The output end of the oil hydraulic cylinder faces upwards and is fixedly provided with a pressing rod, a pin shaft is fixed to the upper end side of the pressing rod, the pin shaft is rotationally connected with a pressing head, the pressing head is divided into two ends with the pin shaft as the center, the gravity of the two ends of the pressing head is unbalanced, and a check block is fixed to the position, above the small-gravity end of the pressing head, of the pressing rod. The rotatable pressing head is connected to the upper end of the pressing rod of the oil hydraulic cylinder, after the pressing head penetrates through the center hole of the motor end cover, the oil hydraulic cylinder drives the pressing rod to descend, and the pressing head automatically resets to clamp the motor end cover, so that the motor end cover can be stably pressed and positioned on the positioning seat in the process, and the edge of a sealing groove of the motor end cover cannot be crushed.

Description

TECHNICAL FIELD

[0001] The utility model relates to motor end cover processing technical field, concretely relates to a motor end cover processing frock. BACKGROUND

[0002] As Figure 1 As shown in the drawing, since the motor end cover 01 outside seal groove 02 needs to be processed, after frock positioning, the traditional clamping mechanism can only be pressed on the outside of the seal groove 02. Since the seal groove edge size is very small, the pressing position is less, and the small edge is easy to cause tight pressing, or the seal groove edge is pressed and broken by excessive pressure. And in the process of processing the seal groove, the cutter may interfere with the pressing block, causing the cutter to break, and the processing is unqualified. SUMMARY

[0003] The utility model discloses a motor end cover processing frock which overcomes the defects of the prior art.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A motor end cover processing frock, comprising a base plate, a positioning seat and a positioning pin are fixed on the base plate, the motor end cover to be processed is adaptively sleeved on the positioning seat and the positioning pin is inserted into the corresponding hole position of the motor end cover, an oil cylinder is fixed in the positioning seat on the base plate, the output end of the oil cylinder is upwardly arranged and fixed with a pressing rod, a pin shaft is fixed on the upper end side of the pressing rod, a pressing head is rotatably connected on the pin shaft, the pressing head is divided into two ends with the pin shaft as the center, the two ends of the pressing head are not balanced in gravity, and a stopper is fixed on the pressing rod and above the end with small gravity of the pressing head.

[0006] Further, the bottom of the positioning pin is connected with a spring.

[0007] The utility model adopts the above technical scheme, through the rotatable pressing head connected on the upper end of the pressing rod of the oil cylinder, after the pressing head passes through the center hole of the motor end cover, the oil cylinder drives the pressing rod to descend, and the pressing head automatically resets to clamp the motor end cover. The above process can stably press and position the motor end cover on the positioning seat, and the seal groove edge of the motor end cover will not be damaged. BRIEF DESCRIPTION OF DRAWINGS

[0008] The utility model will be further explained in detail in connection with the drawings and specific embodiments:

[0009] Figure 1 It is the sectional view for the motor end cover;

[0010] Figure 2 It is the schematic diagram of frock pressing state of the utility model;

[0011] Figure 3 It is the schematic diagram of the pressing head clamping state;

[0012] Figure 4 Fig. 2 is a schematic view of the pressure head in a reset state. DETAILED DESCRIPTION

[0013] As shown in Figures 2-4 The utility model discloses a motor end cover processing frock, including bottom plate 1, the fixed positioning seat 2 and the positioning pin 3 on bottom plate 1, the bottom of positioning pin 3 is connected with the spring. The motor end cover 9 of waiting for processing is suitably sleeved on positioning seat 2 and positioning pin 3 inserts the corresponding hole position in motor end cover 9, the oil cylinder 4 in positioning seat 2 is fixed on bottom plate 1, the output end of oil cylinder 4 sets up upwards and is fixed with pressure rod 8, the upper end side of pressure rod 8 is fixed with the pin shaft 7, and the pin shaft 7 is rotatably connected with the pressure head 6, and the pressure head 6 is divided into two ends with the pin shaft 7 as the center, and the two ends of pressure head 6 are not balanced in gravity, and the baffle is fixed on pressure rod 8 and above the gravity small one end of pressure head 6.

[0014] The utility model discloses clamping workpiece: oil cylinder 4 is in the loosening state, presses down pressure head 6 and makes it show vertical state ( hides in pressure rod 8), and the inner hole of motor end cover 9 is passed through pressure rod 8 and is clamped in positioning seat 2. Loosen pressure head 6, and under the location of baffle 5 under the action of gravity, pressure head 6 automatically overturns and shows horizontal state, and oil cylinder 44 drives pressure rod 8 to descend, and pressure head 6 is pressed tightly motor end cover 9.

[0015] The above describes the specific implementation of the utility model, but the person skilled in the art should understand that this is only an example, and the person skilled in the art can make various changes or modifications to this implementation without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
