On the one hand, the versatility of the device is poor, and it is difficult to adapt to workpieces of different shapes or heights (especially special-shaped workpieces). Each operation can only process one workpiece, resulting in the need to frequently replace different clamping devices according to the workpiece during the production process, which affects production efficiency.

[0028] Application Overview

[0029] In the field of manufacturing, it is usually necessary to use a clamping device to clamp the workpiece during the production process to assist the operating equipment in performing corresponding operations on the workpiece, such as welding. Due to the wide variety of workpieces involved in the production process and their different structural shapes, it is usually necessary to design a matching clamping device specifically for each type or category of workpieces. However, common clamping devices have poor versatility and are difficult to adapt to workpieces of different shapes or heights. Each operation can only handle the same workpiece and satisfactorily meet production requirements, especially the clamping operation requirements for special-shaped workpieces. In order to meet the production and processing needs of a variety of workpieces, it is necessary to equip clamping devices of various specifications, and replace different clamping devices according to the shape specifications of the workpiece during the production process, which not only affects production efficiency, but also causes equipment costs to rise. Therefore, it is necessary to develop a clamping device with greater versatility.

[0030] Some embodiments of the clamping device in the technical solution of the utility model are provided below.

[0031] In one embodiment of the present utility model, a pressing device 100 is provided, such as Figure 1 As shown, the clamping device 100 includes a mounting base 1, a lifting mechanism 2, a first clamping mechanism 3, a second clamping mechanism 4 and a transmission mechanism 5. The mounting base 1 plays a supporting role; the lifting mechanism 2 is connected to the mounting base 1 and can move relative to the mounting base 1 along a first direction, for example Figure 1 The lifting and lowering movement is shown in the height direction; the first clamping mechanism 3 and the second clamping mechanism 4 are movably connected to the mounting base 1 and are spaced apart in the second direction, wherein the second direction is perpendicular to the first direction; the transmission mechanism 5 is rotationally connected to the lifting mechanism 2, and the transmission mechanism 5 is respectively in transmission cooperation with the first clamping mechanism 3 and the second clamping mechanism 4. When in use, the transmission mechanism 5 can transmit power to the first clamping mechanism 3 and the second clamping mechanism 4 under the drive of the lifting mechanism 2, so that the first clamping mechanism 3 and the second clamping mechanism 4 slide in the same direction or in the opposite direction in the first direction, so as to respectively clamp the corresponding workpieces below; since the first clamping mechanism 3 and the second clamping mechanism 4 can adjust the relative height by reverse sliding, they can each adapt to workpieces of different heights and shapes, and can meet the clamping operation requirements of special-shaped workpieces.

[0032] Among them, Figure 1 and Figure 2As shown, during the clamping operation, in the initial stage, the first clamping mechanism 3 and the second clamping mechanism 4 are both located at the upper initial position, and there is a certain height difference between them and the corresponding workpiece; when the lifting mechanism 2 drives the transmission mechanism 5 to descend, when the transmission mechanism 5 does not rotate relatively, the first clamping mechanism 3 and the second clamping mechanism 4 are synchronously descended with the transmission mechanism 5, that is, the first clamping mechanism 3 and the second clamping mechanism 4 slide in the same direction; when the transmission mechanism 5 rotates relatively, the first clamping mechanism 3 and the second clamping mechanism 4 move in the opposite direction, that is, one slides upward and the other slides downward, for example Figure 2 In the example, when the first clamping mechanism 3 and the second clamping mechanism 4 slide downward until the first clamping mechanism 3 first contacts the workpiece 1 61, the first clamping mechanism 3 slides upward after receiving the reaction force of the workpiece 1 61, and the transmission mechanism 5 rotates relatively, thereby causing the second clamping mechanism 4 to continue to slide downward. When the second clamping mechanism 4 contacts the corresponding workpiece 2 62, a movement process similar to the aforementioned reverse sliding occurs; in the above process, the overall same-direction sliding and relative reverse sliding of the first clamping mechanism 3 and the second clamping mechanism 4 are combined to continuously reduce the height difference between the first clamping mechanism 3 and the second clamping mechanism 4 and their respective corresponding workpieces, until the first clamping mechanism 3 clamps the corresponding workpiece 1 61 and the second clamping mechanism 4 clamps the corresponding workpiece 2 62, the lifting mechanism 2 and the transmission mechanism 5 stop moving and maintain the current state, so that the first clamping mechanism 3 and the second clamping mechanism 4 simultaneously maintain the state of clamping the workpiece, completing this clamping operation.

[0033] It can be understood that in the prior art, when a set of driving mechanisms drives multiple clamping mechanisms at the same time, the multiple clamping mechanisms can only realize synchronous movement. If it is necessary to realize independent movement of multiple clamping mechanisms, each of them needs to be provided with a set of driving mechanisms. In this embodiment. Through a set of lifting mechanism 2 and transmission mechanism 5, the first clamping mechanism 3 and the second clamping mechanism 4 can be lifted and lowered synchronously, and the first clamping mechanism 3 and the second clamping mechanism 4 can also generate relative reverse movement, so that the height of the first clamping mechanism 3 and the second clamping mechanism 4 can be adjusted according to the height of the workpiece by using a combination of the two movements, so that they can finally adapt to the height of the corresponding workpieces.

[0034] It should be noted that, in practical applications, the clamping device 100 is usually installed on a special support platform. According to specific operation requirements, the workpiece can be directly placed on the support platform at a position corresponding to the first clamping mechanism 3 and the second clamping mechanism 4, or it can also be as shown in FIG. Figure 1 In the example shown in FIG. 1 , the mounting base 1 has a built-in clamping base plate for placing the workpiece.

[0035] The clamping device 100 in this embodiment has improved and optimized its structure and driving mode, and can perform clamping operations on two different workpieces at the same time. It is more versatile and has a wider range of applications. It is particularly suitable for clamping operations on special-shaped workpieces. It can effectively reduce the frequency of replacing the clamping device during the production process, which is beneficial to improving production efficiency. It can also reduce the types of clamping devices required for production, which is beneficial to reducing equipment costs.

[0036] In a further embodiment of the present invention, Figure 1 and Figure 2 As shown, the transmission mechanism 5 includes a transmission gear 51. In the second direction, the transmission gear 51 is arranged between the first clamping mechanism 3 and the second clamping mechanism 4, and the transmission mechanism 5 is rotationally connected to the lifting mechanism 2; the transmission gear 51 can perform lifting and lowering motions together with the lifting mechanism 2, and can also rotate relative to the lifting mechanism 2. Correspondingly, the first clamping mechanism 3 is provided with a meshing tooth structure on the side facing the transmission gear 51, and meshes with the transmission gear 51, and the second clamping mechanism 4 is provided with a meshing tooth structure on the side facing the transmission gear 51, and meshes with the transmission gear 51. When the transmission gear 51 is driven by the lifting mechanism 2 to perform lifting and lowering motions in the first direction, it can drive the first clamping mechanism 3 and the second clamping mechanism 4 to perform lifting and lowering motions synchronously, that is, the first clamping mechanism 3 and the second clamping mechanism 4 slide in the same direction; when the transmission gear 51 rotates relative to the lifting mechanism 2, the meshing of the meshing teeth can make one of the first clamping mechanism 3 and the second clamping mechanism 4 move upward, and the other move downward, for example Figure 2 In the example, when the transmission gear 51 rotates clockwise, it drives the first clamping mechanism 3 to move upward, and drives the second clamping mechanism 4 to move downward, that is, the first clamping mechanism 3 and the second clamping mechanism 4 move in opposite directions in the first direction.

[0037] During the compaction operation, Figure 2 In the example, the height of the workpiece 1 61 corresponding to the first clamping mechanism 3 is higher than the height of the workpiece 2 62 corresponding to the second clamping mechanism 4; when the lifting mechanism 2 drives the first clamping mechanism 3 and the second clamping mechanism 4 to descend through the transmission gear 51, the first clamping mechanism 3 first contacts with the workpiece 1 61, and is subjected to the reaction force of the workpiece 1 61, and the first clamping mechanism 3 moves upward relative to the transmission gear 51, and drives the second clamping mechanism 4 to move downward through the transmission gear 51; when the second clamping mechanism 4 contacts with the corresponding workpiece 2 62, it is subjected to the reaction force of the workpiece 2 62, and the second clamping mechanism 4 moves upward relative to the transmission gear 51, and the transmission gear 51 is reversed and drives the first clamping mechanism 3 to move downward. This is repeated many times until the first clamping mechanism 3 contacts and clamps the corresponding workpiece 1 61, and the second clamping mechanism 4 contacts and clamps the corresponding workpiece 2 62, completing the clamping operation of the two workpieces.

[0038] Furthermore, if Figures 1 to 3 As shown, the mounting base 1 includes a mounting vertical plate 12, and a first opening 121 is formed on the mounting vertical plate 12. The first opening 121 penetrates along the third direction and extends along the first direction to form a Figure 2 The third direction is perpendicular to the first direction and the second direction. The transmission gear 51 is located on the side of the mounting plate 12 connected to the first clamping mechanism 3 and the second clamping mechanism 4, and is arranged opposite to the first opening 121. The lifting mechanism 2 is arranged on the side of the mounting plate 12 away from the transmission gear 51, that is, the lifting mechanism 2 and the transmission gear 51 are respectively located on both sides of the mounting plate 12. Figure 3 In the example, the space on both sides of the vertical plate 12 can be fully utilized and arranged reasonably, and the force on the clamping device 100 is relatively more uniform.

[0039] Preferably, if Figure 3 and Figure 4 As shown, the mounting base 1 also includes a clamping bottom plate 11 and a reinforcing plate 14. The clamping bottom plate 11 is horizontally arranged below the mounting vertical plate 12 and is fixedly connected to the mounting vertical plate 12. The clamping bottom plate 11 can be used as a workpiece placement platform. In a production environment, the clamping device 100 can also be fixed to a designated processing position through the clamping bottom plate 11. The reinforcing plate 14 is arranged on the side of the mounting vertical plate 12 away from the transmission gear 51, and the reinforcing plate 14 is fixedly connected to the mounting vertical plate 12 and the clamping bottom plate 11 at the same time to improve the connection strength between the mounting vertical plate 12 and the clamping bottom plate 11; preferably, as Figure 4 In the example in FIG. 1 , the number of reinforcing plates 14 is two, which are symmetrically arranged on both sides of the lifting mechanism 2 in the second direction.

[0040] Furthermore, if Figure 3 and Figure 4 As shown, the transmission mechanism 5 also includes a rotating shaft 52 and an adjusting member 53. The rotating shaft 52 extends along the third direction and is inserted into the first opening 121; one end of the rotating shaft 52 is rotatably connected to the lifting mechanism 2, and the other end of the rotating shaft 52 is fixedly connected to the transmission gear 51. The rotating shaft 52 forms a rotational connection between the transmission gear 51 and the lifting mechanism 2, so as to provide support and transmit power to the transmission gear 51 through the rotating shaft 52; when the lifting mechanism 2 is lifted and lowered, the rotating shaft 52 can drive the transmission gear 51 to rise and fall synchronously, so that the first clamping mechanism 3 and the second clamping mechanism 4 slide in the same direction in the first direction; when the transmission gear 51 rotates, the rotating shaft 52 rotates synchronously, so that the first clamping mechanism 3 and the second clamping mechanism 4 slide in opposite directions in the first direction.

[0041] The rotating shaft 52 is provided with a shoulder structure 521, which is located between the lifting mechanism 2 and the transmission gear 51, and one end of the shoulder structure 521 abuts against the transmission gear 51 to form an axial limit for the transmission gear 51. The adjusting member 53 is sleeved on one end of the rotating shaft 52 away from the transmission gear 51, and the adjusting member 53 abuts against the side of the lifting mechanism 2 away from the transmission gear 51; by operating the adjusting member 53, one end of the rotating shaft 52 can be moved axially so that the lifting mechanism 2 abuts against the end of the shoulder structure 521 away from the transmission gear 51 and forms a locking state.

[0042] In the locked state, a certain tensioning force is applied to the transmission gear 51, and the transmission gear 51 can maintain the current state to a certain extent, that is, the transmission gear 51 is in a non-free state, at which time, the first clamping mechanism 3 and the second clamping mechanism 4 meshing with the transmission gear 51 can maintain a relatively static state. When the lifting mechanism 2 performs lifting movement, the transmission gear 51 can drive the first clamping mechanism 3 and the second clamping mechanism 4 to slide in the same direction, and in the absence of other external forces, the first clamping mechanism 3 and the second clamping mechanism 4 will not slide in the opposite direction, and the transmission gear 51 will not rotate, that is, the first clamping mechanism 3, the second clamping mechanism 4 and the transmission gear 51 maintain a relatively static state. The above arrangement can prevent the first clamping mechanism 3 and the second clamping mechanism 4 from moving freely or generating an impact force on the workpiece under the action of gravity, and at the same time is conducive to improving the efficiency of the lifting movement, and can enable the first clamping mechanism 3 and the second clamping mechanism 4 to quickly descend to a height close to the corresponding workpiece.

[0043] Furthermore, if Figure 3 and Figure 4As shown, the adjusting member 53 specifically includes a locking nut 531, a clamping sheet 532 and a spring 533. An external thread structure is provided at a position on the rotating shaft 52 corresponding to the adjusting member 53, and the locking nut 531 is threadedly connected with the external thread structure of the rotating shaft 52; the clamping sheet 532 is sleeved on the rotating shaft 52, and the clamping sheet 532 abuts against a side of the lifting mechanism 2 away from the transmission gear 51; the spring 533 is sleeved on the rotating shaft 52, and the spring 533 is located between the locking nut 531 and the clamping sheet 532, and one end of the spring 533 abuts against the locking nut 531, and the other end abuts against the clamping sheet 532. By tightening the locking nut 531, the spring 533 is compressed, thereby generating pressure on the pressing sheet 532, so that the pressing sheet 532 presses the lifting mechanism 2, so that the rotating shaft 52 and the transmission gear 51 are in a pressing state, so as to facilitate the lifting movement with the lifting mechanism 2; by loosening the locking nut 531, the rotating shaft 52 and the transmission gear 51 are in a contact pressing state, at which time, the rotating shaft 52 and the transmission gear 51 can rotate relative to the lifting mechanism 2, so that the first pressing mechanism 3 and the second pressing mechanism 4 can slide in the opposite direction. Through the above configuration, the rotating shaft 52 and the transmission gear 51 can be adjusted by tightening or loosening the locking nut 531, so as to adapt to the different movement processes of the first pressing mechanism 3 and the second pressing mechanism 4.

[0044] In a further embodiment of the present invention, Figure 3 and Figure 4 As shown, the lifting mechanism 2 specifically includes a telescopic drive mechanism 21 and a movable part 22. The telescopic drive mechanism 21 is arranged on a side of the mounting vertical plate 12 away from the transmission gear 51, and the telescopic drive mechanism 21 is connected to a position close to the top of the mounting vertical plate 12 to support and fix the telescopic drive mechanism 21; the driving end 211 of the telescopic drive mechanism 21 is arranged along the first direction and can perform telescopic movement along the first direction. The movable part 22 is connected to the driving end 211 of the telescopic drive mechanism 21 and is located at a position corresponding to the first opening 121; a through hole 221 is provided on the movable part 22, and the through hole 221 is passed through along the third direction; the rotating shaft 52 is passed through the through hole 221 of the movable part 22 and forms a rotation connection with the movable part 22. When the driving end 211 of the telescopic driving mechanism 21 extends downward, the movable member 22 is driven to move downward, and the rotating shaft 52 and the transmission gear 51 are driven to move downward synchronously; when the driving end 211 of the telescopic driving mechanism 21 is retracted upward, the movable member 22 is driven to move upward, and the rotating shaft 52 and the transmission gear 51 are driven to move upward synchronously. One end of the movable member 22 away from the transmission gear 51 abuts against the adjusting member 53. When the adjusting member 53 is operated to put the rotating shaft 52 in a non-locking state, the rotating shaft 52 and the transmission gear 51 can rotate relative to the movable member 22.

[0045] The telescopic drive mechanism 21 can be any one of a pneumatic cylinder, an electric cylinder or a hydraulic cylinder; the movable member 22 is preferably as follows Figure 3 In the block structure shown in FIG. 2 , one or more bearings may be provided in the through hole 221 to form a rotational fit with the rotating shaft 52 .

[0046] It should be noted that the above is only a preferred arrangement of the lifting mechanism 2. Other arrangements may be used according to specific assembly requirements. For example, the telescopic drive mechanism 21 is arranged near the bottom of the mounting vertical plate 12, and the driving end 211 of the telescopic drive mechanism 21 is arranged upward, which can also drive the movable member 22 to perform lifting and lowering movements. In addition, the lifting mechanism 2 may also adopt other structural forms, such as the matching of a screw and a nut block, the meshing of a gear rack, etc., which will not be described in detail here.

[0047] In a further embodiment of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the mounting base 1 also includes a first guide rail 131 and a second guide rail 132. The first guide rail 131 and the second guide rail 132 are located on the same side of the transmission gear 51 in the third direction relative to the mounting vertical plate 12, and in the second direction, the first guide rail 131 and the second guide rail 132 are respectively located on both sides of the transmission gear 51; the first guide rail 131 and the second guide rail 132 are both connected to the mounting vertical plate 12, and both extend along the first direction. Correspondingly, the first clamping mechanism 3 includes a first slider 31 and a first rack 32. The first slider 31 is slidably connected to the first guide rail 131 and can slide relative to the first guide rail 131 in the first direction; the first rack 32 is connected to the side of the first slider 31 facing the transmission gear 51, and the side of the first rack 32 facing the transmission gear 51 is provided with a meshing tooth structure, and meshes with the transmission gear 51 through the meshing tooth structure. Similarly, the second slider 41 is slidably connected to the second guide rail 132 and can slide relative to the second guide rail 132 along the first direction; the second rack 42 is connected to the side of the second slider 41 facing the transmission gear 51, and the side of the second rack 42 facing the transmission gear 51 is provided with a meshing tooth structure, and meshes with the transmission gear 51 through the meshing tooth structure. Among them, a first pressing plate 311 is provided at the bottom of the first slider 31, and a second pressing plate 411 is provided at the bottom of the second slider 41. The first pressing plate 311 and the second pressing plate 411 are used to contact and press the corresponding workpiece below.

[0048] In practical applications, the specific dimensions of the first rack 32 and the second rack 42 in the first direction can be set according to the movement strokes of the first slider 31 and the second slider in the first direction. In addition, the first slider 31 can be provided with a structure adapted to the first guide rail 131 to form a sliding connection, for example, a slide groove structure is provided on the side of the first slider toward the first guide; the second slider 41 is similar to the first slider 31, and will not be described in detail here.

[0049] Furthermore, if Figure 5 and Figure 7 As shown, a first contact piece 33 is provided at the bottom of the first pressing plate 311 , and correspondingly, a second contact piece 43 is provided at the bottom of the second pressing plate 411 . The first contact piece 33 and the second contact piece 43 are used to contact the corresponding workpiece.

[0050] In a specific implementation, the bottom surface of the first contact member 33 and the bottom surface of the second contact member 43 are respectively provided with contact structures adapted to different workpieces, for example Figure 6 In the example, the contact structure at the bottom of the first contact member 33 is an arc-shaped structure that is concave upward, suitable for cooperating with a workpiece with an arc surface at the top, and the contact structure at the bottom of the second contact member 43 is a plane structure that is suitable for cooperating with a workpiece with a plane at the top. Of course, depending on the structure of the workpiece, the contact structure can also adopt other structural forms, such as spherical structure, triangular structure, trapezoidal structure, etc.

[0051] In another specific implementation, the first contact member 33 and the second contact member 43 can adopt a flexible structure, such as a buffer block made of rubber, foam or other materials. When in contact with the workpiece, the flexible structure can undergo a certain deformation to adapt to the top of the workpiece, and can also play a buffering role to prevent damage to the workpiece surface during contact.

[0052] It should be noted that, according to specific processing requirements, the above two methods can also be used in combination, that is, the first contact member 33 and the second contact member 43 both adopt a flexible structure, and a contact structure adapted to the shape of different workpieces is also provided on the bottom surface.

[0053] Furthermore, if Figure 5 and Figure 6As shown, a first limit block 34 is provided above the first guide rail 131, the first limit block 34 corresponds to the first slider 31, and is fixedly connected to the mounting vertical plate 12; the first limit block 34 is used to limit the first slider 31, and when the first slider 31 rises to the top and contacts the first limit block 34, the first slider 31 rises to the limit position. Similarly, a second limit block 44 is provided above the second guide rail 132, the second limit block 44 corresponds to the second slider 41, and is fixedly connected to the mounting vertical plate 12; the second limit block 44 is used to limit the second slider 41, and when the second slider 41 rises to the top and contacts the second limit block 44, the second slider 41 rises to the limit position. Among them, since the first clamping mechanism 3 and the second clamping mechanism 4 are both engaged with the transmission gear 51, one of the first slider 31 and the second slider 41 rises relative to the transmission gear 51, and the other falls relative to the transmission gear 51. Therefore, when the lifting mechanism 2 is in a stationary state, the first limit block 34 limits the rising limit position of the first slider 31 and also limits the falling limit position of the second slider 41. At this time, the first slider 31 stops rising and the second slider 41 also stops falling; correspondingly, the second limit block 44 limits the rising limit position of the second slider 41 and also limits the falling limit position of the first slider 31. At this time, the second slider 41 stops rising and the first slider 31 stops falling. Preferably, a buffer structure can be set at the bottom of the first limit block 34 and the second limit block 44 to play a buffering role when contacting with the first slider 31 and the second slider 41.

[0054] In this embodiment, through the cooperation of the first limit block 34, the second limit block 44 and the first clamping mechanism 3, the second clamping mechanism 4 and the transmission gear 51, the first slider 31 and the second slider 41 can be limited to each other to cooperate with the clamping operation of the first pressure plate 311 and the second pressure plate 411.

[0055] In a further embodiment of the present invention, the clamping device 100 further includes a controller. The controller is connected to the lifting mechanism 2 in the same direction. When in use, the controller can receive an operation signal from the loading and unloading mechanism and control the lifting mechanism 2 to perform a corresponding lifting movement, thereby performing a clamping operation on the corresponding workpiece to achieve automatic control.

[0056] It can be understood that during the production process, various specifications and parameters of the workpiece to be operated are stored in the corresponding control system. When the loading and unloading mechanism is loading, the specifications and parameters of the corresponding workpiece can be transmitted to the controller of the clamping device 100, and the controller can perform corresponding control operations according to the specifications and parameters of the workpiece to be operated; when the workpiece changes, the controller can also promptly know the specifications and parameters of the changed workpiece and adjust the control operation accordingly.

[0057] An example of a specific pressing operation process of the pressing device 100 of the present invention is provided below.

[0058] like Figure 6 As shown, in the initial state, the driving end 211 of the telescopic driving mechanism 21 is in a retracted state, and the first slider 31 and the second slider 41 are in the upper limit position. At this time, loading is performed, and the two workpieces are placed at corresponding positions on the pressing bottom plate 11, wherein the height of the workpiece 1 61 corresponding to the first pressing plate 311 is greater than the height of the workpiece 2 62 corresponding to the second pressing plate 411, and both workpieces are special-shaped parts, such as Figure 6 In the example, the top surface of the workpiece 1 61 on the left is an arc surface, and the top surface of the workpiece 2 62 on the right is a trapezoidal surface. The first contact member 33 and the second contact member 43 are both flexible structures, and the bottoms are respectively provided with contact structures adapted to the corresponding workpieces.

[0059] Afterwards, if Figure 7 As shown, the telescopic drive mechanism 21 starts to work, the drive end 211 extends downward, and the transmission gear 51 drives the first clamping mechanism 3 and the second clamping mechanism 4 to slide downward together. When the first contact member 33 of the first clamping mechanism 3 contacts the corresponding workpiece 1 61 below, the second contact member 43 has not yet contacted the corresponding workpiece 2 62 below. Figure 8 As shown, the driving end 211 of the telescopic driving mechanism 21 continues to extend downward, and the first contact member 33 and the first pressure plate 311 are subjected to the reaction force of the workpiece 1 61 below, so that the first slider 31 slides upward to a certain height, and at the same time, the transmission gear 51 is driven to rotate clockwise through the first rack 32; at the same time, the second clamping mechanism 4 slides downward under the drive of the lifting mechanism 2, and at the same time, the second slider 41 further slides downward under the drive of the transmission gear 51 and the second rack 42 until the second contact member 43 contacts the corresponding workpiece 2 62 below. Thereafter, the driving end 211 of the telescopic driving mechanism 21 continues to extend downward, so that the second contact member 43 and the second pressure plate 411 are subjected to the reaction force of the corresponding workpiece 2 62 below, and the second slider 41 slides upward to a certain height, and at the same time, the transmission gear 51 is driven to rotate counterclockwise through the second rack 42, and the first slider 31, the first pressure plate 311 and the first contact member 33 are driven to slide downward through the first rack 32. This is repeated many times until the state as shown in the figure is reached. Fig. 9 In the state shown, the first contact member 33 contacts and presses the corresponding workpiece 1 61 below, and the second contact member 43 contacts and presses the corresponding workpiece 2 62 below, reaching a balanced state, and completing the pressing operation.

[0060] It should be noted that when the height of the workpiece 2 62 corresponding to the second clamping mechanism 4 is greater than the height of the workpiece 1 61 corresponding to the first clamping mechanism 3, the principle of the clamping operation is similar to the above case, with only the order of individual steps being different, which will not be repeated here.
