Abstract

A method for manufacturing a transmission seat assembly, includes: providing an aluminum extruded body, which has a base, a connecting portion and an upper cover that are integrally formed from bottom to top. Two spaces are in communication with each other from left and right between an upper cover portion of the upper cover and a support portion. When the body is fixed on a first device, and a flat cutter is fixed by a second device, and one of the two devices is rotated by an angle to be fixed, such that the flat cutter can be moved into the spaces to gradually cut one end of the support portion by means of the to and fro relative motion of the first device and the second device, so as to form a right guiding portion having an inclined surface. The body is fixed reversely on the first device, and when the cutting operation is repeated again, a left guiding portion having another inclined surface that is symmetrically reverse to the right guiding portion is formed at another end of the support portion.

Description

Manufacturing method of transmission seat assembly

The present invention relates to a manufacturing method of a transmission seat assembly, in particular to a transmission seat assembly that can be cut and integrally manufactured and assembled on a linear actuator.

At present, many automated production factories use industrial robots, especially for certain special environments, such as: dangerous, harsh, monotonous, complex, delicate, heavy-loaded, or working environments that must be operated around the clock. Very suitable for the use of industrial robots. In terms of design, industrial robots must be able to be controlled and act freely within the scope of the working space, that is, they must have enough freedom under control. Therefore, by installing linear actuators with transmission belts and sliding rails on the X, Y, or Z axis of the industrial robot, the industrial robot can have three degrees of freedom in the X axis, Y axis, or Z axis, and the robot arm can Move in three directions.

At present, a common linear actuator for industrial robots is equipped with a transmission belt structure. The transmission belt structure is connected to a rotating shaft. The rotating shaft is driven by a servo motor to rotate, and the transmission belt structure drives the transmission seat assembly to move forward and backward. The system is connected with the robot arm to drive the robot arm to move. The above-mentioned transmission seat assembly is mainly composed of an upper cover, a dust-proof belt base, and a sliding block fixing base which are stacked from top to bottom in sequence and locked together, and the block fixing base is locked to the two sliding blocks. On the block, the toothed belt of the transmission belt structure is connected to the two ends of the slider fixing seat, so that when the toothed belt moves, the manufacturing method of the transmission seat assembly is driven to move.

However, since the above-mentioned transmission seat assembly is formed by a combination of casting or aluminum top cover, dust-proof belt base and sliding block fixing seat, it will not only need to be cast and processed separately, but also increase operation time and processing cost. . And in the manufacturing and assembly process, it is easy to deform and produce cumulative errors. For precision machinery, the occurrence of such errors will greatly reduce the precision of processed products. The integrated manufacturing method can effectively solve the above problems, but because the dust belt must pass through the enclosed space above the base of the dust belt, and both ends of the base of the dust belt need to pass through a guiding part with a slope. The guide can make the base of the dust-proof belt move smoothly to the left and right relative to the dust-proof belt. However, due to the general machining method, it is difficult to process in a closed space. Therefore, it is not currently possible to integrate The fabricated structure is manufactured in large quantities.

In view of this, in order to provide a structure that is different from the conventional technology and improve the above-mentioned shortcomings, the inventor has accumulated many years of experience and continuous research and development improvements, and thus the present invention was born.

One of the objects of the present invention is to provide a transmission seat assembly in which an aluminum extrusion blank and a flat cutting knife are relatively reciprocated for cutting, and the cutting directions of the aluminum extrusion blank and the flat cutting knife are at a specific angle The manufacturing method can solve the problem that the conventional one-piece transmission seat assembly is difficult to manufacture and process, and cannot be mass-produced, and can be quickly formed to effectively reduce production costs.

In order to achieve the above-mentioned purpose, the manufacturing method of the transmission seat assembly of the present invention includes the following steps: a. Provide an embryo body, the embryo body has an integrally formed base, connecting part and upper cover, the base is connected in a line Above the slider of the sex actuator, the connecting part is formed by extending upwards between the front and rear ends of the base. The upper cover includes an upper cover and a supporting part. The upper cover and the supporting part form a left and right communicating space. The supporting part is formed by the connecting part extending upward. b. Fix the embryo body on a first device, and fix a flat cutting knife with a second device, and at the same time place the first device or the second device in it One of them is fixed after rotating an angle, and then the first device and the second device are relatively reciprocated, so that the flat cutting knife extends into the space formed between the upper cover part and the support part to gradually cut one end of the support part, so that A right guide part that is an inclined surface is formed. And c. Reversely fix the embryo body on the first device, and then repeat the cutting action of the flat cutter in step b above to cut the other end of the support portion to form another inclined surface and oppositely symmetrical to the right guide One of the lead parts is the left lead part.

In implementation, the above-mentioned first device has a first clamp for clamping the embryo body; and the second device has a second clamp for clamping the flat cutter.

In implementation, the above-mentioned blank system is aluminum extrusion.
