Description

Technical Field

[0001] This utility model relates to the field of machine tool electric spindle flange connection technology, specifically a machine tool electric spindle flange connection device. Background Technology

[0002] A machine tool electric spindle flange is a structure installed at the end of an electric spindle. It is mainly used to support and fix the motor rotor, house bearings, and sometimes provide a sealing function. When installing a machine tool electric spindle flange, a machine tool electric spindle flange connection device is required.

[0003] The machine tool electric spindle flange connection device is wrapped by the detachable semi-circular sleeve cover of the flange, and then locked by screws on the upper cover plate. This allows the two detachable semi-circular sleeve covers to wrap and hold the machine tool electric spindle body. When the two detachable semi-circular sleeve covers are spliced, the connection point lacks a corresponding reinforcing positioning mechanism, which makes the connection point prone to deformation and gaps.

[0004] Therefore, we propose a novel flange connection device for machine tool electric spindles to solve the above-mentioned technical problems. Utility Model Content

The upper cover is inserted into the upper part of the detachable semi-circular cover to limit and position the detachable semi-circular cover. The upper cover can be inserted into the detachable semi-circular cover to limit and position the detachable semi-circular cover, so that the two detachable semi-circular covers can be stably wrapped and clamped. The connection end of the two detachable semi-circular covers can be reinforced by the upper cover, which effectively improves the strength of the connection end. This avoids gaps caused by deformation and makes the connection tighter. The top elastic sealing mechanism is sleeved on the inner side of the upper end of the upper cover, and the top elastic sealing mechanism can seal the inner side of the upper end of the upper cover.

[0035] The positioning installation lower cover, the detachable semi-circular sleeve cover, and the reinforced positioning upper cover are fixedly connected by assembly long screws 4, which facilitates assembly.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the reinforced positioning cover includes a top cover shell 5. A top elastic sealing mechanism is fixedly connected to the inner circumference of the top cover shell 5. The inner side of the top cover shell 5 can be sealed to the external component through the top elastic sealing mechanism. Four side reinforcing rods 51 are symmetrically fixed to the lower sides of both ends of the top cover shell 5. The top cover shell 5 can be reinforced by inserting the side reinforcing rods 51. Assembly long screws 4 are installed on the inner sides of both ends of the top cover shell 5 for easy assembly. The top cover shell 5 is inserted into the detachable semi-circular sleeve cover through the side reinforcing rods 51, which effectively improves the strength of the splicing end of the detachable semi-circular sleeve cover, avoids gaps caused by deformation, and makes the connection tighter.

[0037] The detachable semi-circular cover includes a semi-circular clamping cover 3. The interior of the semi-circular clamping cover 3 has a flange cavity 33. The semi-circular clamping cover 3 can be sleeved on the periphery of the machine tool electric spindle body 1 through the flange cavity 33, so that it can be wrapped and clamped. The middle of the outer end of the semi-circular clamping cover 3 has an assembly screw hole 31. The semi-circular clamping cover 3 is installed with an assembly long screw 4 through the assembly screw hole 31, so that it can be installed by correspondingly passing through. On both sides of the assembly screw hole 31, at the edge end of the semi-circular clamping cover 3, there are side insertion rod holes 32. The semi-circular clamping cover 3 is installed on the side reinforcing rod 51 through the side insertion rod holes 32, so that it can be inserted to strengthen the strength and avoid gaps at the splicing end.

[0038] The positioning and mounting cover includes a bottom cover shell 2. The bottom cover shell 2 has a central cavity 42 in the middle, which can be limited to the periphery of the machine tool electric spindle body 1 for wrapping and connection. The upper sides of both ends of the bottom cover shell 2 have limit insertion holes 511 for corresponding installation and connection. The outer side of the limit insertion holes 511 is provided with corresponding mounting screw holes 41 on the bottom cover shell 2, so that the assembly long screws 4 can pass through for installation.

The bottom cover shell 2 is fitted with the assembly long screw 4 through the corresponding mounting screw hole 41, so that it can be connected and installed.

[0040] In use, the positioning and mounting lower cover can limit the movement around the machine tool electric spindle body 1. Two detachable semi-circular sleeve covers are clamped and wrapped around the machine tool electric spindle body 1, which can wrap, clamp, and limit the movement. The detachable semi-circular sleeve covers can wrap, clamp, and limit the movement above the positioning and mounting lower cover. The reinforcing positioning upper cover can limit the movement around the machine tool electric spindle body 1. The reinforcing positioning upper cover is inserted into the upper end of the detachable semi-circular sleeve covers. The reinforcing positioning upper cover can be inserted to limit the movement of the detachable semi-circular sleeve covers, so that the two detachable semi-circular sleeve covers can be stably wrapped and clamped. The connection end of the two detachable semi-circular sleeve covers can be reinforced by the reinforcing positioning upper cover, which effectively improves the strength of the connection end of the detachable semi-circular sleeve covers, avoids deformation and gaps, and makes the connection tighter. The top elastic sealing mechanism can seal the upper inner side of the reinforcing positioning upper cover.
