Description

Technical Field

[0001] The utility model relates to the technical field of gear processing equipment, in particular to a pneumatic clamping device for processing reducer gears. Background Art

[0002] The interior of the reducer is composed of multiple sets of gear structures. The gears are processed before assembly. The gears are fixed by pneumatic clamping tools during processing. The pneumatic clamping tools are mainly composed of two parts: external clamping and internal clamping. Different gear models and processing methods use different pneumatic clamping tools.

[0003] Internal clamping is required to remove burrs from the outer tooth ends of the gear. The gear is clamped in the inner hole of the gear through pneumatic drive. The clamping plate expands outward to fix the gear. After processing, the pneumatic drive can be turned off to remove the gear.

[0004] However, the contact gap between the inner wall of the gear and the outer wall of the clamping plate is small. When processing the gear burrs, foreign matter will be present at the connection between the gear and the clamping plate. When the clamping plate is loose, it will fall into the gap, and the gear will easily become skewed and difficult to remove during unloading. When manually removing it, it needs to be shaken left and right to be removed, which makes unloading inconvenient.

[0005] In order to solve the above problems, the present application proposes a pneumatic clamping device for processing reducer gears. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A pneumatic clamping device for processing reducer gears comprises a body 1, the upper end of the body 1 is fixedly connected to a base 2, the upper end of the base 2 is provided with a pneumatic connecting seat 3, the outer end of the pneumatic connecting seat 3 is sleeved with a gear 4, the outer end of the pneumatic connecting seat 3 is provided with an ejection assembly, the ejection assembly comprises a top ring 6, the lower end of the top ring 6 is fixedly connected to a plurality of ejector rods 7, the ejector rods 7 are sleeved with a first spring 8, the lower end outer wall of the pneumatic connecting seat 3 is fixedly connected to a top seat 5, the ejector rod 7 penetrates the top seat 5, the end of the ejector rod 7 located at the lower end of the top seat 5 is fixedly connected to a fixing ring 10, and both sides of the base 2 are fixedly connected to clamping parts, which are matched with the fixing ring 10.

[0023] Specific working principle and implementation method: the gear 4 is sleeved on the pneumatic clamp, and the gear 4 is pneumatically fixed by the pneumatic connecting seat 3 (it is an existing well-known technology, and the specific structure and principle are not described in detail here). An ejection assembly is provided at the outer end of the pneumatic connecting seat 3. When the gear 4 is pressed downward and fixed, the top ring 6 is pressed downward, and the ejector 7 is driven to move downward during pressing, and the first spring 8 is squeezed by the top ring 6 to shrink. The fixing ring 10 at the lower end of the ejector 7 continues to move downward until it is connected with the clamping piece, and the fixing ring 10 is limited and fixed by the clamping piece to provide stability. Then, after the processing of the gear 4 is completed, the pneumatic connecting seat 3 is closed, and the clamping pieces on both sides are opened. The top ring 6 is ejected upward by the elastic force of the first spring 8, and the ejected top ring 6 steadily pushes the gear 4 out of the pneumatic connecting seat 3; the advantage of such a design is that the gear 4 squeezes the top ring 6 during installation, and after the processing is completed, the gear 4 is ejected to the outer end by the elastic force of the first spring 8, and the ejection force is stable and upward, so that the gear 4 can be removed steadily, which is convenient for the unloading of the gear 4.

[0024] like Figure 4As shown, the clamping member includes a fixed seat 11, in which a clamping block 12 is rotatably connected, and an outer end of the fixed seat 11 is fixedly connected to a baffle 14, and an inner end of the baffle 14 is fixedly connected to a second spring 13, and the other end of the second spring 13 is fixedly connected to the clamping block 12, and a dial plate 15 is fixedly connected to the outer side wall of the upper end of the clamping block 12. When the gear 4 is pressed downward, the top ring 6 and the push rod 7 are driven to move downward, and the push rod 7 moves downward to make the fixed ring 10 contact with the upper end of the clamping block 12, and the clamping block 12 is squeezed outward, and rebounds under the action of the second spring 13 to clamp the clamping block 12 at the upper end of the fixed ring 10. After the processing of the gear 4 is completed, the dial plate 15 is dialed to drive the clamping block 12 to rotate to the outer end, and the top ring 6 can be pushed upward under the action of the first spring 8, and the discharge of the gear 4 can be convenient.

[0025] like Figure 2 As shown, the outer end of the top ring 6 is fixedly connected with a protective cover 9, and the lower end of the protective cover 9 is located on the upper part of the outer wall of the top seat 5. When the gear 4 is processed, cooling water will be sprayed out. The protective cover 9 can reduce the external cooling water spraying into the interior of the ejection assembly, thereby increasing the service life of the first spring 8.

[0026] like Figure 4 As shown, the lower end of the block 12 is fixedly connected with a support rod 16, which is tilted upward and has a rounded end. When the block 12 rotates outward, it drives the support rod 16 to rotate upward. When the support rod 16 rotates upward, it abuts against the lower end of the fixed ring 10. The force of the block 12 rotating outward assists the elastic force of the first spring 8, increases the upward ejection force, and makes it easier to discharge the gear 4.

[0027] like Figure 4 As shown, the paddle 15 is tilted outward, and the edge of the paddle 15 is set at a circular arc angle. The paddle 15 is tilted toward the outer end to facilitate the user to pry it outward with the hand, and the prying position is set at a circular arc angle to facilitate the user to use comfortably.

[0028] like Figure 2 As shown, the protective cover 9 is transparent. The protective cover 9 is transparent to facilitate observation of the internal ejection situation and to facilitate timely maintenance and repair.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
