DETAILED DESCRIPTION
[0030] The automobile steering reducer housing bearing and circlip assembly device comprises an assembly frame 1, a guide cylinder 19, a press fitting cylinder 2, a guide assembly 10 and a press fitting head 3 (see the appendix of the manual). Figure 1 and 2 ).
[0031] The assembly frame 1 is equipped with a press head 3 (see the appendix of the manual) through a press cylinder 2. Figure 1 and 14 The lower end of the press fitting head 3 is provided with a stepped press fitting surface 22; the circumferential surface of the stepped press fitting surface 22 is provided with a clamping plunger 23 (see the attached manual Figure 14 、 15 The purpose of providing the press fitting head 3 in this manner is: firstly, when the assembled bearing is inserted into the stepped press fitting surface 22 during operation, the bearing will be fixed to the press fitting head 3 with the cooperation of the clamping plunger 23; secondly, when the bottom end surface of the press fitting head 3 is used to compress the retaining spring, the bearing can be press fitted.
[0032] The support slide 4 is mounted on the assembly frame 1 below the press head 3 through a sliding rail; a push-pull cylinder 5 is mounted on the assembly frame 1 on one side of the support slide 4; the push-pull cylinder 5 is connected to the support slide 4 (see the attached manual). Figure 1 and 12 The support slide 4 is provided with a positioning seat 24 (see the attached manual). Figure 12 When the push-pull cylinder 5 is working, it can drive the support slide 4 to slide back and forth; when working, the reducer housing to be assembled can be placed on the positioning seat 24 in a unified posture.
[0033] A lifting plate 7 is installed above the support slide 4 through a symmetrically arranged lifting cylinder 6; an annular pressure ring 8 is installed in the middle of the lifting plate 7 (see the appendix of the manual). Figure 4 During operation, the lifting cylinder 6 can drive the annular pressure ring 8 to move up and down through the lifting plate 7, and press the reducer housing onto the positioning seat 24 through the annular pressure ring 8.
[0034] The assembly frame 1 on the outer side of the upper end of the annular pressure ring 8 is equipped with a feeding assembly 9 and a material guide assembly 10 (see the appendix of the manual). Figure 1 and 4 ); The material guiding component 10 is intermittently plugged into the upper end of the material guiding cylinder 19.
[0035] The feeding assembly 9 includes a feeding support plate 11, a pushing cylinder 12 and a feeding push plate 13; the feeding support plate 11 is fixed on the assembly frame 1 on the upper side of the annular pressure ring 8; the feeding push plate 13 is installed above the feeding support plate 11 through the pushing cylinder 12; the feeding push plate 13 is provided with a positioning hole 14 (see the appendix of the manual) Figure 15 ).
[0036] During operation, after the clamping ring is placed on the positioning hole 14 , the loading push plate 13 can move along the loading supporting plate 11 under the action of the pushing cylinder 12 .
[0037] The material guide assembly 10 includes a lifting cylinder 15, a material guide cylinder 19, a horizontal push cylinder A16, a horizontal push cylinder B20, an assembly fork 18 and a limit fork 21 (see the appendix of the manual). Figure 10 and 11 The assembly frame 1 is provided with a horizontal push cylinder A16 via a lifting cylinder 15; a guide cylinder 19 with a tapered inner hole is fixedly mounted on the horizontal push cylinder A16 via a lifting seat 17 and an assembly fork 18 (see the appendix of the manual). Figure 10 and 11 When working, the material guide cylinder 19 can be driven to move up and down under the action of the horizontal push cylinder A16 and the lifting cylinder 15.
[0038] A limit fork 21 is installed on the lifting seat 17 on one side of the guide cylinder 19 through a horizontal push cylinder B20; the limit fork 21 is inserted into the inner side of the guide cylinder 19 and then slidably connected with it (see the appendix of the manual). Figure 11 The purpose of providing the limiting fork 21 is to provide support for the retaining spring when the retaining spring falls into the guide barrel 19 during operation, thereby preventing the retaining spring from flipping over during the free fall into the guide barrel 19 and affecting the installation of the retaining spring.
[0039] When the automobile steering reducer housing bearing and circlip assembly device is working, the push-pull cylinder 5 first drives the support slide 4 to slide out, and at this time the reducer housing to be assembled can be manually placed on the positioning seat 24 in a unified posture. Then the support slide 4 drives the reducer housing to return to the position just below the annular pressure ring 8.
[0040] After the support slide 4 drives the reducer housing to reset and move to the specified position, the lifting cylinder 6 drives the annular pressure ring 8 to move downward through the lifting plate 7 to press and fix the reducer housing on the positioning seat 24.
[0041] After the annular pressure ring 8 fixes the reducer housing, the bearing to be assembled is manually inserted into the stepped pressing surface 22 of the press fitting head 3. At this time, the bearing will be fixed on the press fitting head 3 with the cooperation of the clamping plunger 23.
[0042] After the above work is completed, the press-fitting cylinder 2 drives the press-fitting head 3 to move downward to press-fit the bearing into the reducer housing, and then moves upward to reset. During this process, since the clamping strength between the bearing and the reducer housing is much greater than the clamping force of the clamping plunger 23, the press-fitting head 3 can easily separate from the bearing when it moves upward.
[0043] After the bearings are installed, the lower end of the guide cylinder 19, driven by the transverse push cylinder A16 and the lifting cylinder 15, passes through the annular pressure ring 8 and is inserted into the designated position of the reducer housing. The retaining ring to be assembled is then placed in the positioning hole 14. The loading push plate 13, driven by the push cylinder 12, moves along the loading support plate 11 to the top of the guide cylinder 19. At this point, the retaining ring falls under the action of gravity into the guide cylinder 19 and onto the stop fork 21.
[0044] After the circlip falls on the limit fork 21, the limit fork 21 will retreat in the horizontal push cylinder B20, and then the circlip will fall and be connected to the inner conical surface of the guide barrel 19. Then the press-fitting cylinder 2 drives the press-fitting head 3 to move downward, so that the press-fitting head 3 squeezes the circlip through the lower end surface and moves it down along the inner hole of the guide barrel 19 and finally press-fits it onto the reducer housing. In this way, the installation of the circlip is completed, and then the press-fitting head 3 is reset.
[0045] At this point, the automobile steering reducer housing bearing and circlip assembly device has completed the assembly of the bearings and circlips. Subsequently, the various components are reset and the assembled reducer housing is removed and replaced with a new reducer housing. The automobile steering reducer housing bearing and circlip assembly device can then enter the next working cycle.
[0046] The automobile steering reducer housing bearing and retaining spring assembly device has a compact structure and an ingenious design, and can complete the installation of the bearing and the retaining spring, thereby solving the problem of low production efficiency in the existing automobile steering reducer housing bearing and retaining spring assembly, and is particularly suitable for the needs of automobile steering reducer housing bearing and retaining spring assembly.
