Description

Technical Field

[0001] This utility model belongs to the technical field of wheel hub axle head assembly equipment, and specifically refers to an adjustable locking device for wheel hub axle head bolts. Background Technology

[0002] The wheel hub is one of the key components of a vehicle, and its main functions are to bear the weight and provide precise guidance for the rotation of the wheel hub.

[0003] Currently, hubcaps are commonly used to connect wheel hubs and disc brake discs. Different wheel hubs are fitted with different hubcaps, and the hubcaps use different bolt holes to accommodate disc brake discs of different sizes. Existing disc brake discs are installed in a semi-automatic manner, using a universal screwdriver bit and socket to tighten bolts at various positions. This method results in slow screw installation, and if it is necessary to replace the disc brake disc with a different size, it requires cumbersome adjustments, and the testing process is time-consuming. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable locking device for wheel hub axle bolts, which is adapted to the bolt position adjustment when installing disc brake discs of different sizes, and the locking is more efficient, thus improving assembly efficiency.

[0005] The purpose of this utility model is achieved as follows:

[0006] An adjustable locking device for wheel hub axle head bolts includes a variable diameter base plate, a variable diameter upper guide plate, and several bit spindles for locking the bolts. Both the variable diameter base plate and the upper guide plate have radially evenly distributed sliding grooves, which correspond vertically. A locking limiting plate, coaxially rotating, is provided between the variable diameter base plate and the upper guide plate, and the locking limiting plate has an arc-shaped groove corresponding to the sliding grooves. The bit spindles sequentially pass through the sliding grooves of the upper guide plate, the arc-shaped grooves of the locking limiting plate, and the sliding grooves on the variable diameter base plate. A longitudinally arranged drive motor is mounted on the variable diameter base plate, and a drive wheel is fixed to the output shaft of the drive motor. A driven external tooth adapted to the drive wheel is provided on the side wall of the locking limiting plate. When the drive wheel drives one end of the driven external tooth to the other end, it drives the locking limiting plate to rotate, while the bit spindle slides from one end of the sliding groove to the other.

[0007] The present invention is further configured such that the upper end cover of the variable diameter upper guide plate is provided with a guide plate, and the side wall of the guide plate is provided with the same number of limiting slides as the arc grooves. Each of the bit spindles is fitted with a limiting plate that slides along the limiting slide. When the driving wheel drives the driven external tooth and drives the locking wire limiting plate to rotate, the limiting plate slides along the corresponding limiting slide.

[0008] The present invention is further configured such that the guide plate, the locking wire limiting plate, and the variable diameter upper guide plate are all concentrically arranged.

[0009] The present invention is further configured such that the end of the variable diameter upper guide plate is formed with a side ear, a centering cylinder is provided on one side of the side ear, and a rubber pad for abutting against the side ear is provided on the output shaft of the centering cylinder.

[0010] The present invention is further configured such that a bit sleeve is sleeved on the bottom part of the bit spindle extending out of the variable diameter base plate, a feeding chuck is fixed at the bottom of the bit sleeve, and a bolt tube for feeding bolts is provided on one side of the feeding chuck. A screw for tightening bolts is fixed at the bottom of the bit spindle, and the screw extends out of the feeding chuck.

[0011] The present invention is further configured such that a partition block is provided inside the limiting slide, and the partition block and the inner wall of the limiting slide form a partition hole. The limiting plate is fixed to the shaft wall of the bit spindle by bolts by the first partition plate and the second partition plate, and the end of the second partition plate slides into the partition hole or slides out of the partition hole as the bit spindle moves.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0013] 1. The locking wire device provided by this utility model utilizes the rotation of the drive motor to drive the rotation of the locking wire limiting plate, thereby driving the synchronous expansion or contraction of several batch head spindles, greatly improving assembly efficiency, and also facilitating the adjustment of spacing, thus having a wider range of applications.

[0014] 2. The guide plate further provided in this utility model can allow the limiting plate to slide along the limiting slide opening during the synchronous movement of several batch head spindles, thus playing a good guiding role.

[0015] 3. This utility model has a centering cylinder on one side of the variable diameter upper guide plate, which can ensure that the variable diameter upper guide plate remains fixed when driving the locking wire limiting plate, preventing synchronous rotation and thus ensuring the synchronous movement of the bit spindle.

[0016] 4. This utility model has a bit sleeve at the bottom of the bit spindle, which can not only adapt to the tightening of different bolts, but also has a bolt tube to continuously supply material to the feeding chuck, ensuring the continuous operation of the device. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3 :

[0029] An adjustable locking device for wheel hub axle head bolts includes a variable diameter base plate 1, a variable diameter upper guide plate 2, and a plurality of screwdriver bit spindles 3 for locking the bolts. Both the variable diameter base plate 1 and the variable diameter upper guide plate 2 have radially evenly distributed sliding grooves 10, which correspond vertically. A locking bolt limiting plate 4, which rotates coaxially between the variable diameter base plate 1 and the variable diameter upper guide plate 2, is provided. The locking bolt limiting plate 4 has arc-shaped grooves 40 corresponding to the sliding grooves 10. The plurality of screwdriver bit spindles 3 are arranged according to... The sliding groove 10 of the variable diameter upper guide plate 2, the arc groove 40 of the locking wire limiting plate 4, and the sliding groove 10 on the variable diameter base plate 1 are all passed through. A longitudinally arranged drive motor 5 is provided on the variable diameter base plate 1, and a drive wheel 50 is fixed on the output shaft of the drive motor 5. A driven external tooth 41 adapted to the drive wheel 50 is provided on the side wall of the locking wire limiting plate 4. When the drive wheel 50 drives one end of the driven external tooth 41 to the other end, it drives the locking wire limiting plate 4 to rotate. At the same time, the bit spindle 3 slides from one end of the sliding groove 10 to the other end.

[0030] During the assembly process of bolts, there are usually four or five bolts installed on the disc brake disc, and they are in the same circle. When the locking wire limit plate 4 is processed to the same size, there is no need for the drive wheel to drive it, so that it can perform continuous bolt assembly operations on the disc brake disc of the same size.

[0031] If it is necessary to replace the disc brake disc with a different size for installation, the drive motor will work to make the locking wire limiting plate 4 rotate, thereby driving the rotation of several arc-shaped grooves 40. When rotating, it will push the bit spindle 3, causing several to move synchronously. The movement process is to expand or shrink to adapt to different disc brake disc bolt mounting hole positions.

[0032] In the above structure, the sliding groove 10 is a radial groove with the center of the three plates, while the arc groove 40 is not. It is mainly used to drive the movement of the bit spindle 3. The variable diameter base plate 1 and the variable diameter upper guide plate 2 remain stationary, thereby ensuring accurate synchronization.

[0033] Preferably, the upper end of the variable diameter upper guide plate 2 is covered with a guide plate 6, and the side wall of the guide plate 6 is provided with the same number of limiting slides 60 as the arc grooves 40. Each of the bit spindles 3 is fitted with a limiting plate 30 that slides along the limiting slide 60. When the drive wheel 50 drives the driven external gear 41 and drives the locking wire limiting plate 4 to rotate, the limiting plate 30 slides along the corresponding limiting slide 60.

[0034] In the above structure, the bit spindle 3 is driven by the rotation of the locking wire limiting plate, and the point of action is the side wall of the arc-shaped groove, while the bit spindle 3 itself is relatively long. The guide plate 6 at the upper end can provide a stable effect for the bit spindle during sliding and prevent the bit spindle from deviating.

[0035] Preferably, the guide plate 6, the locking wire limiting plate 4, and the variable diameter upper guide plate 2 are all concentrically arranged. This concentric arrangement ensures that rotating the locking wire limiting plate 4 guarantees accurate movement of each bit spindle in each arc groove, resulting in stronger synchronization.

[0036] Preferably, the end of the variable diameter upper guide plate 2 is formed with a side lug 20, a centering cylinder 21 is provided on one side of the side lug 20, and a rubber pad 22 for abutting against the side lug 20 is provided on the output shaft of the centering cylinder 21.

[0037] In the above structure, in order to keep the variable diameter upper guide plate 2 fixed, the centering cylinder 21 is used to continuously squeeze and push the side ear to keep it fixed and improve stability.

[0038] Preferably, the bit spindle 3 extends out of the bottom portion of the variable diameter base plate 1 and is fitted with a bit sleeve 7. A feeding chuck 70 is fixed to the bottom of the bit sleeve 7, and a bolt tube 71 for feeding bolts is provided on one side of the feeding chuck 70. A screw for tightening bolts is fixed to the bottom of the bit spindle 3, and the screw extends out of the feeding chuck.

[0039] In the above structure, the bit spindle 3 has a bit sleeve at its bottom for tightening bolts. The feed chuck is a two-part structure and is clamped by a spring. The bolt tube 71 continuously feeds the bolts, squeezing the feed chuck to open it, thereby conveying the bolts for installation.

[0040] Preferably, a partition 61 is provided inside the limiting slide 60, and the partition 61 and the inner wall of the limiting slide 60 form a partition hole 62. The limiting plate 30 is fixed to the shaft wall of the bit spindle 3 by bolts by the first partition 300 and the second partition 301, and the end of the second partition 301 slides into or out of the partition hole 62 as the bit spindle 3 moves.

[0041] During the movement of the bit spindle 3, the second partition 301 slides in or out of the partition hole 62 to provide reasonable guidance, ensuring that several bit spindles 3 move synchronously and the guidance is more accurate.

[0042] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
