Description

Technical Field

[0001] This utility model relates to the field of milling machine equipment technology, specifically a multi-functional high-precision vise combination. Background Technology

[0002] An external hydraulic vise is a device used in milling machines and mold manufacturing. The double / hydraulic type can be used alone or in combination. Existing milling machine vises on the market are usually single-mouth vises, which have limited functions and cannot clamp and process large mold plates, causing difficulties in mold processing and manufacturing. Manual locking is inefficient and slow, and disassembly wastes a lot of time, which cannot meet processing needs.

[0003] The existing technology has the following drawbacks:

[0004] (1) The vises on the market have low manual locking efficiency and limited functions, making it impossible to complete mass production. If ten identical workpieces are to be processed, the center must be calibrated ten times, which is a complicated process and makes it difficult to guarantee accuracy.

[0005] (2) 100×50 plates cannot be clamped, thus restricting the function of the milling machine. The precision of slightly larger materials cannot be achieved. The mold plate with a length of 50mm cannot be placed, which restricts the function of the machine tool. The vise is helpless to clamp it.

[0006] (3) The existing vise makes it difficult to calibrate the minute meter and retrieve data, which seriously affects the accuracy and work efficiency. It takes a long time for manual labor and the efficiency of small-batch production is low.

[0007] (4) Manual clamping with traditional vises takes about 5 to 10 minutes, which wastes a lot of time.

[0008] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a multi-functional high-precision vise combination. Utility Model Content

[0009] The purpose of this utility model is to provide a multi-functional high-precision vise combination to solve the problems mentioned in the background art, such as low manual locking efficiency, limited functionality, inability to position and constrain the functions of machine tools, and difficulty in calibrating and retrieving data from minute counters.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional high-precision vise assembly, comprising a guide rail body, a fixed vise fixedly connected to the outer wall of the guide rail body, a fixed guide rod fixedly connected to the outer wall of the fixed vise, a sliding vise slidably connected to the outer wall of the fixed guide rod, a triangular guide rod slidably connected to the outer wall of the fixed vise and the sliding vise, a positioning nut provided on the outer wall of the sliding vise, a positioning bolt threadedly connected to the inner wall of the positioning nut, a first servo motor fixedly connected to the outer wall of the fixed vise, a first threaded rod fixedly connected to the output end of the first servo motor, a sliding clamp threadedly connected to the outer wall of the first threaded rod and slidably connected to the outer wall of the fixed vise, a locator detachably connected to the outer wall of the fixed vise, a connecting rod fixedly connected to the top of the sliding clamp, a limit rod fixedly connected to the top of the sliding clamp, a positioning rod slidably connected to the outer wall of the limit rod located on one side of the connecting rod, and a cylindrical clamp detachably connected to the outer wall of the positioning rod.

[0011] Furthermore, a second servo motor is provided at the top of the sliding clamp. The output end of the second servo motor is fixedly connected to a second threaded rod that is threadedly connected to the outer wall of the positioning rod. A connecting box is fixedly connected to the outer wall of the positioning rod. A connecting rod that is slidably connected to the outer wall of the connecting box is fixedly connected to the outer wall of the cylindrical clamp. A telescopic locking rod that is slidably connected to the inner wall of the connecting box is engaged with the outer wall of the connecting locking rod. A telescopic rod that is slidably connected to the outer wall of the connecting box is fixedly connected to the outer wall of the telescopic locking rod. A spring that is fixedly connected to the outer wall of the connecting box is sleeved on the outer wall of the telescopic rod. A pull block that is fixedly connected to one end of the telescopic rod is fixedly connected to one end of the spring.

[0012] Furthermore, the positioning bolts are symmetrically arranged about the central axis of the sliding vise, and the ends of the fixed guide rod and the triangular guide rod are fixedly connected to limit blocks.

[0013] Furthermore, the sliding clamp forms a telescopic structure with the fixed vise through the first threaded rod. The overall hardness of the first threaded rod and the second threaded rod is Rockwell hardness. The fixed vise and the sliding vise are both made of cast iron and heat-treated to a temperature above 100 degrees Celsius.

[0014] Furthermore, the positioning rod forms a telescopic structure with the limiting rod via the second threaded rod.

[0015] Furthermore, the outer wall contour of the pressing part of the connecting rod and the telescopic rod is inclined, and the outer wall contour of the engaging part of the connecting rod and the telescopic rod is flat.

[0016] Furthermore, a slot is provided at the connection point between the outer wall of the connecting box and the connecting rod.

[0028] like Figure 2 As shown, a second servo motor 13 is provided on the top of the sliding clamp 10.
