Description

Technical Field

[0001] The present invention relates to the field of automobiles, and in particular to a slide clamping mechanism. Background Art

[0002] With the continuous improvement of automated and intelligent factory equipment in the automotive industry, the conveying and positioning of car bodies has also achieved fully automatic positioning. On existing automotive automated production lines, the conveying roller bed conveying skids currently rely on roller bed sensors to sense and stop in place.

[0003] However, since the fully automatic workstation uses an industrial robot for operation, the accuracy of coarse positioning by the roller bed sensor alone is low, with a deviation of 1-2 cm in the X direction. This causes the car body to fall to the workstation positioning pin device and interfere with the deviation, resulting in inaccurate positioning, causing the fully automatic workstation to be unable to operate normally. Summary of the Invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a slide clamping mechanism that can effectively solve the problem of slide conveying positioning deviation and achieve precise positioning.

[0008] The driving gear includes two gears meshing with each other, the two gears being connected to the first clamping arm and the second clamping arm respectively, and being used to transmit the driving force of the motor drive assembly to control the movement of the first clamping arm and the second clamping arm;

[0009] The ends of the first clamping arm and the second clamping arm are provided with clamping contact end surfaces for contacting the slide;

[0010] When the motor drive assembly operates in the forward direction, it drives the drive gear transmission, so that the first clamping arm and the second clamping arm are closed to a fixed position; when the motor drive assembly operates in the reverse direction, it drives the drive gear transmission, so that the first clamping arm and the second clamping arm are separated from each other to an initial open position.

[0011] Preferably, a fixed guide plate is further included, and the driving gear is located inside the fixed guide plate.

In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components under a specific posture (as shown in the figures).

Specific embodiments

[0029] This embodiment provides a sled clamping mechanism, such as Figure 1 As shown, it includes a clamping portion and a fixed guide rail. The clamping portion is connected to the fixed guide rail 7, so that the slide clamping mechanism can move along the fixed guide rail 7 to achieve the purpose of transporting the slide to a specified position.

[0030] The clamping part is mainly composed of a motor drive assembly 1, a first clamping arm 2, a second clamping arm 3, a drive gear 4, and a fixed guide plate 5. Specifically, the motor drive assembly 1 contains a motor for providing driving force to control the clamping and releasing actions of the slide clamping mechanism. The motor drive assembly 1 is connected to the drive gear 4, and when the motor drive assembly 1 outputs torque, the drive gear 4 will rotate accordingly. The drive gear 4 includes two meshing gears, both located inside the fixed guide plate 5, and are respectively connected to the first clamping arm 2 and the second clamping arm 3. When the drive gear 4 rotates, the first clamping arm 2 and the second clamping arm 3 will move accordingly. The design of the fixed guide plate 5 can protect the drive gear 4, reduce wear, and at the same time play a limiting role to ensure accurate transmission.

[0031] The first and second clamping arms 2 and 3 are handle-shaped, connected at their bases to the drive gear 4. Their distal ends feature a clamping contact surface 6, which increases the contact area with the slide, reduces or prevents damage to the workpiece, and prolongs its service life. Preferably, the clamping contact surface 6 can be made of wool to provide a cushioning effect during clamping, reducing impact and damage to the workpiece, protecting the slide surface, and improving clamping stability. It should be noted that the clamping contact surface 6 can be made of other cushioning materials besides wool.

[0032] The following describes the working state of the slide clamping mechanism provided in this embodiment. After the horizontal conveying of the conveying station is roughly positioned in place, the slide clamping mechanism performs a clamping action. Specifically, the motor drive assembly 1 contains a motor, and the motor can drive the drive gear 4 to transmit when operating in the forward direction, so that the first clamping arm 2 and the second clamping arm 3 are closed and fixed in position, and the slide is locked to accurately reach the positioning position through the clamping contact end face 6. After the work station is completed, the slide clamping mechanism performs an opening action. Specifically, the motor contained in the motor drive assembly 1 starts to operate in reverse, driving the drive gear 4 to transmit, separating the first clamping arm 2 and the second clamping arm 3 to the initial open position, thereby achieving the purpose of precise positioning of the car body slide.

[0033] The clamping force is regulated by a controller within the motor drive assembly 1, automatically adjusting the clamping force based on the material of the sled to prevent indentations or damage to the sled surface caused by excessive clamping force. Typically, the adjustable range of the clamping force can be adjusted to suit different working conditions.

[0034] The slide clamping mechanism provided in this embodiment is a precision positioning clamping mechanism, which is driven by a motor. The gear transmission clamping force is three times the clamping force of the traditional cylinder drive, which can effectively lock the conveying slide to ensure the accuracy of the positioning tooling. The locking and positioning mechanism has a simple structure and is easy to install. It only requires regular maintenance. For example, cleaning and maintenance every quarter can extend its service life to ten years.

[0035] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this invention.
