding plate is slidably fixed on the fixed plate; the limiting shifting fork is U-shaped, the lower end of a transverse arm of the limiting shifting fork is detachably fixed to the upper end of the sliding plate, and the distance between two vertical arms of the limiting shifting fork is larger than the diameter of a shaft rod at the lower end of the inner end rubber sleeve and smaller than the diameter of a small end opening of the inner end rubber sleeve. The two vertical arms respectively protrude upwards to form a step I and a step II, and the step II is higher than the step I; when the height difference of the step I and the step II meets the requirement for grease injection, the step I and the step II abut against the small end opening of the inner end rubber sleeve, the step II ejects the inner end rubber sleeve out of the protrusion at the end of the shaft rod, and an air bleeding channel is formed at the position. By using the deflation clamp, deflation can be carried out without manual operation, so that the production efficiency is improved, and the risk that an awl punctures or pierces through a rubber sleeve at the inner end is avoided.

Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing and relates to a venting clamp for a disc-type CG section grease injection capping device. Background Technology

[0002] The vehicle half-shaft includes a shaft 13, an outer end section 15 and an outer end sleeve 14 fixed to one end of the shaft 13, an inner end section 9 and an inner end sleeve 10 fixed to the other end of the shaft 13, 11 is a large clamp, and 12 is a small clamp, such as... Figure 1 As shown. The disc-type CG section grease injection and capping equipment is used for grease injection and capping of disc-type CG sections. During grease injection, air must be released at the inner end of the workpiece to prevent gas pressure from hindering grease injection. Existing disc-type CG section grease injection and capping equipment uses... Figure 2 When injecting grease, the cone 1 is inserted into the venting channel from the small clamp end of the inner end sleeve of the inner end section to release air. This venting structure requires the operator to manually insert the cone, which not only affects the overall shaft production progress, but also poses a risk of the cone puncturing or penetrating the inner end sleeve. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems in the prior art and provide a disc-type CG section grease injection and degassing fixture. Using this degassing fixture, degassing can be performed without manual operation, which improves production efficiency and avoids the risk of being punctured or penetrating the inner end rubber sleeve by an awl.

[0004] To achieve the above objectives, the technical solution of this utility model is: a disc-type CG section grease injection and venting clamp, which includes a base, a fixed plate, a sliding plate, and a limiting fork; the lower end of the fixed plate is fixed on the base, and the sliding plate is slidably fixed on the fixed plate; the limiting fork is U-shaped, and the lower end of its horizontal arm is detachably fixed on the upper end of the sliding plate, the distance between its two vertical arms is greater than the diameter of the shaft at the lower end of the inner end rubber sleeve, and less than the diameter of the small port of the inner end rubber sleeve; and the two vertical arms respectively protrude upwards with steps I and II, with step II being higher than step I; the height difference between steps I and II satisfies that when grease is injected, steps I and II press against the small port of the inner end rubber sleeve, and step II pushes the inner end rubber sleeve out of the protrusion at that end of the shaft, so that a venting channel is formed at that point.

[0005] More preferably, the fixed plate has a sliding groove for the sliding plate, and the fixed plate and the sliding plate each have a plurality of corresponding fixing holes; the sliding plate is placed in the sliding groove of the fixed plate and fixed together by a pin inserted into the corresponding fixing holes of the two.

[0006] More preferably, the base has a clearance groove for fixing the outer end section and the outer end rubber sleeve.

[0007] In use, adjust the fixing plate and sliding plate to fit the length of the half-shaft. Fix the base of the venting clamp to the fixing base of the outer end section fixing fixture of the grease injection mechanism of the grease injection capping equipment. Place the inner end section and inner end rubber sleeve on the limiting fork. The shaft is located in the U-shaped opening of the limiting fork. The grease injection head of the grease injection mechanism moves down and presses against the inner end section. The servo motor drives the fixing base of the outer end section fixing fixture to move up, thereby driving the venting clamp of this utility model to rise. The limiting fork abuts against the small port of the inner end rubber sleeve. Step II pushes the inner end rubber sleeve out of the protrusion at this end of the shaft, forming a venting channel. Compared with the prior art, this utility model can vent without manual operation, improving production efficiency and avoiding the risk of being punctured or penetrated by an awl. Furthermore, the venting clamp height is adjustable to accommodate grease injection of half-shafts of various lengths. It also features a limit fork that can be replaced according to the size of the half-shaft to accommodate various shaft diameters and the small port size of the inner end rubber sleeve. It is easy to use and has a wide range of applications. Attached Figure Description

[0010] Figure 3 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0011] The present invention will be further described below with reference to specific embodiments.

[0012] like Figure 3 As shown, this embodiment includes a base 8, a fixed plate 7, a sliding plate 5, and a limiting fork 2. The lower end of the fixed plate 7 is fixed to the base 8, and the sliding plate 5 is slidably fixed to the fixed plate 7. The limiting fork 2 is U-shaped, with its lower end of the horizontal arm detachably fixed to the upper end of the sliding plate 5. The distance between its two vertical arms is greater than the diameter of the shaft at the lower end of the inner end sleeve, but less than the diameter of the small port of the inner end sleeve. The two vertical arms respectively have upward protrusions of steps I3 and II4, with step II4 being higher than step I3. The height difference between steps I3 and II4 is such that when grease is injected, steps I3 and II4 press against the small port of the inner end sleeve, and step II4 pushes the inner end sleeve out of the protrusion at that end of the shaft, thus forming a venting channel. Preferably, the fixed plate 7 has a sliding groove for the sliding plate 5, and the fixed plate 7 and the sliding plate 5 each have multiple corresponding fixing holes; the sliding plate 5 is placed in the sliding groove of the fixed plate 7 and fixed together by pins inserted into the corresponding fixing holes of the two. Preferably, the base 8 has a clearance groove 16 for fixing the outer end section and the outer end rubber sleeve.

[0013] The above-described embodiments are merely preferred and exemplary, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
