Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production, in particular to an automobile parts clamping tool and an automobile wheel hub clamping method. Background Art

[0002] Auto parts are the units that constitute the overall auto parts processing and are products used for auto parts processing. Various types of tooling products are needed in the production process of auto parts, mainly clamping tooling used in the painting production process of auto parts. When painting auto parts, the position of auto parts needs to be clamped and positioned by clamping tooling for painting parts. When the position of the painted parts is fixed, the clamping tooling of auto parts also needs to have a rotation function so that the painted parts can be painted in all directions.

[0003] The invention with publication number CN114178084B proposes a clamp and method for painting metal processing parts. The clamp slides on the surface of the threaded support rod through a slide cylinder. When the slide cylinder slides up and down, it will pull the bottom end of the traction cylinder so that the three clamps are pressed against the inner edge of the accessory from three directions respectively, fixing the position of the accessory, effectively avoiding the deviation of the accessory caused by two-point clamping. The setting of the spring makes the outward tension value of the clamp adjustable, so that the device can select the appropriate force according to the different strengths of the accessories, avoiding excessive tension and damage to the accessories. However, when clamping automotive parts, the clamp is not convenient to achieve limited clamping in the circumferential and top directions of the parts with only one driving force. As a result, a driving force still needs to be set during use to clamp the top of the part to adapt to the height of the part. Setting up a driving unit again consumes too much cost. Therefore, this scheme specially proposes an automotive part clamping tool and a clamping method for an automotive wheel hub to solve the above problems. Summary of the Invention

[0052] A method for clamping an automobile wheel hub, comprising any of the above-described automobile component clamping fixtures, the method comprising the following steps:

[0053] S1. Place the automobile wheel hub on top of the support plate, and align two opposite sides of the automobile wheel hub in the height direction with two third clamping frames;

[0054] S2. Starting the first motor, the first, second, and third clamping members move synchronously toward the vehicle wheel hub. The first and second clamping members initially abut against the circumference of the vehicle wheel hub. The first motor continues to rotate until the two third clamping members abut against two opposite side surfaces in the height direction. The vehicle wheel hub is limited by the first, second, and third clamping members to complete the clamping process of the vehicle wheel hub.

[0055] S3. When the clamped automobile wheel hub needs to be pulled to move, the transmission gear is rotated. The transmission gear drives the traction chain to rotate along the two transmission gears. The traction chain carries the second mounting seat to move through the connecting component to complete the movement of the automobile wheel hub;

[0056] S4. When the clamped automobile wheel hub needs to be rotated, the second motor is started, and the second motor drives the first mounting seat to rotate along the second sliding frame. By rotating the first mounting seat, the automobile wheel hub is rotated under the limit of the first clamping member, the second clamping member and the third clamping member, thereby completing the rotation processing of the automobile wheel hub.

[0057] The automobile parts clamping fixture and automobile wheel hub clamping method of the present invention have the following beneficial effects compared with the prior art:

[0058] (1) By setting a pushing assembly, when in use, the component body is placed on the top of the support plate for clamping. When the peripheral side and the top of the component body need to be clamped synchronously, the driving mechanism is used to adjust the sliding member to slide in the direction close to the first clamping member and the second clamping member. At this time, the sliding member drives the pushing member to move through the first spring, and the pushing member synchronously pushes the first clamping member and the second clamping member to slide in the direction close to the component body. When one of the first clamping member and the second clamping member contacts the component body, the sliding member continues to slide. At this time, the hinged rod rotates relative to the sliding member and the pushing member. The first clamping member or the second clamping member is pushed by the hinged rod to continue to move in the direction close to the component body until the first clamping member and the second clamping member both conflict with the component body. During this period, the first clamping member can clamp the component body from the side of the component body away from the support plate, and the second clamping member can clamp the component body from the peripheral side of the component body. By limiting the top and peripheral side of the component body, the limited clamping process of the component body is completed. During the clamping period, only one driving force needs to be set to drive the sliding member to slide in the direction close to the first clamping member and the second clamping member, which is convenient to use.

[0059] (2) The first connecting frame and the second connecting frame are connected by a telescopic rod. When the toothed column is driven to rotate by the first motor, the first clamping member, the second clamping member and the third clamping member can be synchronously driven to slide in the direction close to the component body under the action of the first toothed groove and the second toothed groove. In a specific implementation, the two third clamping members are positioned on the narrower sides of the component body. When the first clamping member and the second clamping member are in conflict with the component body, the pushing member cannot move, the toothed column continues to rotate, and the second spring is stretched until the two third clamping members are in conflict with the component body. During this period, the two second clamping members and the two third clamping members can conflict with each other on the circumference of the component body from four sides of the component body, thereby increasing the clamping stability of the component body. By setting the second spring, the clamping tool can adapt to clamping component bodies of different sizes, which is convenient to use.

[0060] (3) By setting up a chain traction mechanism, when in use, the second mounting seat is connected to the traction chain through a connecting component, and the transmission gear is adjusted to rotate so that the traction chain rotates between the two transmission gears. The traction chain drives the second mounting seat to rotate along the third mounting seat, thereby completing the position adjustment of the clamped component body by moving the second mounting seat, so that the component body can be moved to each work station, which is convenient for processing the component body and convenient for use.

[0095] The present invention also discloses a method for clamping an automobile wheel hub, comprising any of the above-mentioned automobile component clamping fixtures, the method comprising the following steps:

[0096] Step 1: Place the automobile wheel hub on the top of the support plate 2 and align two opposite sides of the automobile wheel hub in the height direction with the two third clamping frames 73 .

[0097] Step 2: Start the first motor 62, and the first clamping member 41, the second clamping member 42 and the third clamping member 73 move synchronously toward the direction close to the automobile wheel hub. The first clamping member 41 and the second clamping member 42 first abut against the circumferential side of the automobile wheel hub. The first motor 62 continues to rotate until the two third clamping members 73 abut against the opposite side surfaces in the height direction. The automobile wheel hub is limited by the first clamping member 41, the second clamping member 42 and the third clamping member 73 to complete the clamping process of the automobile wheel hub.

[0098] Step 3: When the clamped automobile wheel hub needs to be towed to move, the transmission gear 92 is rotated, and the transmission gear 92 drives the traction chain 93 to rotate along the two transmission gears 92. The traction chain 93 carries the second mounting seat 81 to move through the connecting component 10 to complete the movement of the automobile wheel hub.

[0099] Step 4: When the clamped automobile wheel hub needs to be rotated, start the second motor 82, and the second motor 82 drives the first mounting seat 61 to rotate along the second sliding frame 83. By rotating the first mounting seat 61, the automobile wheel hub is rotated under the limit of the first clamping member 41, the second clamping member 42 and the third clamping member 73, so as to complete the rotation processing of the automobile wheel hub.

[0100] The working principle of the present invention is described below:

[0101] When in use, the component body 3 is placed on the top of the support plate 2 and the narrower sides of the component body 3 are aligned with the two third clamping members 73 for clamping, and the first motor 62 is started. At this time, the first motor 62 drives the toothed column 63 to rotate, and under the action of the first toothed groove 6431 and the second toothed groove 721, the second connecting frame 643 and the third connecting frame 72 are synchronously driven to move toward the direction close to the toothed column 63. The second connecting frame 643 drives the sliding member 51 to slide toward the direction close to the first clamping member 41 and the second clamping member 42 through the first connecting frame 641. At this time, the sliding member 51 The pushing member 52 is driven to move by the first spring 54, and the pushing member 52 synchronously pushes the first clamping member 41 and the second clamping member 42 to slide in the direction close to the component body 3. When one of the first clamping member 41 and the second clamping member 42 contacts the component body 3, the first motor 62 continues to rotate. At this time, the hinged rod 53 rotates relative to the sliding member 51 and the pushing member 52, and the hinged rod 53 pushes the first clamping member 41 or the second clamping member 42 to continue to move in the direction close to the component body 3 until the first clamping member 41 and the second clamping member 42 both contact the component body 3. When the first clamping member 41 and the second clamping member 42 both contact the component body 3, the pusher 52 cannot move, the toothed column 63 continues to rotate, and the second spring 644 is stretched until the two third clamping members 73 contact the component body 3. During this period, the two second clamping members 42 and the two third clamping members 73 can contact the component body 3 from four sides around the component body 3, thereby increasing the clamping stability of the component body 3. By providing the second spring 644, the clamping tool can adapt to clamping component bodies 3 of different sizes, making it convenient to use. During clamping, only one driving force is required to drive the sliding member 51 to slide in the direction close to the first clamping member 41 and the second clamping member 42, making it convenient to use. After completing the clamping of the component body 3, in order to rotate the component body 3, the second motor 82 can be adjusted to drive the first mounting seat 61 to rotate, thereby completing the rotation process of the component body 3, making it easier to process the component body 3. The second mounting seat 81 is connected to the traction chain 93 through the connecting part 10. When the clamped component body 3 needs to be moved, the transmission gear 92 is adjusted to rotate, and the traction chain 93 rotates between the two transmission gears 92. The traction chain 93 drives the second mounting seat 81 to rotate along the third mounting seat 91, thereby completing the position adjustment of the clamped component body 3 by moving the second mounting seat 81, so that the component body 3 can be moved to each work station, which is convenient for processing the component body 3 and convenient for use.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
