A side connecting plate is fixed to the side wall of the upper spring base, which is detachably fixed to the base. A V-shaped protrusion protrudes from the top pressure rod, which is rotatably fixed to the side connecting plate. A circular block is rotatably fixed within the receiving hole of the V-shaped protrusion. The working side of the supporting spring base and the upper limit plate has a fixing step hole and a limiting hole for the spline end of the inner end section of the CG, as well as V-grooves I and II. A differential spring support groove is formed at the position of V-grooves I, and the differential spring is placed within it, its position perfectly aligned with the differential spring mounting groove of the inner end section of the CG. When the contact fixed to the lower end face of the top pressure rod is aligned with the proximity switch, the differential spring is installed, and the proximity switch controls the alarm device to output an alarm. Using this invention to install the differential spring on the inner end section of the CG eliminates the need for alignment; the differential spring is directly pressed onto the inner end section, saving time and effort, and has a wide range of applications. Furthermore, it prevents the differential spring from being missed during installation.

Description

Technical Field

[0001] This invention belongs to the field of CG inner end joint manufacturing and relates to an assembly device for a CG inner end joint differential spring. Background Technology

[0002] The current assembly of the differential spring in the CG inner end section uses manual spring clamps. The spring is held by hand and directly installed into the differential spring mounting slot of the CG inner end section. This method is difficult to position, requiring a long alignment time and causing operator fatigue. Missing differential springs on the production line go undetected. If inspectors fail to notice this later, and the spring is installed in a car by the customer, the CG inner end section inside the transmission may not be securely fixed. If the installer still doesn't discover the missing spring, the CG inner end section may detach from the transmission, causing the vehicle to lose power and posing a safety hazard. If the customer does discover the missing spring, they are required to install it promptly, preventing the vehicle from losing power, but this often results in customer complaints. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems existing in the prior art and to provide an assembly device for the differential spring of the inner end section of the CG. Using this device, the differential spring is installed on the inner end section of the CG without the need for alignment. The differential spring is directly pressed into the differential spring mounting groove on the inner end section of the CG. The operation is simple, time-saving, labor-saving, efficient, and has a wide range of applications. Moreover, it will not miss the differential spring, thus avoiding the risks caused by it.

[0004] To achieve the above objectives, the technical solution of the present invention is: an assembly device for a CG inner end differential spring, comprising a base, an upper spring base, a side support plate, a pressing mechanism, and a proximity switch;

[0005] The base is fixed to the side support plate or is integrally formed with the side support plate;

[0006] The pressing mechanism includes a side connecting plate with a length greater than that of the upper spring base, a pressing rod rotatably fixed to one end of the side connecting plate by a pin, a handle fixed to the end of the pressing rod, and a pressing circular block; the side connecting plate is fixed to the side wall of the upper spring base near the side support plate; a V-shaped protrusion protrudes from the end of the pressing rod away from the handle, the V-shaped protrusion has a receiving hole, and the pressing circular block is rotatably fixed in the receiving hole of the V-shaped protrusion by another pin;

[0007] The upper spring base is detachably fixed to the base. The upper spring base includes a supporting spring base and an upper limit plate fixed together. The working sides of the supporting spring base and the upper limit plate are respectively opened in the vertical direction with a fixed step hole whose lower end diameter matches the diameter of the lower part of the differential spring mounting groove of the inner end section of the CG and whose upper end diameter is larger than the spline end diameter of the inner end section of the CG, and a limiting hole whose diameter is not smaller than the upper end diameter of the fixed step hole. The two also have V-grooves I and II on their working sides that match the V-shaped protrusion and the top-connecting circular block of the pressing mechanism. The positions where V-grooves I and II connect with the fixed step hole and the limiting hole are provided with V-shaped protrusion and limiting stops of the top-connecting circular block. A differential spring support groove is opened at the position of V-groove I on the upper end face of the supporting spring base. The differential spring is placed in the differential spring support groove, and its position is exactly aligned with the differential spring mounting groove of the inner end section of the CG in the fixed step hole and the limiting hole.

[0008] The proximity switch is mounted on a support block fixed to the side support plate; the contact of the proximity switch is fixed on the lower end face of the pressure rod; the output end of the proximity switch is connected to the alarm device; when the contact is directly opposite the lower proximity switch, the pressure mechanism pressure differential spring is installed, and the proximity switch controls the alarm device to output an alarm.

[0009] More preferably, the specific structure for detachably fixing the upper spring base to the base is as follows: two positioning posts are fixed or integrally formed at the end of the upper surface of the base away from the working side, and a baffle is fixed on the side wall of this end; a top-connecting bolt is threaded onto the baffle; two positioning holes are opened on the bottom surface of the spring base to mate with the positioning posts on the base, and a positioning groove matching the top-connecting bolt on the base is opened on the side wall of this end; the two positioning holes of the spring base fit onto the two positioning posts on the base, the top-connecting bolt on the base is abutted and fixed in the positioning groove of the spring base, and the side connecting plate abuts against the side support plate. The fixing structure is simple and reliable, easy to install and disassemble the upper spring base, and does not affect the fixing of other components.

[0010] More preferably, the alarm device is a buzzer and / or a light display.

[0011] More preferably, the pressing mechanism further includes a rotary motor or a rotary cylinder; the rotary motor or rotary cylinder drives the handle to rotate, and the proximity switch also controls the rotary motor or rotary cylinder to run in reverse, driving the pressing rod to rotate back to its original position.

[0012] In use, insert the splined end of the CG inner end section into the fixed step hole and limit hole of the upper spring base. Place the differential spring in the differential spring support groove of the upper spring base. Manually or electrically drive the top pressure rod of the top pressure mechanism to rotate until the top circular block of the top pressure mechanism contacts the differential spring. The differential spring moves, and after the C-shaped opening of the differential spring contacts the differential spring support groove on the CG inner end section, it is first stretched open along the differential spring support groove under the action of the top pressure, and then automatically retracted under the action of the differential spring elasticity until the entire differential spring is engaged in the differential spring support groove of the CG inner end section. When the contact at the lower end of the top pressure rod is aligned with the lower end proximity switch, the proximity switch controls the alarm device to output an alarm, and at the same time, the top pressure rod of the top pressure mechanism rotates in the opposite direction to return to its original position; installation is complete. For CG inner end sections of different models and sizes, simply replace the upper spring base with the corresponding model. The device of this invention allows for the installation of differential springs on the inner end section of the CG without the need for alignment. The differential springs are directly press-fitted into the differential spring mounting slots on the inner end section of the CG, making the operation simple, time-saving, labor-saving, efficient, and applicable to a wide range of situations. Furthermore, it prevents the differential springs from being missed, thus avoiding the risks associated with this. Attached Figure Description
