Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically a fixing device for processing wheel hub caps. Background Technology

[0002] Wheel covers not only reduce turbulence and high-speed wind noise at specific frequencies, but also enhance the aesthetics of the vehicle without negatively impacting heat dissipation. Wheel covers are typically installed on the side of the wheel hub using clips.

[0003] For example, patent CN210436905U discloses a wheel assembly and a vehicle. The wheel assembly includes: a wheel comprising a rim, a spoke located at the center of the rim, and spokes connecting the rim and the spoke; the rim, the spoke, and the spokes are all made of aluminum alloy; mounting holes are provided on the spokes; and a hubcap having positioning protrusions and positioning buckles, the positioning protrusions engaging with the mounting holes, and the positioning buckles engaging with the spokes. The vehicle includes the wheel assembly.

[0004] In the aforementioned patent, the wheel cover is installed on the side of the wheel using positioning clips; however, during the manufacturing process, the wheel cover body is generally made of alloy or plastic. Regardless of the material, it's highly unlikely that the clips are directly machined onto the wheel cover body using stamping or injection molding. Instead, the clips are typically installed separately on the wheel cover body after its production is complete, using adhesive or welding methods. Furthermore, the wheel cover body needs to be secured during clip installation.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a fixing device for processing wheel hub caps, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The positioning device includes a fixed positioning column and a movable positioning column; two fixed positioning columns are provided and fixedly installed in the middle of the fixed platform, and the movable positioning column is driven to rise and fall by a positioning electric cylinder; the positioning electric cylinder is vertically fixedly installed on the front side of the central support, and a positioning column support is fixedly installed on the output shaft of the positioning electric cylinder, and movable positioning columns are vertically fixedly installed on the left and right ends of the rear side of the positioning column support.

[0010] A pad block electric cylinder is vertically fixedly installed on the rear side of the central support. A pad block bracket is fixedly installed on the output shaft of the pad block electric cylinder. A movable pad block is fixedly installed at the front center of the pad block bracket.

[0011] Furthermore, the central auxiliary clamp includes a first electric cylinder bracket, on the side of which a first electric cylinder is vertically fixedly mounted via a first electric cylinder mounting plate; the output shaft of the first electric cylinder is rotatably connected to the tail of the first pressure arm via a pin; a first transition connecting arm is rotatably connected to the top of the first electric cylinder bracket via a pin, and the top of the first transition connecting arm is rotatably connected to the rear center of the first pressure arm via a pin; a first pressing head is fixedly mounted at the head end of the first pressure arm.

[0012] Furthermore, a V-shaped clearance groove is provided in the middle of the rear side of the positioning column bracket, and the front end of the pad bracket is located in the clearance groove, so that the movable pad at the front end of the pad bracket can be located in the center of the entire fixed platform, thereby enabling the movable pad to support the exact center of the entire hub cover.

[0013] Furthermore, the edge auxiliary clamp includes a second electric cylinder bracket, on the side of which a second electric cylinder is vertically fixedly mounted via a second electric cylinder mounting plate; the output shaft of the second electric cylinder is rotatably connected to the tail of the second pressure arm via a pin; a second transition connecting arm is rotatably connected to the top of the second electric cylinder bracket via a pin, and the top of the second transition connecting arm is rotatably connected to the rear center of the second pressure arm via a pin; a second clamping frame is fixedly mounted at the head end of the second pressure arm, and three second clamping heads are vertically mounted on the second clamping frame.

[0016] The positioning is precise and reliable. Through the coordinated action of the fixed positioning post and the movable positioning post, they are inserted into the clearance hole of the wheel hub cover, which effectively limits the horizontal displacement and ensures that the wheel hub cover does not shift during the welding process.

[0017] Multi-point clamping ensures stability. The central auxiliary clamp is driven by an electric cylinder to press down on the center of the top of the wheel hub cover, while the edge auxiliary clamps use multiple clamping heads to simultaneously fix the wing plate, achieving comprehensive vertical clamping and improving overall stability.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] like Figure 7 As shown, the wheel hub cap 9 processed by this solution is star-shaped, including a central disc 901 and several wing plates 902 extending outward from the edge of the disc 901. The disc 901 also has five clearance holes 903. The clearance holes 903 exist mainly because during use (i.e., when the wheel hub cap is installed on the wheel hub of a car), the nuts on the wheel hub need to be tightened through the clearance holes 903. During processing, this solution cleverly utilizes the clearance holes 903 as the positioning for processing the wheel hub cap.

[0027] Please see Figure 1-6A fixing device for machining wheel hub caps includes a fixing platform 1; the fixing platform 1 is generally disc-shaped, and the bottom of the fixing platform 1 is fixedly installed on the top of the workbench 102 by several columns 101.

[0028] The fixed platform 1 is surrounded by a circular array of edge auxiliary clamps 2, and a central auxiliary clamp 3 is provided on the rear side of the fixed platform 1; a positioning device 4 is provided at the center of the fixed platform 1.

[0029] The positioning device 4 includes a fixed positioning column 401 and a movable positioning column 402; the fixed positioning column 401 is provided with two columns and is fixedly installed in the middle of the fixed platform 1, and the movable positioning column 402 is driven to rise and fall by the positioning electric cylinder 403.

[0030] The positioning electric cylinder 403 is vertically fixedly installed on the front side of the central support 405. A positioning column support 404 is fixedly installed on the output shaft of the positioning electric cylinder 403. Movable positioning columns 402 are vertically fixedly installed on the left and right ends of the rear side of the positioning column support 404.

[0031] When using this solution, the hubcap 9 is placed on the fixed platform 1, and two fixed positioning pins 401 are inserted into two of the clearance holes 903 on the hubcap 9. Then, the positioning electric cylinder 403 extends and the movable positioning pin 402 extends and inserts into the other two clearance holes 903; thereby achieving the positioning of the hubcap 9 and preventing the hubcap 9 from displacing in the horizontal direction.

[0032] The central auxiliary clamp 3 includes a first electric cylinder bracket 301, on the side of which a first electric cylinder 303 is vertically fixedly mounted via a first electric cylinder mounting plate 302; the output shaft of the first electric cylinder 303 is rotatably connected to the tail of a first pressure arm 305 via a pin; a first transition connecting arm 304 is rotatably connected to the top of the first electric cylinder bracket 301 via a pin, and the top of the first transition connecting arm 304 is rotatably connected to the rear-middle position of the first pressure arm 305 via a pin; a first pressing head 306 is fixedly mounted at the head end of the first pressure arm 305.

[0033] Meanwhile, in this solution, a pad block electric cylinder 307 is vertically fixedly installed on the rear side of the central support 405, a pad block bracket 308 is fixedly installed on the output shaft of the pad block electric cylinder 307, and a movable pad block 309 is fixedly installed at the front middle of the pad block bracket 308.

[0034] It is worth noting that a V-shaped clearance groove 310 is provided in the middle of the rear side of the positioning column bracket 404, and the front end of the pad bracket 308 is located in the clearance groove 310, so that the movable pad 309 at the front end of the pad bracket 308 can be located in the center of the entire fixed platform 1, thereby enabling the movable pad 309 to support the center of the entire hub cover.

[0035] When the hub cover 9 is placed on the fixed platform 1, the movable pad 309 is located at the bottom center of the hub cover 9. When the output shaft of the first electric cylinder 303 extends, it drives the tail of the first pressure arm 305 to rise, while the head of the first pressure arm 305 descends to press the top of the hub cover 9.

[0036] The edge auxiliary clamp 2 includes a second electric cylinder bracket 201, on the side of which a second electric cylinder 203 is vertically fixedly mounted via a second electric cylinder mounting plate 202; the output shaft of the second electric cylinder 203 is rotatably connected to the tail of the second pressure arm 205 via a pin; a second transition connecting arm 204 is rotatably connected to the top of the second electric cylinder bracket 201 via a pin, and the top of the second transition connecting arm 204 is rotatably connected to the rear-middle position of the second pressure arm 205 via a pin; a second clamping frame 206 is fixedly mounted at the head end of the second pressure arm 205, and three second clamping heads 207 are vertically mounted on the second clamping frame 206;

[0037] Meanwhile, in this solution, the top of the fixed platform 1 is provided with a number of fixed pads 208 that are adapted to the second pressing head 207;

[0038] The wing plate 902 of the hub cover 9 is placed on the corresponding fixed pad 208; when the output shaft of the second electric cylinder 203 extends, it drives the first end of the second pressure arm 205 to descend, and one of the second pressure heads 207 on the second pressure frame 206 presses on the wing plate 902.

[0039] In this solution, the three second pressing heads 207 at different positions correspond to different models of wheel hub caps 9. In this solution, one model of wheel hub cap 9 is shown.

[0040] When using this utility model, the hub cover 9 is placed on the fixed platform 1, and two fixed positioning pins 401 are inserted into two of the clearance holes 903 on the hub cover 9. Then, the positioning electric cylinder 403 extends out and the movable positioning pin 402 extends out and is inserted into the other two clearance holes 903.

[0041] The movable pad 309 is located at the bottom center of the hub cover 9. When the output shaft of the first electric cylinder 303 extends, the head end of the first pressure arm 305 descends and presses down on the top center of the hub cover 9.

[0042] When the output shaft of the second electric cylinder 203 extends, it drives the first end of the second pressure arm 205 to descend, and one of the second pressure heads 207 on the second pressure frame 206 presses against the wing plate 902.

[0043] Subsequently, the worker can carry out the welding operation. After the welding is completed, the positioning electric cylinder 403 retracts the movable positioning post 402 and pulls it away from below the relief hole 903. The pad electric cylinder 307 extends the movable pad 309 and rises, lifting the entire hub cover 9 upwards so that it is detached from the fixed positioning post 401, making it convenient for the worker to remove.
