Therefore, various automobile companies have higher and higher requirements for motor vehicle manufacturing efficiency.

[0003] As one of the core components of a car, the engine has a relatively complex structure, so its assembly efficiency directly affects the manufacturing efficiency of the motor vehicle. The camshaft is one of the important parts of the engine as the valve timing mechanism of the engine. The camshaft holder is a mechanism for installing and fixing the camshaft. The camshaft and the cylinder head body are connected by an interference fit between the pin and the pin hole, so as to ensure that the camshaft can rotate in the holder shaft hole to open or close the valve. Usually, multiple holders need to be set on the cylinder head body to support and fix the camshaft, and the holders used to support different positions of the camshaft are different. In order to distinguish each holder, protrusions are provided at different positions on the outer edge of the holder, so that the structure of each holder is different. If the installation position of each holder is inaccurate, the camshaft cannot be installed normally. In order to install each holder to the correct position, it is often used to manually identify the characters on the holder to sort the installation position of the holder and place each holder on the cylinder head body in sequence, and then install and fix the holder on the cylinder head body.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0045] The camshaft holder is a mechanism for mounting and fixing the camshaft. Usually, a plurality of camshaft holders are required to be provided on the cylinder head body to support and fix the camshaft. It should be noted that, for the convenience of description, the camshaft holder is referred to as the holder 20 in this embodiment. Figure 1 and Figure 2 In order to fix the retainer 20, a positioning hole 21 is usually provided on the retainer 20 so that the retainer 20 can be fixed to the cylinder head body by a fixing member. Among the retainers 20 used, the outer edges of some retainers 20 are provided with protrusions 22, and the positions of the protrusions 22 are different on the retainers provided with the protrusions 22.

[0046] See also Figures 1 to 3In one embodiment of the present application, a retainer assembly and positioning device 10 is provided, comprising: a supporting and positioning body 110. A plurality of limiting spaces 120 are provided on the supporting and positioning body 110, and the shape of each limiting space 120 matches the shape of each retainer 20 one by one. The plurality of limiting spaces 120 are arranged correspondingly according to the arrangement of the plurality of retainers 20 on the cylinder head body, and each limiting space 120 is used to arrange and clamp each retainer 20.

[0047] When using the above-mentioned retainer assembly and positioning device 10, since a plurality of limiting spaces 120 are provided on the supporting and positioning body 110, the shape of each limiting space 120 matches the shape of each retainer 20 one by one. In other words, the shapes of each limiting space 120 are different, and only the corresponding retainer 20 can be placed in each limiting space 120, and the plurality of limiting spaces 120 are arranged correspondingly according to the arrangement of the plurality of retainers 20 on the cylinder head body. Therefore, workers can use the shapes of each limiting space 120 to place each retainer 20 in the corresponding limiting space 120. In this way, each retainer 20 can be sorted to conform to the order in which each retainer 20 is installed on the cylinder head body, without the need to sort by identifying the marks on the retainer 20 one by one by the naked eye. The retainer assembly and positioning device 10 effectively reduces the labor intensity of workers and improves work efficiency.

[0048] See also Figures 1 to 5 On the basis of the above embodiments, in one embodiment, the limiting space 120 includes a limiting hole 121, and the side walls of the limiting hole 121 are provided with a recessed notch 1211. The notch 1211 on the side wall of each limiting hole 121 is set at a different position, and the shape and position of each notch 1211 are matched one by one with the protrusion 22 on the outer edge of each retainer 20. Each limiting hole 121 is used to arrange and clamp each retainer 20. In this way, each retainer 20 is matched by the shape and position of the notch 1211 in the limiting hole 121, so that the retainers 20 are arranged in a prescribed order, which is convenient for the subsequent overall holding and installation of each retainer 20 on the cylinder head body at one time, and ensures that the order of each retainer 20 when the whole is placed on the cylinder head body meets the installation requirements. This process does not require manual identification of the marks on the retainers 20 to sort the retainers 20, which can effectively avoid errors caused by manual identification and improve work efficiency.

[0049] Optionally, when the outer edges of some of the retainers 20 are provided with protrusions 22, the side walls of the limiting holes 121 corresponding to the retainers 20 of this type are provided with notches 1211, and the position of the notches 1211 in the limiting holes 121 corresponds to the position of the protrusions 22 on the outer edges of the retainers 21. When the outer edges of some of the retainers 20 are not provided with protrusions 22, the side walls of the limiting holes 121 corresponding to the retainers 20 of this type are not provided with notches 1211. Alternatively, when the outer edges of all retainers 20 are provided with protrusions 22, and the positions of the protrusions 22 on the retainers 20 are different, correspondingly, the side walls of the limiting holes 121 matching the retainers 20 are provided with notches 1211 matching the protrusions 22.

The plurality of fourth clamping holes 11241 correspond to the plurality of third clamping holes 11231 one-to-one and surround a portion of the limiting hole 121.

[0052] In order to facilitate a clear understanding of the arrangement direction of the first clamping portion 1121, the second clamping portion 1122, the third clamping portion 1123 and the fourth clamping portion 1124 and the arrangement direction of the first clamping hole 11211, the second clamping hole 11221, the third clamping hole 11231 and the fourth clamping hole 11241 in this embodiment, Figure 3 For example, the first direction is Figure 3 Medium S 1 The direction indicated by Figure 3 Medium S 2 The direction indicated.

[0053] Thus, in the present application, the limiting hole 121 surrounded by the first clamping hole 11211 and the second clamping hole 11221 can be used to clamp the retaining frame 20 located on the intake side, and the limiting hole 121 surrounded by the third clamping hole 11231 and the fourth clamping hole 11241 can be used to clamp the retaining frame 20 located on the exhaust side.

[0054] Specifically, in this embodiment, the first clamping portion 1121 , the second clamping portion 1122 , the third clamping portion 1123 and the fourth clamping portion 1124 are all strip plates, and the second direction is the length direction of the strip plates.

A seventh clamping hole 11271 is provided on the side of the seventh clamping portion 1127 facing the sixth clamping portion 1126, an eighth clamping hole 11262 matching the seventh clamping hole 11271 is provided on the side of the sixth clamping portion 1126 facing the seventh clamping portion 1127, and the eighth clamping hole 11262 and the seventh clamping hole 11271 form a limiting hole 121. The sixth clamping hole 11261 and the eighth clamping hole 11262 are respectively disposed on two opposite sides of the sixth clamping portion 1126 .

[0057] See also Figures 1 to 3 On the basis of the above embodiment, in one embodiment, a plurality of support members 114 are provided on the support seat 111.

Under the support of the support members 114, the retaining frame 20 can be stably arranged in the limiting hole 121 to prevent the retaining frame 20 from falling off from the limiting hole 121.

[0058] Further, in one embodiment, the support member 114 includes two support pins 1141. The two support pins 1141 are arranged on the support seat 111 at a relative interval along the first direction, and the spacing between the two support pins 1141 is the same as the spacing between the two positioning holes 21 on the retaining frame 20. The two support pins 1141 are respectively inserted into the two positioning holes 21 on the retaining frame 20 to support the retaining frame 20.

The first elastic member 11411 provides a thrust along the length direction of the inner pin 11413 to the inner pin 11413. One end of the inner pin 11413 away from the first elastic member 11411 is protruded outside the outer pin 11412, and one end of the inner pin 11413 protruded outside the outer pin 11412 can be inserted into the positioning hole 21 on the retaining frame 20. The end surface of the outer pin 11412 away from the support seat 111 can abut against the positioning hole 21 on the retaining frame 20, which is used to support the retaining frame 20.

[0061] Specifically, in this embodiment, the first elastic member 11411 is a first spring.

[0062] See also Figure 5 and Figure 7 One embodiment of the present application further provides a retainer placement and pressing device 30, comprising: a base 310 and a plurality of clamping members 320. The plurality of clamping members 320 are correspondingly arranged on the base 310 according to the arrangement of each limiting space 120 in the retainer assembly arrangement device 10. The clamping members 320 can clamp the retainer 20 placed in the corresponding limiting space 120.

[0063] In the above-mentioned retainer picking and placing press-fitting device 30, since there are multiple clamping members 320, and the multiple clamping members 320 are correspondingly arranged on the base 310 according to the arrangement of each retainer 20 on the corresponding limiting space 120, the clamping members 320 can clamp the retainer placed on the corresponding limiting space. Therefore, when using the retainer picking and placing press-fitting device 30, the retainer picking and placing press-fitting device 30 is moved so that each clamping member 320 corresponds to each retainer 20 in each limiting space 120, and each clamping member 320 clamps the corresponding retainer 20 together. The retainer picking and placing press-fitting device 30 with multiple retainers 20 is moved to the cylinder head body, and each retainer 20 is placed at a corresponding position on the cylinder head body. In this way, it can effectively avoid the workers manually picking up the retainers 20 one by one and installing and fixing them on the cylinder head body, reducing the labor intensity of the workers while improving the work efficiency.

[0064] See also Figure 7 and Figure 8 On the basis of the above-mentioned embodiments, in one embodiment, the clamping member 320 includes a positioning portion 321 and a clamping portion 322 arranged relatively spaced apart along the third direction. The base 310 includes a first bottom plate 311 and a second bottom plate 312 arranged overlappingly. The positioning portion 321 is arranged on the first bottom plate 311, and the side of the positioning portion 321 used to press the retaining frame 20 is the positioning surface. The clamping portion 322 is arranged on the second bottom plate 312, and the side of the clamping portion 322 used to support the retaining frame 20 is the supporting surface. The second bottom plate 312 is provided with a through hole 3121 for each positioning portion 321 to pass through. A sliding mechanism 330 is provided between the first bottom plate 311 and the second bottom plate 312, and the second bottom plate 312 can slide relative to the first bottom plate 311 along the third direction. The second bottom plate 312 has a first state and a second state.

[0065] In order to facilitate a clear understanding of the relative sliding direction of the first bottom plate 311 and the second bottom plate 312 in this embodiment, Figure 7 or Figure 8 For example, the third direction is Figure 7 or Figure 8 Medium S 3 The direction indicated.

[0066] like Figure 7As shown, when the second bottom plate 312 is in the first state, the clamping portion 322 is close to the positioning portion 321, and the positioning surface and the supporting surface are respectively in contact with the two opposite end surfaces of the retaining frame 20. Figure 8 As shown, when the second bottom plate 312 is in the second state, the clamping portion 322 is away from the positioning portion 321, and the support surface is separated from the end surface of the retaining frame 20 that is away from the positioning surface.

[0067] Specifically, if Figure 7 As shown, when it is necessary to clamp the retaining frame 20, the second bottom plate 312 is moved along the third direction, and the clamping portion 322 is subsequently moved along the third direction toward the positioning portion 321, so that the distance between the positioning portion 321 and the clamping portion 322 is reduced. At this time, the second bottom plate 312 is in the first state, and the positioning surface on the positioning portion 321 and the supporting surface on the clamping portion 322 are respectively abutted against the two opposite end surfaces of the retaining frame 20, so that the retaining frame 20 is stuck between the positioning surface and the supporting surface.

[0068] Specifically, if Figure 8 As shown, when the holder 20 on the clamping member 320 needs to be put down, the second bottom plate 312 is moved away from the third direction, so that the distance between the positioning portion 321 and the clamping portion 322 increases. At this time, the second bottom plate 312 is in the second state, and the supporting surface on the clamping portion 322 does not contact the holder 20. After the holder 20 is no longer supported by the two opposite directions, the holder 20 can be detached from the clamping member 320.

[0069] See also Figures 7 to 9 On the basis of the above-mentioned embodiments, in one embodiment, the positioning portion 321 includes a first base 3211 and a pressing pin 3212. The first base 3211 is disposed on the first bottom plate 311 and passes through the through hole 3121. The pressing pin 3212 is disposed on a surface of the first base 3211 that faces away from the base 310. The end surface of the pressing pin 3212 that faces away from the first base 3211 is the positioning surface. In this way, when the second bottom plate 312 is in the first state, the pressing pin 3212 can abut against a surface of the retaining frame 20 that faces the base 310, and the supporting surface is supported on a surface of the retaining frame 20 that faces away from the base 310, so that the retaining frame 20 can be clamped between the pressing pin 3212 and the supporting surface, and then the retaining frame 20 disposed in the limiting hole 121 can be moved.

[0070] To avoid the pressing pin 3212 from rigidly contacting the end surface of the retainer 20, refer to Fig. 9 and Fig.10Specifically, in this embodiment, a first pin hole is provided on a surface of the first base 3211 facing away from the base 310, the first pin hole is used to place the pressing pin 3212, and the second elastic member 340 is placed in the first pin hole. One end of the second elastic member 340 is connected to the pressing pin 3212, and the other end of the second elastic member 340 is connected to the first base 3211. In this way, when the pressing pin 3212 abuts against the end surface of the retaining frame 20, the second elastic member 340 can effectively buffer the impact of the pressing pin 3212 on the end surface of the retaining frame 20.

[0071] Specifically, the second elastic member 340 is a second spring.

[0072] To prevent the holder 20 from shaking during the clamping process, please continue to refer to Fig. 9 and Fig.10 Further, two positioning pins 3213 are provided on the surface of the first base 3211 facing away from the base 310, and the two positioning pins 3213 are respectively located on both sides of the pressing pin 3212. The distance between the two positioning pins 3213 is the same as the distance between the two positioning holes 21 on the retaining frame 20. The two positioning pins 3213 are respectively inserted into the two positioning holes 21 on the retaining frame 20.

[0073] In order to prevent the positioning pin 3213 from being in hard contact with the hole wall of the positioning hole 21 and scratching the hole wall of the positioning hole 21 when the positioning pin 3213 is inserted into the positioning hole 21. Fig.10 In this embodiment, two second pin holes are provided on the side of the first base 3211 facing away from the base 310. The two second pin holes are respectively located on both sides of the pressing pin 3212, and the two second pin holes are used to place two positioning pins 3213 respectively. The third elastic member 350 is placed in each of the two second pin holes. One end of the third elastic member 350 is connected to the positioning pin 3213, and the other end of the third elastic member 350 is connected to the first base 3211.

[0074] Specifically, the third elastic member 350 is a third spring.

[0075] See also Figures 7 to 9On the basis of the above embodiment, in one embodiment, the clamping portion 322 includes a second base 3221 and a contact pin 3222. The second base 3221 is disposed on the second bottom plate 312. The second base 3221 and the first base 3211 are arranged relative to each other along the third direction. The contact pin 3222 is disposed on a side of the second base 3221 facing the first base 3211, and the contact pin 3222 is located on a side of the abutting pin 3212 away from the first base 3211, and a side of the abutting pin 3222 facing the positioning surface is the supporting surface. When the second bottom plate 312 is in the first state, the abutting pin 3222 is supported on an end surface of the retaining frame 20 away from the abutting pin 3212. When the second bottom plate 312 is in the second state, the abutting pin 3222 is away from the abutting pin 3212, and the abutting pin 3222 is separated from the end surface of the retaining frame 20 away from the abutting pin 3212.
