Description

Technical Field

[0001] This utility model belongs to the field of machining technology and relates to a clamping fixture for machining angle holes in supports. Background Technology

[0002] A support component has two stepped holes with spatial angles that need to be machined. The axes of the two stepped holes are parallel, and the diameter of the hole on the front side is smaller than the diameter of the hole on the back side. Figure 1 As shown, a five-axis CNC milling machine or machining center is required to complete the machining by adjusting the C-axis angle. Ordinary three-axis milling machines with traditional clamping methods such as vises cannot complete the machining. Utility Model Content

[0003] This utility model provides a clamping fixture for machining angle holes in a support, which solves the machining of stepped holes with spatial angles on the support part by using a three-axis milling machine.

[0004] The present invention adopts the following technical solution:

[0005] A clamping fixture for machining angle holes in a support has a base 1 as its main body. The base 1 is a trapezoidal block structure with one side sloped. A groove is machined on the slope according to the shape of the support 2. The groove opens from one side of the slope. During clamping, the support 2 is inserted into the groove of the base 1 from the opening until its end face is close to the groove wall to position the stepped hole to be machined, which facilitates subsequent tool setting and machining. Threaded holes are made in the groove of the base 1 corresponding to the mounting holes at the four corners of the support 2. The support 2 is fixed in the groove by bolts. The inclination angle of the slope of the base 1 and the groove is set according to the spatial angle of the two stepped holes to be machined on the support 1, so that after the support 2 is installed in the groove, the axes of the two stepped holes to be machined are vertical and the smaller diameter end of the hole to be machined is upward. A through hole coaxial with the hole to be machined is made on the bottom of the base 1 corresponding to the position of the two stepped holes to be machined.

[0006] The beneficial effects of this utility model are: This utility model can complete hole machining using a three-axis machine tool, saving the cost of purchasing five-axis machining equipment, with high processing efficiency and improved processing capability of three-axis equipment.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.

[0013] A clamping fixture for machining angle holes in supports, such as Figures 2 to 4 As shown, the main body is the base 1; the base 1 is a trapezoidal block structure with one side sloped, and a groove is machined on the slope according to the shape of the support 2. The groove opens from one side of the slope. When clamping, the support 2 is inserted into the groove of the base 1 from the opening until its end face is close to the groove wall to locate the stepped hole to be machined, which facilitates subsequent tool setting and machining; threaded holes are made in the groove of the base 1 corresponding to the mounting holes at the four corners of the support 2. The support 2 is fixed in the groove by bolts; the inclination angle of the slope of the base 1 and the groove is set according to the spatial angle of the two stepped holes to be machined on the support 1, so that after the support 2 is installed in the groove, the axis of the two stepped holes to be machined is vertical and the small diameter end of the hole to be machined is upward; the bottom of the base 1 has a through hole coaxial with the hole to be machined, corresponding to the position of the two stepped holes to be machined.

[0014] During machining, first insert the support 2 into the slot from the opening of the slot on the base 1 until the end face of the support 2 is close to the slot wall, and fix the support 2 in the slot with bolts; with the base 1 facing up, use a three-axis CNC milling machine to clamp the side of the base 1, and after setting the tool on the top and side of the base 1, complete the machining of the small diameter sections of the two stepped holes; invert the base 1 so that the bottom face is facing up, clamp it again with a three-axis CNC milling machine and complete the tool setting, and complete the machining of the large diameter sections of the two stepped holes through the through hole on the bottom surface of the base 1.

[0015] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
