Detailed Description
The invention will be further described with reference to specific embodiments shown in the drawings.
Referring to fig. 1-9, a quick centering tool for a semicircle of an engine shaft cover comprises a base 1, wherein a supporting block 3 for supporting a shaft cover 2 is arranged at the top of the base 1, a limiting block 4 is arranged on the base 1 on one side of the supporting block 3, a first driving mechanism for pushing the shaft cover 2 to the limiting block 4 is arranged on the base 1 on the other side, a positioning block 5 for positioning an inner circle of the shaft cover 2 is arranged on one side of the limiting block 4 close to the first driving mechanism, a positioning pin assembly movably inserted into the limiting block 4 is arranged on the positioning block 5, and an elastic element 6 is arranged between the positioning block 5 and the limiting block 4.
The two sides of the positioning block 5 are respectively provided with an arc surface 7 matched with the inner circle of the shaft cover 2, and the radius of the arc surface 7 is equal to that of the inner circle of the shaft cover 2. The positioning block 5 is of a bilateral symmetry structure, the elastic piece 6 is positioned on a symmetry line of the positioning block 5, and the positioning pin assembly comprises two pins 8 which are horizontally and symmetrically arranged by the elastic piece 6. The pin 8 and the pin hole of the positioning block 5 are in interference fit, and the pin 8 and the pin hole 13 of the limiting block 4 are in clearance fit with each other through a base hole. The pin 8 can play a role in guiding by matching with the pin hole 13 of the limiting block 4. Preferably, the elastic member 6 is a spring.
The first driving mechanism comprises a push plate 9 and a first oil cylinder 10 connected with the push plate 9. The first oil cylinder 10 is installed on one side, away from the positioning block 5, of the limiting block 4, a through hole 14 is formed in the supporting block 3, and a push rod of the first oil cylinder 10 sequentially penetrates through the limiting block 4 and the through hole 14 and is connected with the push plate 9. The base 1 at the two sides of the limiting block 4 is respectively provided with a pressing plate 11 and a second oil cylinder 12 which is correspondingly connected with each pressing plate 11 one by one. Two pressure plates 11 are used to press-contact both sides of the shaft cover 2. The cross-section of base 1 is the type of falling U structure, and second hydro-cylinder 12 passes base 1 top and extends to the base 1 inboard, and overall structure is compact.
The working principle is as follows:
when the device is in a non-working state, the elastic piece 6 pushes the limiting block 4 and the positioning block 5 away, but the pin 8 is still inserted in the pin hole 13 of the limiting block 4;
when the push plate 9 clamps the shaft cover 2, the shaft cover 2 is forced to move towards the positioning block 5; the inner circle of the shaft cover 2 is firstly pressed into the positioning block 5, so that the inner circle of the shaft cover 2 is mutually attached to the arc surface 7 of the positioning block 5; after the shaft cover 2 and the positioning block 5 are attached, the shaft cover continues to move towards the limiting block 4 and compress the spring 3 until the end face of the shaft cover 2 is in contact with the limiting block 4 and then is clamped tightly; the two pressing plates 11 press down simultaneously to press the two sides of the shaft cover 2 tightly.
The utility model discloses utilize the locating piece to advance line location fast to the interior circle of shaft cap, easy operation, it is efficient, can carry out accurate location to the semicircle orifice, solve the semicircle orifice because the influence of factors such as aperture, position degree causes the inaccurate problem in location, guarantee the transmission of size chain to guarantee the machining precision.
