Detailed Implementation

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] like Figure 1-7As shown, an automatic gear-aligning device for an internal spline gear and an external spline shaft includes a base plate 1, a gear support seat 11 mounted on the base plate, and an elastic floating seat 2 installed inside the gear support seat. The elastic floating seat includes a fixed rod 21 fixedly connected to the base plate, a movable rod 22 sleeved on the outer side of the fixed rod, a spring 23 installed between the top of the movable rod and the fixed rod, a side pin 24 installed on the upper part of the fixed rod, and a guide groove 221 formed on the movable rod to cooperate with the side pin. When the movable rod moves up and down, the side pin slides relative to the guide groove to ensure the straightness of the movable rod's movement. A gear positioning block 3 is bolted to the top of the movable rod. A first positioning boss 31 is integrally formed on the bottom surface of the gear positioning block, and a first positioning recess 222 is formed on the top surface of the movable rod to cooperate with the first positioning boss, facilitating the replacement of the gear positioning block. A pair of internal positioning teeth 32 are integrally formed on the side wall of the gear positioning block for... The internal spline gear 4 has a tooth pair with the gear positioning block. To facilitate the insertion of the internal spline gear, the height of the internal positioning tooth can be maintained up to 5mm. After the internal spline gear is fitted onto the outside of the gear positioning block, the top surface of the internal tooth positioning block protrudes from the top surface of the internal spline gear to support the external spline shaft 5. The base plate is located on both sides of the gear support seat and supports 12 are installed. A linear reciprocating mechanism 6 is installed on the top surface of the supports. The linear reciprocating mechanism includes a cylinder 61 fixed to the support, a connecting block 62 fixed to the telescopic rod of the cylinder, a slider 63 fixed to the bottom of the connecting block, a guide rail 64 fixed to the support by the slider, and a shaft positioning block 7 fixed to the top of the connecting block. A second positioning recess 71 is opened at the tail of the shaft positioning block. A second positioning boss 621 that mates with the second positioning recess is machined on the connecting block. An external positioning tooth groove 72 is integrally formed at the end of the shaft positioning block facing the gear support seat for tooth pairing with the external spline shaft.

[0022] The specific working process and principle of this utility model are as follows: The internal spline gear is sleeved on the outside of the internal gear positioning block and precisely positioned by a pair of internal positioning teeth. The left cylinder is activated, and the left shaft positioning block extends to the middle of the base plate, placing the external spline shaft on the top surface of the internal gear positioning block. With the left shaft positioning block as a support, one side of the external spline shaft is engaged with the external positioning tooth groove. The right cylinder is activated, and the right shaft positioning block extends to the external spline shaft and cooperates with the left shaft positioning block to fix the external spline shaft directly above the internal spline gear. The press is activated, and when the press head presses the external spline shaft tightly, the cylinders on both sides are activated simultaneously. After the shaft positioning block retracts, the press head continues to press down to complete the assembly of the internal spline gear and the external spline shaft.
