DETAILED DESCRIPTION

[0024] 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.

[0025] The utility model provides two technical solutions:

[0026] Figure 1-6The first embodiment is shown: a device for matching a rim and a spoke, comprising a base plate 1 and an electric screwdriver 5, a positioning assembly 2 for positioning the rim is provided at the upper end of the base plate 1, an automatic assembly assembly 3 for automatically tightening bolts is provided at the upper end of the base plate 1, and a driving mechanism 4 for driving the automatic assembly assembly 3 to work intermittently is provided at the upper end of the base plate 1;

[0027] The positioning assembly 2 includes an alignment ring 205 automatically set at the upper end of the base plate 1, and an internal pressure inclination angle 206 is provided on the inner surface of the alignment ring 205. A plurality of connecting columns 207 are fixedly provided at the lower end of the alignment ring 205, wherein two connecting columns 207 are fixedly provided with follower blocks 208 at the lower ends. The two follower blocks 208 are symmetrically arranged with the center line of the alignment ring 205 as the axis. The center line of the alignment ring 205 is the straight line between the two farthest points on the outer ring of the alignment ring 205. The lower end of the follower block 208 is provided with a rounded corner, thereby reducing the contact area between the follower block 208 and the unlocking groove 202 to reduce friction.

[0028] In the embodiment of the utility model, an annular groove 201 is provided at the upper end of the base plate 1, an unlocking groove 202 is provided at the lower end of the annular groove 201, two lifting blocks 203 are fixedly provided on the inner surface of the unlocking groove 202, and the two lifting blocks 203 are symmetrically arranged with the center line of the alignment ring 205 as the axis, and a rounded corner is provided at the lower end of the driven block 208, thereby reducing the contact area between the driven block 208 and the lifting block 203 to reduce the friction.

[0029] In the embodiment of the utility model, the lower end of the connecting column 207 slides on the inner surface of the annular groove 201, and the lower end of the driven block 208 slides on the inner surface of the unlocking groove 202. The upper end of the base plate 1 is rotatably provided with a rotating plate 204. When the rim is pressed down by the alignment ring 205, the rim is driven to rotate by the rotating plate 204 to prevent the rim from rotating on its own or the rotation is not synchronized with the alignment ring 205.

[0030] Figure 1-2 4-6 show a second embodiment, which mainly differs from the first embodiment in that the automatic assembly component 3 includes a connecting plate 301 fixedly arranged at the upper end of the base plate 1, a driven column 302 is slidably arranged in the middle of the connecting plate 301, a fixing plate 303 is fixedly arranged on the upper end of the driven column 302, a pressure spring 304 is sleeved on the outer side of the driven column 302, one end of the pressure spring 304 is fixedly connected to one end of the fixing plate 303, and the other end of the pressure spring 304 is fixedly connected to one end of the connecting plate 301, and an electric screwdriver 5 is fixedly connected to the lower end of the driven column 302. The fixed connection of the pressure spring 304 prevents the driven column 302 from excessive rotation, causing the driven column 302 to detach from the eccentric plate 406 in the driving mechanism 4.

[0031] In the embodiment of the utility model, the driving mechanism 4 includes a motor 401 fixedly arranged at the upper end of the base plate 1, an output rod 402 is fixedly arranged at the output end of the motor 401, a turntable 403 is fixedly pressed on the outer surface of the output rod 402, a plurality of active gear blocks 404 are fixedly arranged on the outer surface of the turntable 403, a driven gear ring 405 is fixedly arranged on the outer surface of the alignment ring 205, the active gear block 404 and the driven gear ring 405 are meshedly arranged, the motor 401 is a servo motor, and the rotation speed of the motor 401 is controlled according to the spacing between two adjacent threaded holes on the spoke surface, so as to tighten the threaded holes with different spacings.

[0032] In the embodiment of the utility model, an eccentric plate 406 is fixedly provided at the upper end of the output rod 402, and a driving inclined groove 407 is opened at the upper end of the eccentric plate 406. The inclination angle of the driving inclined groove 407 contacts the inside of the lifting groove 408. The outer surface of the driven column 302 is provided with a lifting groove 408, and the eccentric plate 406 and the active gear block 404 are in the same reverse setting.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] When in use, the operator installs the spoke into the rim, and then places the bolt inside the threaded hole, and then turns on the motor 401 in the driving mechanism 4, and then drives the output rod 402 to rotate, and then the turntable 403 rotates, and then drives the active gear block 404 to rotate, and then drives the driven gear ring 405 to rotate through gear meshing, and then the alignment ring 205 in the positioning assembly 2 rotates, and then the connecting column 207 rotates inside the annular groove 201 to limit the alignment ring 205, so that the alignment ring 205 can only rotate on its own. When the connecting column 207 rotates, the driven block 208 is driven to rotate, and then the driven block 208 rotates inside the unlocking groove 202, and then the two driven blocks 208 contact the two lifting blocks 203 respectively, and then the alignment ring 205 is lifted, and then the rim is placed under the alignment ring 205. The alignment ring 205 rotates further, and then the driven block 208 is separated from the lifting block 203, and then the alignment ring 205 presses down the rim through the internal pressure inclination angle 206, and then the rim is placed directly under the alignment ring 205;

[0035] When the output rod 402 rotates, the electric screwdriver 5 is opened at the same time, thereby driving the eccentric plate 406 to rotate, and then driving the driving inclined slot 407 to rotate, so that the driving inclined slot 407 drives the driven column 302 to rise upward through the lifting slot 408, and then the driven column 302 drives the electric screwdriver 5 to rise, so that the electric screwdriver 5 is separated from the bolt, and the rim rotates, and then the next bolt is placed under the electric screwdriver 5. Through the pressure of the pressure spring 304, the position of the fixing plate 303 is contracted, and then the electric screwdriver 5 is driven through the driven column 302, so that when the rim is stationary, the electric screwdriver 5 is always placed on the bolt surface to automatically tighten the bolt.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
