Description

Technical Field

[0001] This utility model relates to the field of grinding machine processing technology, specifically to a positioning and fixing device for a grinding machine. Background Technology

[0002] Grinding machines are machine tools that use grinding wheels to grind the surface of workpieces. Generally speaking, most grinding machines use high-speed rotating grinding wheels for grinding. Therefore, grinding machines can process materials with high hardness or brittleness. As a result, grinding machines are widely used in the field of machining.

[0003] During the use of a grinding machine, it is generally necessary to grind some parts. In order to ensure the accuracy of the grinding process, it is necessary to position and fix the grinding machine parts to prevent them from deviating and affecting the processing effect. However, the dimensions of grinding machine parts are mostly different. If the positioning and fixing distance is difficult to adjust, it will easily cause inconvenience to the processing of grinding machine parts of different sizes. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning and fixing device for grinding machines, so as to solve the problem mentioned in the background art that the dimensions of grinding machine parts are mostly different, and if the positioning and fixing distance is difficult to adjust, it will easily cause inconvenience to the processing of grinding machine parts of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and fixing device for a grinding machine, including a worktable, with support legs fixed on both sides of the worktable, a fixing plate fixed at the middle position of the bottom end of the worktable, threaded rods installed on both sides of the fixing plate, threaded blocks sleeved on the outer side walls of the threaded rods, a first motor connected to one side of the threaded rods, and a fixing column fixed to the top of the threaded blocks.

[0006] Preferably, the threaded rods are symmetrically distributed about the vertical central axis of the fixed plate, and a threaded connection is formed between the threaded rods and the threaded blocks.

[0007] Preferably, a first reserved slot is provided at one end of the inside of the workbench, and a second reserved slot is provided at the other end of the inside of the workbench. Two sets of fixed columns are distributed at the top of the threaded block.

[0008] Preferably, one of the fixing posts passes through the first reserved slot and is adapted to the other, while the other fixing post has a slide rail running through its interior.

[0009] Preferably, a vertical plate is fixed to the top of the fixed column, a telescopic rod is installed on one side of the fixed column, a push plate is connected to one side of the telescopic rod, a second motor is installed at the middle position of one side of the push plate, and a clamping and fixing block is connected to one side of the second motor.

[0010] Preferably, a mounting plate is fixed to one side of the top of each of the two push plates, and mounting brackets are installed at both ends of the mounting plates. A reflective glass is installed on one side of one mounting plate, and an infrared rangefinder is installed on one side of the other mounting plate.

[0011] Preferably, a limiting groove is formed inside the vertical plate, and an adjusting column is inserted inside the limiting groove. A return spring is provided on the outer wall of the adjusting column. One side of the return spring is connected to one side of the vertical plate, and the other side of the return spring is connected to one side of the push plate. The adjusting columns are symmetrically distributed about the horizontal central axis of the push plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the positioning and fixing device for grinding machines not only improves the adjustment capability of the positioning and fixing device, but also improves the protection capability and distance measurement capability of the positioning and fixing device.

[0013] (1) By fixing the fixed plate at the middle position of the bottom of the workbench, the threaded rod is installed on both sides of the fixed plate and at the front end position, and the slide rail is installed on both sides of the fixed plate and at the rear end position, so that the vertical position of the threaded rod is adapted to the vertical position of the first reserved groove, and the vertical position of the slide rail is adapted to the vertical position of the second reserved groove. After starting the first motor, the threaded rod can be driven to rotate. At this time, the threaded rod and the threaded block are adapted to each other, so that the threaded block can travel along the threaded rod, thereby achieving the purpose of changing the distance between the two vertical plates. Two fixed columns are fixed at the top of the threaded block. One fixed column passes through the first reserved groove, and the other fixed column is adapted to the slide rail and its top passes through the second reserved groove, which plays a guiding adjustment role. Therefore, the overall adjustment capability is improved in the working process.

[0014] (2) After adjusting the distance between the two vertical plates, the grinding machine workpiece that needs to be positioned and fixed can be placed between the two clamping and fixing blocks. After starting the second motor, the clamping and fixing blocks will rotate, making it easy to find the correct position. Then, after starting the telescopic rod, the two push plates will move closer together to clamp and fix the grinding machine workpiece. When clamping, the elastic contraction of the return spring will allow the adjusting column to touch the side of the limit groove, thereby improving the buffer protection capability during the clamping and fixing process.

[0015] (3) By installing the mounting bracket, the mounting plate is installed on one side of the top of the two push plates respectively. An infrared rangefinder is installed on the side of one mounting plate, and a reflective glass is installed on the side of the other mounting plate. After the infrared rangefinder works, it can be used to detect the distance to the reflective glass, so as to better detect the clamping and fixing distance in a timely manner.
