Description

Technical Field

[0001] This utility model relates to the field of spindle processing technology, specifically a tire locking spindle for a tire balancing machine. Background Technology

[0002] The dynamic balance parameters of wheel hubs are crucial to vehicle operation. Unbalanced wheel hubs, when rotating at high speeds, can cause vehicle vibrations, affecting ride comfort, shortening tire life, and potentially even leading to traffic accidents. Therefore, dynamic balancing testing of wheel hubs is an essential step in both wheel hub manufacturing and the automotive repair industry. This requires reliable wheel hub fixing technology using a balancing machine spindle to ensure the accuracy of the test results.

[0003] Existing installation methods mostly involve mounting a flange at the end of the balancing machine's spindle, with corresponding mounting holes on the wheel hub. During installation, the mounting holes on the wheel hub are aligned with the holes on the flange, and then the wheel hub is secured to the flange with bolts. This method is similar to the way wheels are mounted on vehicles and is used in some large tire balancing machines or applications requiring high fixation. However, it suffers from relatively complex installation and disassembly processes, requiring tools to tighten or loosen bolts, which is time-consuming. Furthermore, the mounting holes on the flange and wheel hub need high machining precision to ensure a good fit; otherwise, the fixation effect and centering accuracy will be affected. Additionally, over long-term use, wear on the center hole of the wheel hub can lead to stability issues. Therefore, there is an urgent need to improve the tire balancing machine by using a tire-locking spindle to solve these problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This tire balancing machine uses a tire locking spindle. Through the design of the locking mechanism, the wheel hub is fixed by components such as cylinders, locking shafts, large cups, and balance wheels. Compared with the traditional method of fixing with bolts, it is more convenient and labor-saving.

[0014] 2. This tire balancing machine uses a tire-locking spindle. Through the design of the drive mechanism and the detachable cone design, different forward and reverse mounting methods of the cone can be selected according to the center hole design of different wheel rims, making it more stable. During the operation of the car tire balancing machine, regardless of the size of the wheel rim, as long as its center hole has a standard conical design, the cone can ensure that the wheel rim is accurately positioned on the center line of the spindle. This centering function ensures the balance of the tire. At the same time, some high-performance vehicles, racing cars, or specially modified vehicles have special wheel rim designs, such as wheel rims with reverse conical designs, and the center positioning hole of the wheel rim may wear after long-term use. In these cases, the reverse cone design is more suitable, and the detachable design is more adaptable. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Based on existing technology, most systems employ a flange mounted at the end of the spindle, secured to the hub with bolts. This method is relatively complex to install and remove, requiring tools to tighten or loosen the bolts, which is time-consuming. Furthermore, the mounting holes on the flange and hub need high machining precision to ensure a good fit; otherwise, the fixing effect and centering accuracy will be affected. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a tire locking spindle for a tire balancing machine, including a tire 1, a hub 2 fixedly installed in the tire 1, a locking device 3 movably engaged on the right side of the hub 2, a cylinder mounting bracket 4 fixedly installed on the left side of the hub 2, and a cylinder 5 fixedly installed on the cylinder mounting bracket 4; the tire locking spindle for the tire balancing machine includes a locking mechanism and a driving mechanism, the locking mechanism includes the hub 2, a mounting groove 210 on the right side of the center position of the hub 2, a mounting groove 211 on the left side, a cone 207 movably installed in the mounting groove 210, the cone 207 movably installed in the balancing wheel 203, and a large bowl 208 on the left side of the hub 2.

[0025] A cone baffle 205 is provided on the right side of the cone 207. The cone 207 contacts the cone baffle 205. A spring 204 is fixedly installed between the cone baffle 205 and the balance wheel 203. A slot is provided near the left end of the balance wheel 203. A retaining spring 206 is movably installed in the slot.

[0026] The cone 207 fits into the mounting groove 210, the large bowl 208 and the balance wheel 203 clamp the hub 2, and the locking shaft 209 is movably installed in the middle position of the large bowl 208 through the snap-fit ​​mechanism.

[0027] The balance wheel 203 has a main shaft sleeve 202 on the right side, a first shaft sleeve 201 is movably installed on the main shaft sleeve 202, a connecting rod 8 is fixedly installed on the first shaft sleeve 201, and mounting shims 7 are fixedly installed on both sides of the first shaft sleeve 201. A friction wheel 6 is movably installed at the rightmost end of the main shaft sleeve 202.

[0028] Through the design of the locking mechanism, the hub 2 is placed on the main shaft sleeve 202, so that the cone 207 is aligned with the mounting groove 210 at the center of the hub 2. Under the action of the spring 204, the cone 207 is pressed against the inner wall of the mounting groove 210. At the same time, the locking shaft 209 is placed on the left side of the hub 2 with the large bowl 208, so that it passes through the central shaft inside the main shaft sleeve 202 and is locked by the claw mechanism designed inside the locking shaft 209. At the same time, the balance wheel 203 on the right side clamps the hub.

[0029] Example 2:

[0030] Based on Example 1, the specific implementation method for clamping and removing the hub on the main shaft is described below. Please refer to [link / reference needed]. Figures 1-5 This utility model provides a technical solution: a tire locking main shaft for a tire balancing machine, the drive mechanism includes a cylinder 5, a push rod 301 is movably installed in the middle position of the cylinder 5, a connecting shaft 302 is provided on the left side of the push rod 301, the connecting shaft 302 is movably installed in the main shaft 303, the main shaft 303 is fixedly connected to the inner wall of the main shaft sleeve 202 through a bearing 304, and a spring 305 is fixedly installed in the main shaft sleeve 202.

[0031] The top of the connecting shaft 302 is provided with a mounting hole, in which a screw 306 is movably installed. A retaining shaft 307 is movably installed on the left side of the screw 306. An annular washer 316 is installed on the stud part of the screw 306. The retaining shaft 307 is movably installed in the retaining shaft sleeve 308. The retaining shaft sleeve 308 is movably installed in the locking shaft 209. The locking shaft 209 is provided with multiple sets of retaining grooves 309.

[0032] The left end of the retaining shaft 307 is provided with a recycling groove 315. The retaining groove 315 is fixedly installed with a claw shaft 311 and a torsion spring shaft 313. The claw shaft 311 is movably installed with a claw 310. The torsion spring 312 is movably installed on the torsion spring shaft 313. The two torsion spring legs of the torsion spring 312 are in contact with the claw 310. The retaining shaft sleeve 308 is provided with a sliding groove 314. The claw 310 can be completely retracted into the recycling groove 315 without interfering with the movement of the retaining shaft 307 in the retaining shaft sleeve 308.

[0033] The cone is reversed, and the cylinder 5 is activated so that the push rod 301 abuts against the connecting shaft 302. A screw 306 is threaded onto the end of the connecting shaft 302. A retaining groove is provided on the outer surface of the connecting shaft 302, and the retaining shaft 307 is connected to the connecting shaft 302 by the screw. When not clamping, the pawl 310 is fully retracted into the recovery groove 315. When clamping is required, the connecting shaft 302 moves backward under the action of the second spring 305, which in turn moves the retaining shaft 307 backward, causing the pawl 310 to move to the position of the slide groove 314. At this time, the pawl 310 pops out under the action of the torsion spring 312, locking the locking shaft 20. The slot 309 designed inside the 9 completes the clamping. The specific implementation methods for the forward and reverse installation of the cone are basically the same. However, when it is necessary to install the cone 207 in the forward position, simply align the larger side of the cone with the mounting slot 211 designed on the wheel hub 2. When it is necessary to release the wheel hub, the starting cylinder 5 pushes the push rod 301 to move it forward, which in turn drives the clamping shaft 307 to move forward. Due to the sloping design of the front end of the pawl 310, the pawl 310 is disengaged from the position of the slide groove 314 and is completely stored in the recovery groove 315 under the action of the clamping shaft sleeve 308. Remove the large bowl 208 and the locking shaft 209, and then the wheel hub can be removed.
