Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, and in particular to a machine tool guide rail and a pressing block structure. Background Art

[0002] CNC machine tools are general processing equipment currently used in the market. Linear guides are widely used as guide parts for coordinate axis operation on machine tools. Linear guides are fixed on the basic castings of machine tools. The castings of machine tools are processed with reference surfaces. One side of the guide is in contact with the reference surface. In order to make the guide contact with the reference surface firmly, a fastener is required on the other side to press the guide so that the guide can be close to the reference surface, thereby ensuring the straightness accuracy of the guide. At present, the most widely used fasteners are as follows: Figure 6 The shown pressure block structure, i.e., the pressure block has an inclined surface, and the machine tool casting needs to be processed with an inclined surface of the same angle to match the pressure block 7. When the pressure block is tightened by screws, the pressure block 7 will produce a displacement in the lateral direction along the inclined surface to clamp the guide rail. This structure must be processed into a deep and long groove with an inclined surface on the base casting. The deeper groove will cause stress concentration problems when the base casting is subjected to force, seriously affecting the rigidity of the parts. At the same time, the casting needs to partially thicken the outer wall thickness to adapt to the groove, making the casting structure complicated. It is also difficult to ensure the processing accuracy when processing a longer inclined surface, which will make it impossible for the pressure block to correctly clamp the guide rail and fail to achieve the expected purpose. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned background technical problems and to provide a machine tool guide rail and a pressure block structure.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] A machine tool guide rail and pressure block structure, including a base casting and a linear guide rail, wherein the linear guide rail is arranged on the base casting, and is characterized in that a groove one is provided on the base casting, and a groove two is further provided at the bottom of the groove one, the linear guide rail is detachably installed on the groove one, and a pressure block assembly is detachably installed in the groove two close to one side of the linear guide rail, and the pressure block assembly is used to clamp and fix the linear guide rail.

[0006] As a further solution of the present invention: the pressure block assembly includes a pressure block and a top block, the pressure block and the top block are both arranged in the second groove, the top block is close to one side of the linear guide rail, and the pressure block is close to one side of the top block.

[0007] As a further solution of the present invention: the pressing block is used to squeeze and limit the top block, and the pressing block is used to squeeze and limit the linear guide rail.

[0008] As a further solution of the present invention: a groove one is formed on one side of the pressing block close to the top block, and a protrusion protrudes outwardly from one side of the top block close to the pressing block to form a protrusion corresponding to the groove one, and the protrusion can be snap-fitted with the groove one.

[0009] As a further solution of the present invention: the first groove is an inclined groove, the protrusion is an inclined surface, and the pressure block can drive the inclined surface to generate displacement through the inclined groove to squeeze and limit the linear guide rail.

[0010] As a further solution of the present invention: the inclined groove has the same inclination as the inclined surface.

[0011] As a further solution of the present invention: a blind hole is vertically opened at the bottom of the second groove, a hole corresponding to the blind hole is opened through the pressing block, and the pressing block is tightened on the basic casting by a locking screw.

[0012] As a further solution of the present invention: the height of the pressing block is smaller than that of the top block, and the top block directly contacts the machining surface of the base casting.

[0013] As a further solution of the present invention, there is a gap of 2 to 3 mm between the pressing block and the machining surface of the base casting, so as to ensure that the pressing block can move downward to exert force on the top block and generate displacement.

[0014] As a further solution of the present invention: the pressing block assembly is made of metal.

[0015] Beneficial effects of the present invention: A machine tool linear guide and pressure block structure is a component, which is composed of a pressure block and a top block. The contact slopes of the pressure block and the top block make the top block close to the side of the linear guide, thereby achieving the purpose of clamping the linear guide. This invention does not require the base casting to be processed with a deep and long groove, simplifies the casting structure and processing, reduces the weight of the casting, and thus saves the cost of the machine tool.
