Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, and in particular to the processing and manufacturing of plate-type parts. Background Technology

[0002] Products to be processed, such as Figure 1 and Figure 2 As shown, the product includes surface A, surface B, two symmetrical surfaces C, and two symmetrical surfaces D. Surfaces A and B are symmetrical vertically. Each surface of the product needs to be processed, so multiple clamping and positioning of the product are required. Multiple clamping is time-consuming and labor-intensive. In addition, multiple positioning of the product can easily affect the positioning accuracy of the product, which directly affects the processing accuracy of the subsequent products. Ordinary clamping can only clamp a single product at a time, which is inefficient for mass production.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a multi-process milling device. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a multi-process milling device with two sets of fixtures to meet the product processing requirements. The fixtures can be quickly disassembled and replaced to improve processing efficiency. The device can quickly and forcefully clamp the product to ensure that the product will not loosen or shift during the processing. It also has a foolproof design to avoid processing defects caused by incorrect clamping direction.

[0005] To solve the above-mentioned technical problems, the present invention provides a multi-process milling device, which includes a four-axis rotary table, a base plate, a base plate seat, a first clamping fixture, and a second clamping fixture. The base plate is mounted on the rotary table base and the tailstock's rotating disk, and the base plate seat is mounted between the two base plates. The base plate seat has four clamping surfaces, and the first and second clamping fixtures, which can be quickly assembled and disassembled, are mounted on the clamping surfaces of the base plate seat. The first clamping fixture includes a clamping base plate and a toothed fixture. The fixture base plate has at least two product reference surfaces on its boss, and grooves on both sides of the product reference surfaces. A toothed positioning block is installed in one of the grooves. The two sides of the toothed positioning block closest to the product are positioning surfaces. The positioning surfaces are toothed surfaces. Two adjacent products share one toothed positioning block. At least two toothed eccentric clamping components are installed in the groove on the other side. A Y-axis positioning block is also installed on the side of the boss outside the product reference surface. The upper end of the Y-axis positioning block is provided with a positioning surface on the side closest to the product. The positioning surface is higher than the product reference surface.

[0006] Preferably, the toothed eccentric clamping component adopts an eccentric cam bolt, and the clamp base plate is provided with screw holes that mate with the eccentric cam bolt.

[0007] Preferably, the eccentric cam bolt is made of brass.

[0008] Preferably, the fixture base plate and base plate seat are provided with opposite mounting holes, which can be quickly locked by bolts.

[0009] Preferably, the second clamping fixture includes an adapter plate, locating pins, a clamping plate, anti-misalignment pins, and locking bolts. The adapter plate base is provided with opposite mounting holes. Two locating pins are installed on the adapter plate. The clamping plate is provided with locating holes that mate with the locating pins. The clamping plate and the adapter plate are provided with opposite mounting holes. At least two horizontal reference surfaces for positioning products at each workstation are provided on the boss of the clamping plate. Two anti-misalignment pins for positioning products are installed on the horizontal reference surfaces. The clamping plate is threaded from the bottom surface upwards with locking bolts for directional locking of products.

[0010] Preferably, the base plate is composed of four base plates, which are vertically fixedly connected in sequence.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The first clamping fixture uses toothed positioning blocks and toothed eccentric clamping parts to position the product, which can quickly and powerfully clamp the product and ensure that the product will not loosen or shift during the processing.

[0013] The second clamping fixture is designed to prevent mistaken insertion and avoid machining defects caused by incorrect clamping direction.

[0014] Product processing only requires two sets of clamps, which greatly improves processing efficiency. The two sets of clamps can be quickly disassembled, quickly clamped, and quickly changed. That is, while one set of clamps is processing inside the equipment, the other set of clamps is clamping the parts outside. Attached Figure Description
