Description

A motor direct drive type square tooling plate automatic centering and positioning device

technical field

The utility model relates to a process equipment, in particular to an automatic centering and positioning device suitable for square tooling plates of different sizes.

Background technique

At present, it is one of the common production processes in industrial production to center and position the square tooling plate during the processing of the square tooling plate. With the continuous improvement of production technology, a large number of devices for centering and positioning square tooling plates have also increased. However, most of the automatic centering and positioning devices for square tooling plates used in the production process are not suitable for automatic centering and positioning of square tooling plates of different sizes. , and the production automation cannot be fully realized in the production process, manual participation is required, and the production efficiency is low. Therefore, in the production process, proceeding from the actual situation, research and development of an automatic centering and positioning device suitable for square tooling plates of different sizes conforms to the trend of industrial development and meets the needs of industrial production.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned background technology and provide an automatic centering and positioning device for square tooling plates. The characteristics of simple structure.

The technical scheme that the utility model adopts is as follows:

An automatic centering and positioning device for a square tooling plate directly driven by a motor, characterized in that the automatic centering and positioning device for a square tooling plate directly driven by a motor includes a strip-shaped fixing plate, which are respectively positioned on the left and right sides of the fixing plate through guide plates The left rack and the right rack can move toward each other along the length direction of the fixed plate, and the motor that applies driving force to the left rack and the right rack through the gears at the same time; the left end of the left rack is fixed to a left rack. As for the clamping arm, a right clamping arm is fixed at the right end of the right rack.

The gear is fixed on the motor shaft and positioned at the center of the fixed plate; the axis of the gear is perpendicular to the length direction of the fixed plate.

The left rack and the right rack are arranged parallel to each other with a certain distance; the gear is located between the left rack and the right rack and meshes with the left rack and the right rack at the same time.

Both the left rack and the right rack are circular racks; circular guide holes matching the circular racks are made on the guide plate.

The working principle of the utility model is: when the utility model starts to work, the motor drives the gear to rotate, and at the same time drives the left rack to move to the right and the right rack to move to the left. Drive the left clamping arm and the right clamping arm to move toward each other with the two racks; since the left clamping arm moves to the right and the right clamping arm moves to the left at the same distance, the gear axis is always between the left clamping arm and the right clamping arm The midpoint of the right clamping arm, so when the left clamping arm and the right clamping arm are respectively attached to the left edge and the right edge of the square tooling plate, the gear axis is the center point of the square tooling plate.

The beneficial effects of the utility model are: since the moving distance of the rack can be changed within a relatively large range, and the left clamping arm and the right clamping arm can move continuously, the utility model can satisfy the requirements of automatic clamping of square tooling plates of different sizes. The positioning needs to be found, and the method is simple and efficient; in addition, the structure of the utility model is also simple, easy to manufacture, and the cost is not high.

detailed description

Below in conjunction with the accompanying drawings of the description, the utility model will be further described, but the utility model is not limited to the following embodiments.

The motor direct drive type square tooling plate automatic centering and positioning device shown in the accompanying drawing includes a strip-shaped fixed plate 4, and the left rack 2-1 is positioned on the left side of the fixed plate through several left guide blocks 2-2, and the right The rack 3-1 is positioned on the right side of the fixed plate by several right guide blocks 3-2; the left and right guide blocks are respectively opened with guide holes that are conducive to the sliding of the left and right racks; visible in the figure: two left guides The block is opened with a guide hole arranged in the left and right directions (i.e. the length direction of the fixed plate). A right guide block also has a guide hole arranged in a left and right direction, and the backs of the two right guide blocks are respectively attached to and fixed on the front right side of the fixed plate and the two left guide blocks are separated by a certain distance. A left clamping arm 2-3 is fixed on the left end of the left rack, and a right clamping arm 3-3 is fixed on the right end of the right rack; form a right angle.

The motor 1-2 is fixed in the middle of the fixed plate through the gear seat; the motor applies driving force to the left rack and the right rack through the gear 1-3 fixed on the motor shaft. The left and right racks are arranged parallel to each other and at a certain distance (to provide space for the gears); the gears are located between the left and right racks and mesh with both. Obviously, due to the limited sliding range of the left rack and the right rack, only part of the rack needs to be made with teeth (it is not necessary to make all the teeth on the entire rack); the figure shows: the left rack is only made on the right side teeth, the right rack is only made with teeth on the left side.

It can be seen in the figure that the back of the gear seat 1-1 is fixed against the middle part of the fixed plate 4; two guide holes arranged in the left and right directions are also formed on the gear seat; The distance between the right racks is the same.

The left rack and the right rack can be circular cross-section racks or rectangular cross-section racks, and the guide holes on the guide blocks and gear seats are also made into suitable cross-sections; preferably, the left teeth Bar, right rack all select circular tooth bar for use, and the guide hole on the described guide block and gear seat then selects suitable circular guide hole for use.

When positioning square tooling plates of different sizes, the motor 1-2 drives the gear 1-3 to rotate continuously; the gear drives the left rack 2-1 to move continuously to the right, and at the same time drives the right rack 3-1 to continuously move to the left Movement; the left clamping arm 2-3 and the right clamping arm 3-3 move continuously with the two racks; the left rack and the right rack are driven to move the same distance during the rotation of the gears, that is, the left clamping arm moves to the right The distance moved is the same as that of the right clamping arm to the left; since the distance from the gear axis to the left clamping arm is always the same as the distance from the gear axis to the right clamping arm, it is possible to automatically center square tooling plates of different sizes Positioning; after the operation of the square tooling plate is completed, the motor reverses to reset the device.
