Description

Workpiece multi-material fixture

The invention relates to a multi-material fixture for a workpiece, in particular to a fixture structure that can prevent the stored materials of the workpiece from colliding or damaging teeth.

In the past, if you want to send the workpiece materials to the processing place for processing, you usually have to send the workpiece materials one by one to the processing place by manpower. After one workpiece material is processed, take out the workpiece material, and then put another unprocessed workpiece material Put it into the processing place for processing, but the problem of the traditional feeding method is that it is time-consuming and a waste of manpower, which is no longer in line with the current feeding method.

Therefore, in order to improve the shortcomings of the traditional feeding method, the industry has specially developed a mechanical arm for clamping materials. The front end of the mechanical arm is equipped with grippers, which use the grippers to clamp the workpiece material to the processing place for processing. However, the traditional mechanical arm , the clamping force of the jaws is not large, and it can only clamp a single and light workpiece material. Although the traditional mechanical arm can improve the problem of traditional manual feeding, the traditional mechanical arm cannot clamp a large amount of workpiece material at one time. Use The range is quite limited; in addition, the traditional mechanical arm is limited by the spring force, and the heavy workpiece material cannot be clamped by the traditional mechanical arm. Therefore, the effect of the traditional mechanical arm is still quite limited and does not meet the needs of the industry.

The invention relates to a multi-material fixture for workpieces, which mainly arranges the screw material parts in a plurality of rows by means of an array fixing mechanism, and presses the plurality of screw materials through a pressing plate to be connected with the array fixing mechanism. Arranged in the same inclined manner, and using the backing plate to be pulled away, there is a supporting space for the lower end of the screw head of the screw material, and then through the first supporting plate and the second supporting plate of the material supporting mechanism, the angle is steered through the power unit. Make the first pallet and the second pallet change from vertical to horizontal, and simultaneously make the horizontal first pallet and the second pallet respectively support the supporting space generated by the screw material, and use the power The unit controls the top pressure of the first pallet, the second pallet and the pressure plate, and holds up a large number of screw materials at one time, and then transfers them to the material box through the base shift, so as to achieve the feeding without collision or damage to the workpiece. efficacy.

In order to achieve the substantial performance of the above-mentioned purpose, the workpiece multi-material fixture disclosed by the present invention mainly includes an entire row of material fixing mechanism and a supporting mechanism arranged above the entire row of material fixing mechanism, wherein the entire row of material fixing mechanism includes the first rail and the second rail. track, and the end section of the first track forms a height difference structure, the height difference structure is equipped with a backing plate, and the backing plate is connected to a third pneumatic cylinder in a displaceable type; the supporting mechanism mainly includes: a The base is arranged on the longitudinal slide rail, and the longitudinal slide rail is also arranged on the horizontal slide rail through the connecting seat, so that the base can be moved up and down, front and rear, and left and right; an adjustment seat is fixedly connected with the base, and has A fixed base is fixed on the longitudinal slide rail, and is pivotally connected with a link block, which is fixedly connected with a power unit, and the power unit provides power to make the link block form a horizontal or inclined shape; a first supporting plate is arranged on The base is moved by its linkage, including a first pneumatic cylinder, a linkage arm group, and a pallet body. Connected to the supporting plate body, provide thrust through the first pneumatic cylinder, push the linkage arm group to expand and contract, and the linkage supporting plate body is supported towards the side end of the screw material; a material receiving plate is set on the side of the second track, so that The screw material is positioned by the top plate of the receiving plate; A pressing plate, arranged side by side with the material receiving plate at a distance, includes a fourth air cylinder and a pressing block, wherein the pressing block is connected with the jacking rod of the fourth air cylinder by a connecting piece, and is moved up and down by the fourth air cylinder position; a second pallet, which is set on the base and is displaced by its linkage, includes a second air cylinder, a first crank and a pallet; the front end of the push rod of the second air cylinder is movably connected to the first The middle section of the crank, and the open end of the first crank is fixed with a vertical support piece, which provides thrust through the second air cylinder, pushing the first crank to rotate at an angle, and the interlocking support piece changes from a vertical form to an angle form. To the lower end of the top material plate of the material receiving plate, and slightly protruding from the top material plate, so that the supporting piece is just located at the bottom of the screw head of the screw material; a material box is set on the outer edge of the end of the entire row of material fixing mechanism, including an opening upwards The box body and several frame rods arranged on the inner edge of the box body opening, and there is a gap between the frame rods for the screw material to be erected on the two frame rods; A large number of screw parts are picked up synchronously at one time, and driven to be transported to the material box, so as to achieve the feeding efficiency that the workpiece does not collide or damage the teeth.
