Description

Technical Field

[0001] The present application relates to the technical field of part positioning and processing tooling, and more specifically, to a zero-point positioning tooling for a flexible manufacturing system. Background Art

[0002] With the continuous development of modern industrial manufacturing technology, flexible manufacturing systems have been widely used in production lines. In flexible manufacturing systems, the positioning of pallet tooling is an important component to ensure the precise positioning of parts. However, when workers place pallet tooling, there are problems such as low positioning accuracy and tilted placement, which affects production efficiency and product processing quality. When the robot clamps the pallet tooling, it will shake, causing the parts on the pallet tooling to shift, which in turn causes errors in the processing accuracy of the parts. Therefore, it is of great significance to develop a zero-point positioning tooling. Utility Model Content

[0003] The utility model provides a zero-point positioning tool for a flexible manufacturing system, which ensures accurate positioning of the pallet tool through the cooperation of positioning holes, positioning pins, grooves and wedge blocks, thereby solving the problems of low positioning accuracy and complex operation of the pallet tool in the prior art.

[0004] The utility model is realized through the following technical solutions.

[0005] A zero-point positioning tool for a flexible manufacturing system, comprising:

[0006] A workbench, a mounting table fixedly arranged on the workbench, and positioning holes arranged on the mounting table;

[0007] A tray is placed on the workbench, and a ︹-shaped groove is provided on the right side of the tray. A pneumatic clamping rod is fixed in the groove. The tray is fixed in position by a positioning pin provided at the bottom end thereof and a positioning hole on the mounting table.

[0008] The positioning pins on the pallet match the positioning holes on the workbench to ensure that the positions of the pallet and the parts on the pallet are determined. When the machine clamps the workpiece, the pneumatic clamping holes on the manipulator clamp the pneumatic clamping rod, and the wedge block on the manipulator matches the ︹-shaped groove on the pallet to prevent the pallet from shaking during the clamping process.

[0009] In a further technical solution, in order to prevent the positions of parts on the pallet from being offset, a plurality of bolt holes are arranged on the pallet at equal intervals.

[0010] Furthermore, in order to facilitate manual movement of the pallet, a handle is fixedly installed on the left side of the pallet.

[0011] Furthermore, in order to facilitate recording of part information on the tray, a chip mounting hole is provided on one side of the pneumatic clamping rod, and a readable and writable chip is installed in the mounting hole.

[0012] Furthermore, in order to facilitate the pneumatic clamping hole on the manipulator to clamp the pneumatic clamping rod on the pallet, a limiting column is arranged around the positioning hole, and the limiting column is fixed on the workbench.

[0013] The manipulator has a certain thickness, and the limit column allows a certain distance between the bottom end of the pallet and the workbench, thereby facilitating the pneumatic clamping hole on the manipulator to clamp the pneumatic clamping rod on the pallet.

[0014] Furthermore, in order to accurately position the pallet on the workbench, at least two positioning pins are provided along the pallet from left to right.

[0015] The technical effects of the utility model are:

[0016] The present application positions the pallet tooling through the cooperation of positioning pins and positioning holes, thereby preventing the workers from shifting the position when placing the workpiece on the pallet, which would affect subsequent production and processing; when the robot clamps the pallet, the cooperation of the grooves and wedge blocks ensures that the position of the pallet is accurately positioned, enabling rapid positioning and clamping of the workpiece, thereby improving positioning accuracy and operating efficiency.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only embodiments of the utility model. For ordinary technicians in this field, other technical solutions can be obtained based on the provided drawings without paying creative work.

[0024] Example 1

[0025] Combination Figure 1~Figure 5 The utility model is a zero-point positioning tool for a flexible manufacturing system, comprising:

[0027] A tray 3 is placed on the workbench 1, and a ︹-shaped groove 4 is provided on the right side of the tray 3, and a pneumatic clamping rod 5 is fixedly provided in the groove 4. A positioning pin 2 is provided on the bottom end of the tray 3. A plurality of bolt holes 9 are provided at equal intervals on the tray 3, and a handle 10 is fixedly installed on the left side of the tray 3. Two positioning pins 2 are provided along the tray 3 from left to right.

[0028] The zero point positioning fixture is loaded and unloaded by Figure 1 The manipulator shown in the figure is completed, the manipulator 6 is arranged on one side of the workbench 1, and the manipulator 6 is provided with a wedge block 7 that matches the groove 4 through a clearance, and the wedge block 7 is provided with a pneumatic clamping hole 8.

[0029] During the implementation process, the staff lifts the pallet 3 by the handle 10 and places the pallet 3 on the workbench 1. The positioning pin 2 at the bottom of the pallet 3 is inserted into the positioning hole 102 on the workbench 1. There are two positioning pins 2 along the pallet 3 from left to right, which is convenient for positioning the pallet 3 and prevents the staff from tilting when placing the pallet, which makes it inconvenient for the manipulator 6 to clamp the pallet 3, affecting the production efficiency. Then, the staff places the part 13 to be processed on the pallet 3. The part 13 is fixed to the pallet 3 by screwing the bolt into the bolt hole 9 to prevent the part 13 from shaking on the pallet 3. When the production line is started, the wedge block 7 on the manipulator 6 cooperates with the ︹-shaped groove 4 on the pallet 3. In order to prevent the pallet 3 from shaking during the process of clamping the pallet 3 by the manipulator 6, thereby causing the part 13 on the pallet 3 to shift and cause subsequent processing errors, a pneumatic clamping hole 8 is provided on the wedge block 7 to clamp the pneumatic clamping rod 5 on the pallet 3, lift the pallet 3, and transport it to the next process for processing. The tray 3 and the parts thereon are quickly positioned and clamped, thereby improving positioning accuracy and operating efficiency.
