Description

A planer tool holder with variable tool rake angle

technical field

The utility model relates to the field of tool holders, in particular to a planer tool holder with variable tool rake angle.

Background technique

In the machining process, the parameters of the rake angle of the tool will affect the sharpness and strength of the tool, and then affect the efficiency and effect of machining, which is very important. When studying the relationship between the rake angle of the planer and other parameters, it is necessary to change multiple rake angles for experiments. If the planer comes with a fixture, the rake angle can only be changed by grinding the rake face of the tool. Due to the hardness of the tool Very high, manual grinding is laborious and time-consuming, wastes tools, and there is a certain degree of danger, and it is difficult to accurately grasp the angle, which makes the experimental results have large errors.

Utility model content

The technical problem to be solved by the embodiment of the utility model is to provide a planer tool holder with variable tool rake angle, which is suitable for the tool installation port of a common planer.

In order to achieve the above purpose, the utility model discloses a planer tool holder with variable tool rake angle, which includes a first clamping block and a second clamping block, the side of the first clamping block has a first groove, and the first clamping block has a first groove. There is a second groove on the side of the two clamping blocks, the first and second grooves are relatively used for clamping the tool, and the clamping table on the planer clamps the clamping sides of the first and second clamping blocks respectively Therefore, the first and second clamping blocks clamp the tool, and the first and second grooves are inclined relative to the clamping side.

Preferably, the side surfaces of the first and second clamping blocks have protrusions and/or recesses, and the protrusions and/or recesses are arranged on the side surfaces where the first and second grooves are located.

Compared with the prior art, the utility model has the beneficial effects of:

The tool installed in the utility model can be normally installed on a common planer without any modification to the planer or the tool, and the applicability is extremely strong; the tool installed by the utility model can precisely control the rake angle of the tool and improve the Processing efficiency, effect and accuracy of experimental results; avoiding the time-consuming and labor-intensive and resource-wasting situation of manually grinding the rake face to change the rake angle of the tool in the past, by changing fixtures with different angles, the rake angle of the tool can be accurately changed; the structure is reliable, The installation is simple, and the knives are enclosed, which improves the safety when using by beginners such as students.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings of Fig. 1-Fig. 2 .

Referring to Fig. 1-shown in Fig. 2, a planer tool holder with variable tool rake angle includes a first clamping block 1 and a second clamping block 2, the side of the first clamping block 1 has a first groove 11, and the second clamping block 1 There is a second groove 21 on the side of the clamp block 2, and the first clamp block 1 and the second clamp block 2 are close together, so that the first groove 11 and the second groove 21 are butted together to form a tool for tool installation Through hole 3, the first groove 11 is inclined relative to the other side 13 without groove on the first clamping block 1, and the second groove 21 is inclined relative to the other side 23 without groove on the second clamping block 2, There is also a concave position 12 on the side of the first clamping block 1 having the first groove 11, and there is a protrusion 22 on the side of the second clamping block 2 having the second groove 21, and the protrusion 22 is embedded in the concave position 12 , so that the tight first and second clamping blocks will not slide relative to each other.

With reference to shown in Figure 3, the tool clamping table of bull planer comprises back plate 41, the clamping column 42 that is fixed on the back plate, screw 43, has clamping hole 44 on the clamping column 42, and cutter is installed in tool through hole 3, clamped by the first clamping block 1 and the second clamping block 2, the first clamping block 1 and the second clamping block 2 that are close to each other are installed in the clamping hole 44, and the screw 43 at one end of the clamping column 42 is screwed The first and second clamping blocks can be compressed between the screw 43 and the back plate 41 .

Through the embodiment of the utility model, the tool is installed on the planer, and the front angle of the tool is changed, and the value is accurate, reliable and stable, and the safety is high. By changing the fixture with different groove inclination angles, different tool front angles can be obtained. horn.
