The clamping mechanism includes a mounting part, a first clamping assembly and a positioning assembly. The clamping mechanism is moved to a position corresponding to the engine cylinder by a transfer robot arm. The clamping end of the first clamping jaw of the first clamping assembly is located on the clamping side, and the first driving member drives the clamping ends of the two first clamping jaws to move relative to each other to clamp the engine cylinder.

[0005] In one embodiment, the number of the positioning assemblies is at least two, and the positioning assemblies are spaced apart on the mounting member. The positioning columns of at least two of the positioning assemblies can be used to be inserted into the positioning holes of engine cylinder blocks of different models.

[0006] In one embodiment, the positioning assembly further includes a limiting member, which is mounted on the mounting member and located on the clamping side of the mounting member. The limiting member can abut against the positioning hole of the engine cylinder block. A movable hole is provided on the limiting member at a position opposite to the positioning hole. The positioning column moves relative to the mounting member so that the positioning column can move within the movable hole.

[0007] In one embodiment, the clamping mechanism for the engine further includes a pressing assembly, which includes an abutment member and an elastic member. The abutment member is arranged on the clamping side of the mounting member through the elastic member. The elastic member is used to apply an elastic force toward the engine cylinder body to the abutment member, and the abutment member is spaced apart from the limiting member.

[0008] In one embodiment, the clamping mechanism for the engine also includes a second clamping assembly, the second clamping assembly includes a second driving member, two oppositely arranged second clamping jaws and a telescopic driving member, the second driving member is installed on the mounting member, the second driving member is used to drive the two second clamping jaws to clamp relative to or away from each other, the telescopic driving member is set on the mounting member, the telescopic driving member is used to drive the second driving member to drive the second clamping jaw to extend and retract toward or away from the clamping side, so that the clamping end of the second clamping jaw can move to the clamping side of the mounting member.

[0009] In one embodiment, the clamping movement direction of the second clamping jaw intersects with the clamping movement direction of the first clamping jaw.

[0010] In one embodiment, the first clamping jaw is a strip-shaped structure, and one end of the strip-shaped first clamping jaw is the clamping end of the first clamping jaw; the second clamping jaw is a strip-shaped structure, and one end of the strip-shaped second clamping jaw is the clamping end of the second clamping jaw, and the distance between the clamping ends of the two second clamping jaws is greater than the width of the first clamping jaw.

[0011] In one embodiment, the clamping end of the second clamping end is the second clamping end, the other end of the second clamping end opposite to the second clamping end is the second mounting end, the second driving member includes a driving source, a linkage part and two driving parts, the two driving parts are rotatably connected to the linkage part respectively, the second mounting ends of the two second clamping jaws are rotatably mounted on the mounting member respectively, and the end of each driving part away from the linkage part is rotatably connected to a corresponding second clamping jaw, and the driving source is used to drive the linkage part to move toward or away from the clamping side.

[0012] In one embodiment, the clamping mechanism for the engine further includes a visual component, which is disposed on the mounting member and is used to obtain image information of the engine cylinder on the clamping side or the object to be clamped.

Since the clamping end of the first clamping jaw of the first clamping assembly is located on the clamping side, the clamping ends of the two first clamping jaws are driven by the first driving member to move relative to each other, and then the engine cylinder body is clamped by the clamping ends of the two first clamping jaws. Since the mobile driving member of the positioning assembly can drive the positioning column to move toward the clamping side, the positioning column is moved and extended into the positioning hole of the engine cylinder body. The clamping mechanism is driven to move by the transfer robot arm, and the first clamping jaw is used to cooperate with the positioning column to clamp the engine cylinder body. When the engine cylinder body is moved into place, the first driving member drives the clamping ends of the two first clamping jaws to move away from each other, and the mobile driving member drives the positioning column to retract. The above-mentioned clamping mechanism for the engine utilizes the cooperation between the first clamping claw and the positioning column to avoid shaking during the movement of the engine cylinder body, ensure the stability of the first clamping claw on the engine cylinder body, and further prevent the engine cylinder body from slipping due to shaking, thereby ensuring the safety of the engine cylinder body during movement.

[0015] Since the positioning column and the first clamping assembly are both arranged on the mounting part, the positioning column is controlled to extend and retract by the mobile driving part. If the position of the engine cylinder body clamped by the first clamping jaw causes the positioning column and the positioning hole on the engine cylinder body to not correspond to each other, or if the first clamping jaw clamps engine cylinder bodies of different models, causing the positioning column and the positioning hole on the engine cylinder body to not correspond to each other, it can still be ensured that the first clamping jaw can clamp the engine cylinder body without affecting the normal clamping work.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See Figure 1 and Figure 2An engine production apparatus 1 according to one embodiment of the present invention is used in an engine production process. Specifically, the engine production apparatus 1 includes a transfer robot arm 10 and an engine clamping mechanism 20. The engine clamping mechanism 20 is mounted on the transfer robot arm 10. The clamping mechanism 20 is used to clamp the engine cylinder block, and the transfer robot arm 10 is used to transfer the engine cylinder block, facilitating subsequent processing and assembly of the engine.

[0029] Please also refer to Figure 3 In one embodiment, the clamping mechanism 20 for the engine includes a mounting member 100, a first clamping assembly 200 and a positioning assembly 300, wherein one side of the mounting member 100 is a clamping side 110; the first clamping assembly 200 includes a first driving member 210 and two oppositely arranged first clamping jaws 220, the first driving member 210 is mounted on the mounting member 100, and the clamping ends of the first clamping jaws 220 are located on the clamping side 110 of the mounting member 100; the first driving member 210 is used to drive the clamping ends of the two first clamping jaws 220 to move relative to or away from each other, and the positioning assembly 300 includes a moving driving member 310 and a positioning column 320, the moving driving member 310 is provided on the mounting member 100, the moving driving member 310 is used to drive the positioning column 320 to move relative to the mounting member 100 toward the clamping side 110, and the positioning column 320 can be used to be inserted into the positioning hole of the engine cylinder block. The mounting member 100 is mounted on the transfer robot arm 10 .

[0030] The clamping mechanism 20 and engine production device 1 for the engine are as follows: the clamping mechanism 20 is moved to a position corresponding to the engine cylinder body by the transfer robot arm 10, so that the engine cylinder body is located on the clamping side 110 of the mounting part 100 of the clamping mechanism 20. Since the clamping end of the first clamping jaw 220 of the first clamping assembly 200 is located on the clamping side 110, the clamping ends of the two first clamping jaws 220 are driven by the first driving member 210 to move relative to each other, thereby clamping the engine cylinder body by the clamping ends of the two first clamping jaws 220. Since the moving driving member 310 of the positioning assembly 300 can drive the positioning column 320 to move toward the clamping side 110, the positioning column 320 is moved and extends into the positioning hole of the engine cylinder body. The clamping mechanism 20 is driven to move by the transfer robot arm 10, and the first clamping jaw 220 cooperates with the positioning column 320 to clamp the engine cylinder body. Once the engine block is in position, the first drive member 210 drives the clamping ends of the two first clamping jaws 220 to move away from each other, and the mobile drive member 310 retracts the positioning post 320. The aforementioned engine clamping mechanism 20 utilizes the cooperation between the first clamping jaws 220 and the positioning post 320 to prevent shaking during engine block movement, ensuring the stability of the first clamping jaws 220 clamping on the engine block, thereby preventing the engine block from slipping due to shaking and ensuring safety during engine block movement.

[0031] Since the positioning column 320 and the first clamping assembly 200 are both arranged on the mounting member 100, the positioning column 320 is controlled to extend and retract by the mobile driving member 310. If the position of the engine cylinder body clamped by the first clamping jaw 220 causes the positioning column 320 to be unable to correspond to the positioning hole on the engine cylinder body, or if the first clamping jaw 220 clamps engine cylinder bodies of different models, causing the positioning column 320 therein to be unable to correspond to the positioning hole on the engine cylinder body, it can still be ensured that the first clamping jaw 220 can clamp the engine cylinder body without affecting the normal clamping work.

[0032] See Figure 2 and Figure 3 In one embodiment, the clamping end of the first clamping jaw 220 is a first clamping end 222, and the other end of the first clamping jaw 220 opposite to the first clamping end 222 is a first mounting end 224. The first mounting end 224 is mounted on the mounting member 100 so that the first clamping end 222 is located on the clamping side 110 of the mounting member 100. The first driving member 210 is used to drive the first mounting ends 224 of the two first clamping jaws 220 to cause the first clamping ends 222 to move relative to or away from each other in a clamping motion. Specifically, the first mounting end 224 is rotatably disposed on a side of the mounting member 100 that is away from the clamping side 110. The first driving member 210 is used to drive the first mounting end 224 to cause the first clamping ends 222 to rotate relative to the mounting member 100, thereby achieving relative or away movement between the first clamping ends 222 of the two first clamping jaws 220.

[0033] In another embodiment, the first clamping jaws 220 may also be movably disposed on the mounting member 100 , and the first driving member 210 drives the two first clamping jaws 220 to move relative to each other to clamp the engine cylinder block.

[0034] In this embodiment, the first clamping jaws 220 clamp at the piston cavity of the engine block, and the first clamping ends 222 of the two first clamping jaws 220 clamp on the inner walls of two different piston cavities to achieve clamping of the engine block. To ensure that the first clamping assembly 200 can simultaneously grasp multiple models of engine blocks, the spacing between the first clamping ends 222 of the first clamping jaws 220 can be set to be within a range of 172mm-192mm in the clamping state. Specifically, the spacing between the outer walls of one first clamping jaw 220 facing away from the other first clamping jaw 220 in the clamping state is within a range of 172mm-192mm, which facilitates the clamping of multiple models of engine blocks.

[0035] In one embodiment, a strip-shaped clamping hole 120 is provided on the mounting member 100, and the length direction of the strip-shaped clamping hole 120 is the direction from one first clamping jaw 220 toward the other first clamping jaw 220, and the first clamping end 222 of the first clamping jaw 220 passes through the clamping hole 120 and is located on the clamping side 110, and the first mounting end 224 is installed on the other side of the mounting member 100 facing away from the clamping side 110, and the first clamping jaw 220 can clamp and move in the clamping hole 120 along the length direction of the clamping hole 120 toward or away from the other first clamping jaw 220. By providing the clamping hole 120, it is convenient to realize that the first clamping end 222 is located on the clamping side 110, and the first mounting end 224 and the first driving member 210 are both provided on the other side of the mounting member 100 facing away from the clamping side 110, so that on the clamping side 110, the first clamping assembly 200 only has the first clamping end 222, thereby avoiding the first mounting end 224 and the first driving member 210 interfering with the first clamping end 222 in clamping the engine cylinder block.

[0036] In one embodiment, at least two sensing elements 130 (such as Figure 4 Each first clamping jaw 220 corresponds to at least one sensor 130. The sensor 130 is used to detect the position of the first clamping jaw 220 relative to the mounting member 100, thereby determining whether the first clamping jaw 220 is in a clamping state. Specifically, the sensor 130 is installed at the clamping hole 120 and is located on the side of the first clamping jaw 220 facing away from the other first clamping jaw 220.

[0037] See Figure 2 、 Figure 4 and Figure 5In one embodiment, the number of the positioning assemblies 300 is at least two, and each of the positioning assemblies 300 is arranged at intervals on the mounting member 100, and the positioning columns 320 of at least two of the positioning assemblies 300 can be used to be inserted into the positioning holes of engine cylinders of different models. Specifically, the number of the positioning assemblies 300 is multiple. By using different positioning assemblies 300, it is convenient to adapt to the positioning holes on engine cylinders of different models, thereby improving the adaptability of the clamping mechanism 20. Since the positions of the positioning holes on engine cylinders of different models are different, after the first clamping assembly 200 clamps the engine cylinder, the positioning function is achieved by using the positioning columns 320 of the positioning assembly 300 corresponding to the engine cylinder.

[0038] In one embodiment, the positioning assembly 300 further includes a stopper 330, which is mounted on the mounting member 100 and located on the clamping side 110 of the mounting member 100. The stopper 330 is capable of abutting against a positioning hole in the engine block. A movable hole is defined on the stopper 330 at a position opposite the positioning hole, and the positioning post 320 is capable of moving within the movable hole when the positioning post 320 moves relative to the mounting member 100. During the clamping process, the stopper 330 abuts against the positioning hole on the end face of the engine block facing the clamping mechanism 20. This not only limits the extension position of the positioning post 320, but also cooperates with the first clamping assembly 200 to more stably clamp the engine block on the hook of the first clamping end 222 of the first clamping jaw 220, further preventing the engine block from shaking during the clamping process.

[0039] Specifically, the mounting member 100 further defines a mounting hole, into which the stopper 330 is mounted. The movable drive member 310 is mounted on the side of the mounting member 100 that faces away from the clamping side 110, while the positioning post 320 is capable of extending into the clamping side 110. The stopper 330 is located on the clamping side 110, ensuring that only the stopper 330 and the positioning post 320 are located on the clamping side 110. This ensures stable clamping and positioning, preventing other components from affecting the engine block.

[0040] In one embodiment, the clamping mechanism 20 for the engine further includes a pressing assembly 400, which includes an abutting member 410 and an elastic member (not shown). The abutting member 410 is disposed on the clamping side 110 of the mounting member 100 via the elastic member. The elastic member is used to apply an elastic force toward the engine block to the abutting member 410, and the abutting member 410 is spaced apart from the limiting member 330. In this embodiment, the pressing assembly 400 can elastically abut against the end surface of the engine block facing the clamping mechanism 20, while the limiting member 330 can rigidly abut against the end surface of the engine block facing the clamping mechanism 20, thereby ensuring the stability of the abutment against the engine block and thereby improving the stability of the clamping.

[0041] Specifically, the pressing assembly 400 further includes a support tube 420, which is disposed on the mounting member 100. The elastic member and the abutting member 410 are both disposed within the support tube 420, and the abutting member 410 is capable of extending and retracting within the support tube 420. Alternatively, a movable hole is formed on the mounting member 100, the elastic member is disposed within the movable hole, and the abutting member 410 is passed through the movable hole and is capable of extending and retracting within the movable hole.

[0042] See Figure 2 and Figure 3 In one embodiment, the mounting member 100 includes a mounting frame 140 and a mounting post 150 disposed on the mounting frame 140. The side of the mounting frame 140 facing away from the mounting post 150 forms the clamping side 110, and the side of the mounting post 150 facing away from the mounting frame 140 is capable of being mounted on the transfer robot arm 10. Specifically, the positioning assembly 300 and the first clamping assembly 200 are both disposed on the mounting frame 140. The pressing assembly 400 is also disposed on the mounting frame 140.

[0043] See Figure 2 and Figure 6 In one embodiment, the clamping mechanism 20 for an engine further includes a second clamping assembly 500. The second clamping assembly 500 is mounted on the mounting member 100 and is used to clamp the partition between the engine cylinders. In other embodiments, the second clamping assembly 500 can also be used to clamp other items that need to be clamped.

[0044] In this embodiment, the second clamping assembly 500 is disposed on the mounting post 150. Providing the mounting post 150 facilitates the installation of the second clamping assembly 500.

[0045] In the engine assembly process, a single clamping mechanism 20 is generally used. Each clamping mechanism 20 can only clamp one type of object. Consequently, multiple clamping mechanisms 20 are often required to implement the engine assembly process, resulting in high production costs and a large footprint. In this application, a first clamping assembly 200 is used to clamp engine blocks of different models, while a second clamping assembly 500 is used to clamp a partition, achieving the function of a single clamping mechanism 20 clamping different materials.

[0046] In one embodiment, the second clamping assembly 500 includes a second driving member 510, two oppositely disposed second clamping jaws 520, and a telescopic driving member 530. The second driving member 510 is mounted on the mounting member 100 and is used to drive the two second clamping jaws 520 to move relative to or away from each other in a clamping motion. The telescopic driving member 530 is mounted on the mounting member 100 and is used to drive the second driving member 510 to cause the second clamping jaws 520 to extend or retract toward or away from the clamping side 110, so that the clamping ends of the second clamping jaws 520 can move to the clamping side 110 of the mounting member 100. During the clamping process, the telescopic driving member 530 drives the clamping ends of the second clamping jaws 520 to extend and retract to the clamping side 110 of the mounting member 100 so as to align with the position of the partition on the clamping side 110. The second driving member 510 then drives the two second clamping jaws 520 to move relative to each other in a clamping motion, thereby clamping the partition. After use, the telescopic driving member 530 is used to drive the clamping end of the second clamping jaw 520 to retract and exit the clamping end to avoid affecting the clamping of the engine cylinder block by the first clamping assembly 200.

[0047] Specifically, the second clamping assembly 500 is mounted on the mounting post 150. A guide structure 540 is provided on the mounting post 150. The guide structure 540 guides in the direction of extension and retraction of the telescopic drive member 530, i.e., toward the clamping side 110. The second drive member 510 is mounted on the mounting post 150 via the guide structure 540. Furthermore, the guide structure 540 can be a slide rail or slider structure, or a slider slot structure, or other structure capable of guiding the movement of the second clamping assembly 500, thereby improving the stability of the movement of the second clamping assembly 500 relative to the mounting member 100.

[0048] In another embodiment, a second telescopic drive member may be further provided on the mounting member 100, and the second telescopic drive member is used to drive the clamping end of the first clamping jaw 220 to telescopically move to the clamping side 110. When the first clamping assembly 200 is required, the second clamping jaw 520 is retracted, and when the second clamping assembly 500 is required, the first clamping jaw 220 is retracted.

[0049] In one embodiment, the clamping movement direction of the second clamping jaw 520 intersects with the clamping movement direction of the first clamping jaw 220. Since the clamping movement direction of the second clamping jaw 520 intersects with the clamping movement direction of the first clamping jaw 220, this avoids the need to follow the clamping space caused by the first clamping jaw 220 and the second clamping jaw 520 clamping in the same direction, which can easily cause the first clamping jaw 220 and the second clamping jaw 520 to interfere with each other during the clamping process.

[0050] Specifically, the first clamping jaw 220 is a strip-shaped structure, with one end of the strip-shaped first clamping jaw 220 serving as the clamping end of the first clamping jaw 220. The second clamping jaw 520 is a strip-shaped structure, with one end of the strip-shaped second clamping jaw 520 serving as the clamping end of the second clamping jaw 520. Furthermore, the distance between the clamping ends of the two second clamping jaws 520 is equal to the width of the first clamping jaw 520. By utilizing the strip-shaped structures of both the first clamping jaw 220 and the second clamping jaw 520, mutual interference during the clamping process is further avoided, ensuring clamping stability.

[0051] See Figure 4 and Figure 6 In one embodiment, a retaining groove 160 is defined on the mounting member 100. The clamping end of the second clamping jaw 520 can extend through the retaining groove 160 to the clamping side 110 of the mounting member 100. Specifically, the retaining groove 160 is defined on the outer wall of the mounting member 100. When the clamping end of the second clamping jaw 520 is retracted, the hook of the clamping end of the second clamping jaw 520 can be retained within the retaining groove 160. The retaining groove 160 can be used to position and restrict the position of the second clamping jaw 520, ensuring the stability of the second clamping jaw 520 on the mounting member 100 when the second clamping jaw 520 is not in use. Furthermore, the retaining groove 160 is defined on the side wall of the mounting frame 140.

[0052] See Figure 2 and Figure 6 In one embodiment, the clamping end of the second clamping jaw 520 is a second clamping end 522, and the other end of the second clamping jaw 520 opposite to the second clamping end 522 is a second mounting end 524. The second driving member 510 includes a driving source 512, a linkage part 514 and two driving parts 516. The two driving parts 516 are rotatably connected to the linkage part 514 respectively, and the second mounting ends 524 of the two second clamping jaws 520 are rotatably mounted on the mounting member 100 respectively. The end of each driving part 516 away from the linkage part 514 is rotatably connected to a corresponding second clamping jaw 520. The driving source 512 is used to drive the linkage part 514 to move toward or away from the clamping side 110.

[0053] Specifically, the second driving member 510 is disposed between the two second clamping jaws 520. Furthermore, the second mounting end 524 and the second driving member 510 are both mounted on the side of the mounting member 100 facing away from the clamping side 110. In this embodiment, the second mounting end 524 and the second driving member 510 are both mounted on the mounting post 150.

[0054] During the clamping process, the driving source 512 drives the linkage portion 514 to move away from the clamping side 110, and then drives one end of the driving portion 516 connected to the linkage portion 514 to move away from the clamping side 110 through the linkage portion 514. Because the driving portion 516 is rotatably mounted on the second clamping jaw 520, and the second mounting end 524 is rotatably mounted on the mounting member 100, the driving portion 516 can pull the second clamping jaws 520 to rotate toward each other, so that the two second clamping ends 522 move toward each other, achieving the clamping effect. After clamping is completed, the driving source 512 drives the linkage portion 514 to move toward the clamping side 110, and then drives the two second clamping jaws 520 to rotate away from each other through the linkage portion 514, so that the two second clamping ends 522 move away from each other.

[0055] In another embodiment, the second driving member 510 may also be other structures. For example, the second driving member 510 drives the two second clamping jaws 520 to move relative to or away from each other to achieve a clamping effect.

[0056] See Figures 1 to 3 In one embodiment, the engine clamping mechanism 20 further includes a vision component 600 disposed on the mounting member 100. The vision component 600 is configured to capture image information of the engine cylinder or the object to be clamped on the clamping side 110. The vision component 600 facilitates more accurate determination of the positional relationship between the object to be clamped and the first clamping assembly 200 or the second clamping assembly 500, thereby improving clamping accuracy. In another embodiment, the vision component 600 may be omitted.

[0057] Specifically, the vision assembly 600 is disposed on the mounting post 150 of the mounting member 100.
