[0002] In the assembly process of the one-way clutch, the bushing is generally crimped to the inside of the starting gear by axial crimping. In the crimping assembly process of the crimped bushing, the existing crimping equipment performs crimping assembly in place by setting a downward pressing stroke. The problem is that if the bushing installation positioning is deviated or the bushing falls off accidentally, the judgment of crimping in place by setting a downward pressing stroke will result in the bushing not being crimped in place or being pressed empty, which affects the assembly accuracy and quality. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a crimping-in-place detection assembly device.

[0014] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0015] Attached Figure 2 For attachment Figure 1 Schematic diagram of the enlarged structure of area A in the middle. DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] As attached Figure 1As shown, a crimping in place detection assembly device is used for crimping the starting gear 2 and the bushing 3 of the one-way gear 1, comprising a gear positioning seat 4 for positioning the starting gear 2 in a radial limiting manner and a bushing crimping head 6 for installing the bushing 3 in an adsorption manner, wherein the bushing 3 corresponds to the starting gear 2 in the axial direction. The crimping device 9 is included, and the bushing crimping head 6 is provided with crimping power by the crimping device 9. The suction device 11 is included, and the interior of the bushing crimping head 6 is in a negative pressure state by the suction of the suction device 11. The gear positioning seat 4 is provided with an in-place detection part 15. When the bushing 3 is crimped inside the starting gear 2, the in-place detection part 15 is used to detect the assembly position to detect whether the bushing 3 is crimped and assembled to the correct position in the starting gear 2. The in-place detection part 15 is used to perform the in-place detection, which is based on the prior art that sets the crimping stroke to be crimped in place by default and adds an in-place detection. The in-place detection part 15 can accurately detect whether the bushing 3 is crimped in place, thereby avoiding the occurrence of inadequate crimping, empty pressure, etc. during bushing assembly, thereby improving assembly accuracy. In addition, the in-place detection is performed during the crimping process, and there is no need for visual inspection after crimping, thereby improving the crimping assembly efficiency.

[0018] A limiting column 5 is provided on the gear positioning seat 4, and the starting gear 2 is seated on the gear positioning seat 4 by being sleeved on the limiting column 5 with the tooth shank 21 facing downward. Due to the crimping assembly operation, it is only necessary to radially limit the starting gear 2 by the limiting column 5, and the gear positioning seat 4 supports the starting gear 2.

[0019] Since some one-way clutches need to crimp two or more bushings 3 inside the starting gear 2, instead of just one bushing, the one-way clutch assembly device of the present invention needs to perform in-place detection adaptation for the case where two or more bushings 3 are crimped, that is, the present invention includes a lifting drive unit 14 corresponding to the in-place detection unit 15, and the in-place detection unit 15 is driven by the lifting drive unit 14 to axially displace inside the starting gear 2. For the crimping assembly of two or more bushings 3, as shown in the attached figure, Figure 1 The vertical starting gear 2 and bushing 3 shown follow the principle of crimping from bottom to top in sequence, and the in-place detection part 15 is driven upward by the lifting drive part 14, so that the in-place detection can be performed when each bushing 3 is crimped, thereby ensuring the assembly accuracy.

[0020] Among them, the lifting drive part 14 is preferably a cylinder, which is installed at the bottom of the gear positioning seat 4, and its piston rod is set through the gear positioning seat 4. The in-position detection part 15 is installed on the top of the piston rod. In the utility model, the in-position detection part 15 is a pressure sensor facing the bushing crimping joint 6.

[0021] An air passage 45 is provided through the limit column 5 and the gear positioning seat 4. The internal space of the starting gear 2 between the bushing crimping joint 6 and the limit column 5 is connected to the external pressure balance through the air passage 45, thereby reducing the crimping resistance affected by the pressure and ensuring smooth crimping assembly operation.

[0022] The bushing crimping joint 6 is a cylindrical structure with its mouth facing upward and its bottom facing downward, and adsorption holes 60 are evenly distributed on its body. Its mouth is connected to an insertion pipe 7, and a pressure plate 61 is radially extended from the periphery of the insertion pipe 7. The bushing installed on the bushing crimping joint 6 is pressed against the pressure plate 61 by adsorption, and the pressure plate 61 provides the crimping force during crimping.

[0023] It should be noted that in order to ensure the functional integrity of the pressing plate 61 and to perform the crimping operation normally, its size relative to the bushing 3 has the following requirements:

[0024] As attached Figure 2 As shown, the diameter of the pressing plate 61 is larger than the inner diameter of the bushing 3 but smaller than the outer diameter of the bushing 3 .

[0025] More specifically, the driving end of the crimping device 9 is connected and installed with the top end of the pipe 7 through a flange 10, and a sealing gasket is arranged between the flanges for sealing to prevent air leakage.

[0026] More specifically, the air suction device 11 is connected to the docking port 8 on the pipeline 7 through a flexible tube.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
