Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a motor with an external gear drilling and reaming pin hole tool, which includes a fixture base 1, a supporting seat 2, a motor pressing plate 3 and a supporting block 4.

Specifically, referring to fig. 2 and 3, the fixture base 1 is provided with a sliding groove, the sliding groove is arranged along the front-back direction, and the cross section of the sliding groove is a rectangular groove. The supporting seat 2 is located above the clamp base 1, a raised sliding block 16 is arranged at the bottom of the supporting seat 2, the sliding block 16 is a rectangular block, and the sliding block 16 is embedded in the sliding groove and can slide. Thus, the support base 2 is slidably disposed on the fixture base 1, and the support base 2 can slide along the front-back direction.

Further, in order to realize the positioning of the support seat 2 sliding to any position, a protruding positioning block 18 is arranged on the outer wall of one side of the support seat 2, and two sides of the positioning block 14 are respectively provided with a positioning component. The positioning component comprises a positioning bracket 5 and a transverse adjusting screw 6, the positioning bracket 5 is fixed on the clamp base 1, the transverse adjusting screw 6 penetrates through and is in threaded connection with the positioning bracket 5, and the two transverse adjusting screws 6 are positioned on the same straight line and respectively abut against two sides of the positioning block 18. The positioning bracket 5 is an L-shaped bracket, one side surface of the positioning bracket 5 is fixed with the clamp base 1 through a mounting screw, and the other side surface of the positioning bracket is vertically arranged and is perpendicular to the transverse adjusting screw 6.

The top of the supporting seat 2 is provided with a V-shaped supporting groove 11, and the opening of the supporting groove 11 faces upwards. The motor pressing plate 3 is arranged above the supporting groove 11, the motor pressing plate 3 and the supporting groove 11 are arranged up and down oppositely, and a containing space of the motor 9 is formed between the motor pressing plate 3 and the supporting groove 11. Two sides of the motor pressing plate 3 are respectively provided with two compression screws 8 in threaded connection with the clamp base 1, and the motor pressing plate 3 is connected with the clamp base 1 through the two compression screws 8. The two compression screws 8 are vertically arranged, each compression screw 8 penetrates through the motor pressing plate 3, the upper end of each compression screw compresses the motor pressing plate 3, and the lower end of each compression screw is inserted into the fixture base 1 and is in threaded connection with the fixture base 1. The threaded connection length of the compression screw 8 and the clamp base 1 is adjusted, so that the motor pressing plate 3 is adjusted to lift, and the clamping of motors 9 with different outer diameters is adapted.

Preferably, referring to fig. 2, one end of the motor pressing plate 3 is provided with a cylindrical closed mounting hole 13, and the other end of the motor pressing plate is provided with an open semi-closed mounting hole 14, one of the compression screws 8 penetrates through the closed mounting hole 13 to be in threaded connection with the clamp base 1, and the other compression screw 8 penetrates through the semi-closed mounting hole 14 to be in threaded connection with the clamp base 1. Thus, when the motor 9 arranged between the supporting groove 11 and the motor pressing plate 3 is clamped, only two compression screws 8 need to be screwed. When the motor 9 is disassembled, only two compression screws 8 need to be unscrewed, one end of the motor pressing plate 3, which is close to the closed mounting hole 13, rotates around the compression screws 8 to leak out of the motor 9, and then the motor 9 can be disassembled. When the motor 9 is disassembled, the motor pressing plate 3 does not need to be completely disassembled, so that the rapid press mounting and disassembling of the workpiece are realized, and the efficiency in processing is greatly improved.

In actual work, the lifting groove 12 lifts the joint of the output shaft of the motor 9 and the wheel shaft of the externally-hung gear 10, so that the bearing of the motor 9 is prevented from being damaged due to the fact that a bearing directly bears a large machining radial force.

Preferably, the front end of the clamp base 1 is provided with a vertical guide groove, and the guide groove is matched with the cross-sectional shape of the supporting block 4. The bottom of the guide groove is provided with a threaded hole extending downwards, the bottom of the supporting block 4 is inserted into the guide groove, and the supporting block 4 can only slide up and down under the constraint action of the guide groove. The vertical adjusting screw 15 is inserted into the threaded hole from below and is in threaded connection with the threaded hole. The upper end of the vertical adjusting screw 15 props against the bottom of the supporting block 4, and the vertical adjusting screw 15 rotates and goes up and down to drive the supporting block 4 to go up and down vertically.

Referring to fig. 1, 2 and 3, the clamping method of the tooling for drilling and reaming the pin hole of the external gear of the motor is that the supporting seat 2 is slid to a proper position according to the length of the external gear of the motor to be clamped, and the supporting seat 2 is fixed by a positioning part; loosening the two compression screws 8, rotating the motor pressing plate 3 to enable the supporting groove 11 to leak, placing the motor 9 in the supporting groove 11, rotating the motor pressing plate 3 back to cover the motor 9, and screwing the two compression screws 8 to enable the motor pressing plate 3 to compress the motor 9; then the height of the supporting block 4 is adjusted through the vertical adjusting screw 15, so that the lifting groove 12 lifts the joint of the output shaft of the motor 9 and the wheel shaft of the externally hung gear 10. After the clamping is finished, the tool spindle head 17 which is finally provided with a tool (a drill bit or a reamer) is started to rotate, and the pin hole machining is started.
