Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, in particular to a multi-functional fixture tooling for Kaba wheels. Background Art

[0002] With the popularity of vehicles, vehicle parts are increasingly in demand by the public. In the process of wheel production, it is necessary to meet both product quality and production efficiency. For Kaba wheel hubs, they are characterized by large size, many hole positions to be processed, and long processing time.

[0003] The traditional process is that the mounting holes and air holes are completed by different machining centers. The mounting holes on the Kaba wheel hub are evenly distributed on a specified diameter on the plane, while the air holes are evenly distributed on the hub ribs, all on the inclined plane.

[0004] The traditional process is not only time-consuming and laborious, but also the secondary clamping is likely to cause inaccurate center positioning, resulting in bruising of the center hole. In the traditional process, it is not convenient to do anti-slip treatment during clamping, and there is a probability that the Kaba wheel will fall off during processing. In order to complete the machining of bolt holes and air holes at the same time through one clamping on the process, a machining center can complete the processing quickly and achieve high-efficiency processing. Therefore, a multi-functional fixture tooling for Kaba wheels is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a multi-functional fixture tooling for Kaba wheels, aiming to improve the problems of difficult center positioning and inconvenient anti-slip treatment in the existing technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A multi-functional fixture tooling for Kaba wheels, including a positioning disk. The middle part of the top end of the positioning disk is fixedly connected with an electric telescopic rod. The middle upper part of the output end of the electric telescopic rod is fixedly connected with a displacement mechanism. A chuck is fixedly connected to the displacement mechanism. The displacement mechanism is used to push the chuck. The bottoms of the multiple chucks are all fixedly connected with a limiting mechanism, and the limiting mechanism prevents the chuck from shifting up and down. The outer sides of the multiple chucks are all fixedly connected with an anti-slip mechanism, and the anti-slip mechanism is used to prevent the wheel from slipping during processing.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the positioning disk is fixedly connected with a base.

[0010] As a further description of the above technical solution:

[0011] The displacement mechanism includes a positioning ring. The upper middle part of the output end of the electric telescopic rod is fixedly connected to the inner end of the positioning ring. The positioning ring is annularly and evenly distributed with second sleeves rotatably connected thereto. One end of a connecting rod is fixedly connected to the outer side of each second sleeve, and the other end of the connecting rod is fixedly connected to a first sleeve. Grooves are formed at the inner tops of the plurality of chucks, and a connecting shaft is fixedly connected to the middle of the grooves. The connecting shaft is rotatably connected to the inside of the first sleeve.

[0012] As a further description of the above technical solution:

[0013] The limiting mechanism includes T-shaped sliders. The bottom ends of the plurality of chucks are fixedly connected with T-shaped sliders. T-shaped chutes are annularly and evenly formed at the top end of the positioning disc, and the T-shaped sliders are slidably connected to the inside of the T-shaped chutes.

[0014] As a further description of the above technical solution:

[0015] The anti-slip mechanism includes anti-slip sleeves. The anti-slip sleeves are fixedly connected to the outer sides of the plurality of chucks, and anti-slip patterns are formed on the anti-slip sleeves.

[0016] As a further description of the above technical solution:

[0017] The anti-slip mechanism includes anti-slip sleeves. The anti-slip sleeves are fixedly connected to the outer sides of the plurality of chucks, and anti-slip patterns are formed on the anti-slip sleeves.

[0018] As a further description of the above technical solution:

[0019] A plurality of through holes are equidistantly formed in the plurality of chucks.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, since the chucks are arranged on concentric circles, when fixing, the electric telescopic rod is started by the motor. When the electric telescopic rod moves upward, it drives the positioning ring to move upward together. At this time, the second sleeve rotates to drive the connecting rod to rotate. While the connecting rod rotates, since the positioning ring moves upward, at this time the connecting rod pushes the chuck to move outward. Due to the interaction between the bottom T-shaped chute and the T-shaped slider, the chuck clamps the inner side of the wheel, and since the movement frequencies of the three chucks are the same, when positioning, the center of the clamped wheel must coincide with the center of the concentric circles of the chucks, so as to achieve the effect of central positioning, and solve the problem of not being easy to perform central positioning in the prior art.

[0022] 2. In the present utility model, the anti-slip sleeve outside the chuck is made of rubber material. When contacting the inside of the wheel, due to the characteristics of rubber, the wheel is not likely to slip. In addition, the anti-slip lines provided on the anti-slip sleeve further increase the friction and further ensure the clamping effect. Moreover, the displacement mechanism presses against the inner side of the chuck, thereby achieving the effect of not being easily slipped off, solving the problem of inconvenient anti-slip treatment in the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-4, an embodiment provided by the utility model: a multi-functional fixture tool for a Kaba wheel, including a positioning disk 1. In the middle of the top end of the positioning disk 1, an electric telescopic rod 5 is fixedly connected. In the upper middle part of the output end of the electric telescopic rod 5, a displacement mechanism is fixedly connected. The displacement mechanism includes a positioning ring 604. The upper middle part of the output end of the electric telescopic rod 5 is fixedly connected to the inner end of the positioning ring 604. A second collar 605 is rotatably connected to the positioning ring 604 in a circumferential distribution. One end of a connecting rod 6 is fixedly connected to the outer side of each second collar 605. The other end of the connecting rod 6 is fixedly connected to a first collar 601. Grooves 603 are opened at the top inner sides of multiple chucks 3. A connecting shaft 602 is fixedly connected to the middle of the groove 603. The connecting shaft 602 is rotatably connected to the inside of the first collar 601. The displacement mechanism is fixedly connected with the chuck 3. The displacement mechanism is used to push the chuck 3. A limiting mechanism is fixedly connected to the bottom of each of the multiple chucks 3. The limiting mechanism includes a T-shaped slider 302. The bottom ends of multiple chucks 3 are fixedly connected with T-shaped sliders 302. T-shaped chutes 101 are opened in a circumferential distribution on the top end of the positioning disk 1. The inside of the T-shaped chute 101 is slidably connected with the T-shaped slider 302. The limiting mechanism prevents the chuck 3 from shifting up and down.

[0031] Refer to Figures 1-4 , an anti-slip mechanism is fixedly connected to the outer side of each of the multiple chucks 3. The anti-slip mechanism includes an anti-slip sleeve 4. The multiple anti-slip sleeves 4 are fixedly connected to the outer sides of the multiple chucks 3. Anti-slip lines 401 are opened on the anti-slip sleeve 4. The anti-slip mechanism is used to prevent the wheel from slipping during processing. A base 2 is fixedly connected to the bottom end of the positioning disk 1. A motor 7 is fixedly connected inside the base 2. The motor 7 is electrically connected to the electric telescopic rod 5. Through holes 301 are opened at equal intervals on the multiple chucks 3. The anti-slip sleeve 4 is made of rubber material.

[0032] Working principle: During clamping, since the multiple chucks 3 are arranged on concentric circles, the electric telescopic rod 5 is started by the motor 7. When the electric telescopic rod 5 moves upward, it drives the positioning ring 604 to move upward together. At this time, the second collar 605 rotates to drive the connecting rod 6 to rotate. While the connecting rod 6 rotates, since the positioning ring 604 moves upward but the length of the connecting pipe remains unchanged, the connecting rod 6 pushes the chuck 3 to move outward at this time. Due to the interaction between the bottom T-shaped chute 101 and the T-shaped slider 302, the chuck 3 clamps the inner side of the wheel. And because the movement frequencies of the three chucks 3 are the same, when positioning, the center of the clamped wheel must coincide with the center of the concentric circle of the chuck 3. The anti-slip sleeve 4 on the outer side of the chuck 3 is made of rubber material. When clamping the wheel, due to the characteristics of rubber, the wheel is not easy to slide. In addition, the anti-slip lines 401 opened on the anti-slip sleeve 4 further increase the friction and further ensure the clamping effect. And when reaching the position, the positioning ring 604 is fixed on the output end of the electric telescopic rod 5, and the connecting rod 6 abuts against the inner side of the chuck 3.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
