Description

Technical Field

[0001] The present invention relates to the technical field of material loading, and in particular to a material transfer auxiliary device. Background Art

[0002] For example, the publication number "CN220518354U" discloses "a safe-to-use lifting trolley", which includes a device body, a lifting mechanism and a limiting mechanism. The device body includes a vehicle body; the lower end of the vehicle body is movably connected to a moving wheel; the front end of the vehicle body is movably connected to a handlebar; a lifting mechanism is installed inside the device body; the lifting mechanism includes a reciprocating motor and a storage rack; the interior of the vehicle body is fixedly connected to a reciprocating motor; one end of the reciprocating motor is transmission-connected to a first conical tooth; the outer surface of the first conical tooth is transmission-connected to a second conical tooth; one end of the second conical tooth is fixedly connected to a connecting column. However, in actual applications, this type of lifting trolley can only perform lifting operations. After lifting to a certain height, the workpiece still needs to be manually transported to the processing machine tool. Since there is a certain height between the processing platform of the machine tool and the ground, there are risks in transportation. Moreover, due to the obstruction of the machine tool, it is difficult to exert force, and generally multiple people are required to carry it together. Summary of the Invention

[0003] In response to the problem mentioned in the background technology that the existing technology still needs to be transported at a high position and will be interfered with by the machine tool, the present invention provides a material moving auxiliary device, which can improve the realization of only one transport at a low position. The auxiliary device can directly transfer the workpiece to the machine tool for processing, avoiding the influence of the machine tool itself on the transport, while ensuring the safety of the transport and reducing the number of transports.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions.

[0005] A material moving auxiliary device includes a lifting component, a base unit is provided on the lifting component, a first sliding platform is slidably connected to the base unit, a second sliding platform is slidably connected to the first sliding platform, the sliding directions of the first sliding platform and the second sliding platform are staggered, a workpiece can be placed on the second sliding platform, the first sliding platform and the base unit can be staggered in the relative sliding direction, and the second sliding platform and the first sliding platform can be staggered in the relative sliding direction. The lifting trolley in the existing technology can generally only lift the plane supporting the workpiece through the lifting unit, and the lifting trolley can only stay at the side of the machine tool, and cannot transfer the workpiece to the machine tool. The operation of transferring the workpiece to the machine tool still requires the assistance of staff to achieve the horizontal movement of the workpiece. Since the lifting trolley stays at the side of the machine tool, the staff will be interfered with by the lifting trolley and the volume occupied by the machine tool itself when moving the workpiece, and cannot lift and move it horizontally well. Generally, multiple people are required to work together, which reduces production efficiency. In addition, since the lifting trolley has lifted the workpiece to a higher height, generally about one meter, and due to the heavy weight of the workpiece, there will be greater safety risks during the horizontal movement.

[0006] Therefore, in order to solve the above problems, the present application adopts the method of setting up multiple sliding platforms. The sliding platforms include a first sliding platform and a second sliding platform, wherein the first sliding platform is slidably connected to the base unit, and the base unit is connected to the lifting assembly and can be driven to rise by the lifting assembly. The base unit can synchronously drive the first sliding platform to rise, and the second sliding platform connected to the first sliding platform is also synchronously lifted, wherein the workpiece is placed on the second sliding platform, and in the present application, the sliding directions of the first sliding platform and the second sliding platform are set to be staggered. Generally, in actual applications, the sliding directions of the first sliding platform and the second sliding platform are set to be perpendicular to each other, so as to facilitate the workpiece alignment and movement; the first sliding platform can be offset from the base unit, so that the first sliding platform can be separated from the base unit along the sliding direction, so that the base unit can be transferred to the upper space of the machine tool when it is on the side of the machine tool, and the second sliding platform can be offset from the first sliding platform, so that the workpiece can move on the machine tool and be connected to the fixed parts on the machine tool. Since the second sliding unit can be offset relative to the first sliding unit, the workpiece is also offset relative to the first sliding unit. Then, the workpiece can be separated from the entire auxiliary device through the reverse movement of the second sliding unit, and then the first sliding unit is reset to complete the entire workpiece loading process. In this process, the staff only needs to move the workpiece when the base unit is in a lower position, and at this time the base unit is not near the machine tool, so that there will not be many interference factors, and due to the low handling height, the safety risk is lower. Since the first sliding platform and the second sliding platform are offset by a distance compared to the base unit, a counterweight unit is provided on the base unit so that when the first sliding platform and the second sliding platform slide out of alignment, the counterweight unit can be supported against the overturning force brought by the workpiece.

[0007] Preferably, the base unit is provided with a fixed slide rail, the first sliding platform is provided with a movable slide rail, a transition slide rail is slidably connected between the fixed slide rail and the movable slide rail, and the fixed slide rail and the movable slide rail are slidably connected on both sides of the transition slide rail. A fixed slide rail is provided on the base unit, and a movable slide rail is provided on the first sliding platform. In order to achieve the staggered setting of the first sliding platform and the base unit, a transition slide rail is connected between the movable slide rail and the fixed slide rail, and the transition slide rail can be slidably connected to the fixed slide rail and the movable slide rail respectively, thereby ensuring that the first sliding platform can extend out of the base unit to the maximum extent. At the same time, the connection stability between the first sliding platform and the base unit is ensured by the transition slide rail. When the first sliding platform slides to the maximum extent, the transition slide rail can still ensure a large connection area with the movable slide rail and the fixed slide rail. If the setting of the transition slide rail is cancelled, when the first sliding platform slides to the maximum extent, the connection area between the fixed slide rail and the movable slide rail will become very limited, which will affect the stability of the connection.

[0008] Preferably, guide grooves are provided on both sides of the transition rail, and the guide grooves on both sides are staggered in the sliding direction, and positioning blocks capable of slidingly connecting to the guide grooves are provided on the fixed rail and the movable rail. Guide grooves are provided on both sides of the transition rail, and the guide grooves are in the shape of long strip groove structures, extending in the same direction as the sliding direction, and provided on both sides of the transition rail. The guide grooves are also staggered, for example, after the first sliding platform slides a certain distance relative to the base unit, the guide groove on the side connected to the fixed rail is provided close to the fixed rail, while the guide groove on the side connected to the movable rail is provided close to the movable rail. Positioning blocks are provided on the corresponding fixed rail and movable rail, wherein the positioning blocks are slidably connected to the guide grooves, thereby ensuring the relative stability between the transition rail, the movable rail, and the fixed rail.

[0009] Preferably, guide wheel groups are provided on both sides of the transition slide, and the guide wheel groups on both sides respectively abut the corresponding fixed slide and movable slide. The guide wheel groups provided on both sides of the transition slide can be slidably connected with the fixed slide and the movable slide, and the guide wheels inside the guide wheel group abut the fixed slide and the movable slide, so that the relative sliding of the pillow can be smooth and avoid sticking, especially when a workpiece is placed on the second sliding platform, the friction is reduced to avoid the occurrence of excessive sliding resistance. The guide wheel groups on both sides are also staggered, and the guide wheel groups are not provided at all positions on one side. The setting area is roughly consistent with the setting area of ​​the guide groove. The guide wheel group can cover the relative position path of the fixed slide-transition slide and the movable slide-transition slide, thereby saving costs and avoiding interference between the guide wheel groups on both sides during installation.

[0010] Preferably, the first sliding platform is provided with a guide rail extending in the sliding direction of the second sliding platform, and the second sliding platform is provided with a guide groove slidably connected to the guide rail. The guide rail provided on the first sliding platform is slidably connected to the guide groove on the second sliding platform to ensure the sliding stability of the second sliding platform relative to the first sliding platform; the guide rail and the guide groove can be interchanged, that is, the guide groove is provided on the first sliding platform and the guide rail is provided on the second sliding platform. This arrangement can reduce the risk of interference during the return process in the adjustment block and fixed block scheme described below.

[0011] Preferably, the second sliding platform is provided with a placement groove adapted to the shape of the workpiece, and a baffle capable of abutting the workpiece is provided at the end of the placement groove. The placement groove is provided on the second sliding platform, and its shape is adapted to the shape of the workpiece, thereby ensuring the stability of the workpiece placed on the second sliding platform. The baffle is provided at the end of the placement groove, which can drive the workpiece to move, thereby avoiding relying solely on friction to drive movement and ensuring stability.

[0012] Preferably, a fixed block is provided on the second sliding platform, an adjusting block is movably connected to the fixed block, an adjusting rod is connected to the adjusting block, the adjusting rod is slidably connected to the fixed block, a plurality of flat grooves are provided on the adjusting rod, the adjusting rod passes through the fixed block, and the adjusting rod is respectively connected to limit buckles on both sides of the fixed block that can engage with the flat grooves. The cam is fixedly mounted on the support frame, and the adjusting block is fixedly connected to the support frame, and the adjusting block is slidably connected to the fixed block, that is, the fixed block remains in a fixed state relative to the adjusting block, and the adjusting block can realize axial movement relative to the fixed block through the adjusting rod. In the process of pushing the workpiece to be connected to the machine tool, the size of the workpiece is adapted by increasing the relative distance between the adjusting block and the fixed block, thereby ensuring the uniformity and stability of the workpiece support. After the workpiece is connected to the machine tool, the second sliding platform is pulled out, and the relative gap between the locking pin adjusting block and the fixed block is simultaneously locked to avoid interference between the adjusting block and the bottom of the workpiece during the process of returning the first sliding platform. The above structure can ensure the uniformity of the workpiece support while also achieving smoothness in the return process and avoiding interference with the workpiece. Furthermore, a flat groove is provided on the adjusting rod, and a plurality of flat grooves are provided. The flat grooves can be engaged with the limit buckles, and the flat grooves are connected by the limit buckles, which can respectively abut the fixed blocks on both sides, thereby achieving the limiting effect in the stretching and pushing directions. The setting gap of the flat grooves needs to be satisfied. When the limit buckles on both sides of the fixed block are connected to the flat grooves, they can abut the fixed block to ensure that the position of the adjusting block is fixed relative to the fixed block.

[0013] Preferably, a telescopic limiting unit is provided on a side of the adjusting block away from the fixed block, a limiting plane is provided on a side of the telescopic limiting unit close to the fixed block, and an adaptive elastic unit is provided between the telescopic limiting unit and the adjusting block. The cam is adapted to move the adjusting block toward the workpiece, whereby the adjusting block is moved downwards to allow the adjusting block to move in a direction parallel to the workpiece, and the cam is adapted to move the adjusting block toward the workpiece, whereby the adjusting block is moved downwards to allow the adjusting block to move in a direction parallel to the workpiece, and the cam is adapted to move the adjusting block toward the workpiece. And through the above setting, it will not affect the normal loading and placing process of the workpiece. When the workpiece is placed on the second sliding platform, the telescopic limit unit can be squeezed so that the entire adjustment block is used for support, and the baffle on the fixed block is used to push the workpiece to move.

[0014] Preferably, the first sliding platform and the second sliding platform are provided with push-pull handles, which facilitate the staff to drive the first sliding platform and the second sliding platform.

[0015] Preferably, the base unit is provided with positioning plates at both ends along the sliding direction of the first sliding platform, the positioning plates are provided with positioning grooves, the upper end of the first sliding platform is connected with an elastic limiting column, the base unit includes a main body plate, the side of the positioning plate provided with the positioning groove is higher than the upper surface of the main body plate, and the elastic limiting column can be engaged with the positioning groove. A positioning plate is provided on the base unit, the height of the positioning plate is higher than the upper surface of the main body plate, and the end of the first sliding platform is connected with an elastic limiting column. The movement of the first sliding platform will drive the movement of the elastic limiting column. Since the horizontal height of the main body plate is determined, the elastic limiting column will not interfere with the main body plate. When the movement is fast to the extreme position, the elastic limiting column will interfere with the positioning plate and engage with the positioning groove at the extreme position, thereby providing feedback to the staff.

[0016] The beneficial effects of the present invention are as follows: (1) It can improve the ability to achieve only one handling at a low position, and the workpiece can be directly transferred to the machine tool for processing through auxiliary devices, avoiding the influence of the machine tool itself on the handling, while ensuring the safety of the handling and reducing the number of handling times; (2) It is possible to ensure the connection stability between the first sliding unit and the base unit, while ensuring the maximum distance that the first sliding unit can extend relative to the base unit; (3) By adjusting the movement of the block, while ensuring the uniformity and stability of the support for various workpieces, interference with the workpiece during the recovery process can be avoided, making the recovery effect smoother; (4) It can improve the disassembly efficiency of workpieces of different specifications without affecting the loading function of the workpieces.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: like Figure 1 、 2As shown, a material moving auxiliary device includes a lifting component 1, a base unit 2 is provided on the lifting component 1, a first sliding platform 3 is slidably connected to the base unit 2, a second sliding platform 4 is slidably connected to the first sliding platform 3, the sliding directions of the first sliding platform 3 and the second sliding platform 4 are staggered, a workpiece 7 can be placed on the second sliding platform 4, the first sliding platform 3 and the base unit 2 can form an offset arrangement in the relative sliding direction, and the second sliding platform 4 and the first sliding platform 3 can form an offset arrangement in the relative sliding direction. The lifting trolley in the prior art can generally only lift the plane supporting the workpiece 7 through the lifting unit, and the lifting trolley can only stay at the side of the machine tool, and cannot transfer the workpiece 7 to the machine tool. The operation of transferring the workpiece 7 to the machine tool still requires the assistance of staff to achieve the translation of the workpiece 7. Since the lifting trolley stays at the side of the machine tool, the staff will be interfered with by the lifting trolley and the volume occupied by the machine tool itself when transporting the workpiece 7, and cannot lift and move it horizontally well. Generally, multiple people are required to work together, which reduces production efficiency. In addition, since the lifting trolley has lifted the workpiece 7 to a higher height, generally about one meter, and since the workpiece 7 is heavy, there will be greater safety risks during the process of transporting and moving it horizontally.

[0025] Therefore, in order to solve the above problems, the present application adopts the method of setting up multiple sliding platforms to solve the problem. The sliding platforms include a first sliding platform 3 and a second sliding platform 4, wherein the first sliding platform 3 is slidably connected to the base unit 2, and the base unit 2 is connected to the lifting component 1 and can be driven to rise by the lifting component 1. The base unit 2 can synchronously drive the first sliding platform 3 to rise, and the second sliding platform 4 connected to the first sliding platform 3 is also synchronously lifted, wherein the workpiece 7 is placed on the second sliding platform 4, and in the present application, the sliding directions of the first sliding platform 3 and the second sliding platform 4 are set to be staggered. Generally, in actual applications, the sliding directions of the first sliding platform 3 and the second sliding platform 4 are set to be perpendicular to each other, so as to facilitate Alignment and movement of the workpiece 7; the first sliding platform 3 can be offset from the base unit 2, so that the first sliding platform 3 can be separated from the base unit 2 along the sliding direction, so that the base unit 2 can transfer the workpiece 7 to the upper space of the machine tool when it is on the side of the machine tool, and the second sliding platform 4 can be offset from the first sliding platform 3, so that the workpiece 7 can move on the machine tool and connect with the fixed parts on the machine tool. Since the second sliding unit can be offset relative to the first sliding unit, the workpiece 7 is also offset relative to the first sliding unit. Then, the workpiece 7 can be separated from the entire auxiliary device through the reverse movement of the second sliding unit, and then the first sliding unit is reset to complete the entire loading process of the workpiece 7. During this process, the staff only needs to move the workpiece 7 when the base unit 2 is in a lower position, and at this time the base unit 2 is not near the machine tool, so that there will not be many interference factors, and due to the low handling height, the safety risk is lower. Since the first sliding platform 3 and the second sliding platform 4 are offset by a certain distance compared to the base unit 2, a counterweight unit is provided on the base unit 2 so that when the first sliding platform 3 and the second sliding platform 4 slide out of alignment, the counterweight unit can be supported to resist the overturning force brought by the workpiece 7.

[0026] like Figure 2 、 3As shown, a fixed slide rail 21 is provided on the base unit 2, a movable slide rail 31 is provided on the first sliding platform 3, a transition slide rail 5 is slidably connected between the fixed slide rail 21 and the movable slide rail 31, and the fixed slide rail 21 and the movable slide rail 31 are respectively slidably connected on both sides of the transition slide rail 5. A fixed slide rail 21 is arranged on the base unit 2, and a movable slide rail 31 is arranged on the first sliding platform 3. In order to realize the staggered setting of the first sliding platform 3 and the base unit 2, a transition slide rail 5 is connected between the movable slide rail 31 and the fixed slide rail 21. The transition slide rail 5 can slide and connect the fixed slide rail 21 and the movable slide rail 31 respectively, thereby ensuring that the first sliding platform 3 can extend out of the base unit 2 to the maximum extent. At the same time, the connection stability between the first sliding platform 3 and the base unit 2 is ensured by the transition slide rail 5. When the first sliding platform 3 slides to the maximum extent, the transition slide rail 5 can still ensure a large connection area between the movable slide rail 31 and the fixed slide rail 21. If the setting of the transition slide rail 5 is cancelled, when the first sliding platform 3 slides to the maximum extent, the connection area between the fixed slide rail 21 and the movable slide rail 31 will become very limited, which will affect the stability of the connection.

[0027] like Figure 2 、 3 As shown, guide grooves 51 are provided on both sides of the transition rail 5. The guide grooves 51 on both sides are staggered in the sliding direction. Positioning blocks 52 that can be slidably connected to the guide grooves 51 are provided on the fixed rail 21 and the movable rail 31. Guide grooves 51 are provided on both sides of the transition rail 5. The guide grooves 51 are in the shape of long strips, extending in the same direction as the sliding direction. The guide grooves 51 are provided on both sides of the transition rail 5, and the guide grooves 51 on both sides are also staggered. For example, after the first sliding platform 3 slides a distance relative to the base unit 2, the guide groove 51 on the side connected to the fixed rail 21 is arranged close to the fixed rail 21, while the guide groove 51 on the side connected to the movable rail 31 is arranged close to the movable rail 31. Positioning blocks 52 are provided on the corresponding fixed rail 21 and the movable rail 31, wherein the positioning blocks 52 are slidably connected to the guide grooves 51, thereby ensuring the relative stability between the transition rail 5, the movable rail 31, and the fixed rail 21.

[0028] like Figure 2 、 3As shown, guide wheel groups 53 are respectively provided on both sides of the transition slide 5, and the guide wheel groups 53 on both sides respectively abut the corresponding fixed slide 21 and movable slide 31. The guide wheel groups 53 provided on both sides of the transition slide 5 can be slidably connected with the fixed slide 21 and the movable slide 31. The guide wheels inside the guide wheel group 53 abut the fixed slide 21 and the movable slide 31, thereby ensuring the smoothness of the relative sliding of the pillow and avoiding jamming. In particular, when a workpiece 7 is placed on the second sliding platform 4, friction is reduced to avoid excessive sliding resistance. The guide wheel groups 53 on both sides are also staggered. The guide wheel groups 53 are not provided at all positions on one side. The setting area is substantially consistent with the setting area of ​​the guide groove 51. The guide wheel groups 53 can cover the relative position path of the fixed slide 21-transition slide 5 and the movable slide 31-transition slide 5, thereby saving costs. However, interference between the guide wheel groups 53 on both sides during installation is not avoided.

[0029] like Figure 2 As shown, the first sliding platform 3 is provided with a guide rail 32 extending along the sliding direction of the second sliding platform 4, and the second sliding platform 4 is provided with a guide groove 41 slidably connected to the guide rail 32. The guide rail 32 is provided on the first sliding platform 3 and is slidably connected to the guide groove 41 on the second sliding platform 4, ensuring the sliding stability of the second sliding platform 4 relative to the first sliding platform 3. The guide rail 32 and the guide groove 41 can be replaced with each other, that is, the guide groove 41 is provided on the first sliding platform 3, and the guide rail 32 is provided on the second sliding platform 4. Through this arrangement, the risk of interference during the recovery process can be reduced in the solution of the adjustment block 45 and the fixed block 44 described below.

[0030] like Figure 2 As shown, the second sliding platform 4 is provided with a placement groove 42 adapted to the shape of the workpiece 7, and a baffle 43 capable of abutting the workpiece 7 is provided at the end of the placement groove 42. The placement groove 42 is provided on the second sliding platform 4, and the shape of the placement groove 42 is adapted to the shape of the workpiece 7, thereby ensuring the stability of the workpiece 7 placed on the second sliding platform 4. The baffle 43 is provided at the end of the placement groove 42, which can drive the workpiece 7 to move, thereby avoiding relying solely on friction to drive movement and ensuring stability.

[0031] like Figure 2 As shown, a push-pull handle 6 is provided on the first sliding platform 3 and the second sliding platform 4. The push-pull handle 6 facilitates the staff to drive the first sliding platform 3 and the second sliding platform 4.

[0032] Example 2: like Figure 4As shown, a fixed block 44 is provided on the second sliding platform 4, and an adjusting block 45 is movably connected to the fixed block 44. An adjusting rod 46 is connected to the adjusting block 45. The adjusting rod 46 is slidably connected to the fixed block 44, and a plurality of flat grooves 47 are provided on the adjusting rod 46. The adjusting rod 46 passes through the fixed block 44, and the adjusting rod 46 is connected to limit buckles 48 on both sides of the fixed block 44 that can engage with the flat grooves 47. A fixed block 44 and an adjusting block 45 are provided on the second sliding platform 4, wherein the relative distance between the adjusting block 45 and the fixed block 44 can be adjusted by an adjusting rod 46, wherein the adjusting rod 46 is fixedly connected to the adjusting block 45, and the adjusting rod 46 is slidably connected to the fixed block 44, that is, the fixed block 44 remains fixed relative to the adjusting block 45, and the adjusting block 45 can realize axial movement relative to the fixed block 44 through the adjusting rod 46, so that in the process of pushing the workpiece 7 to be connected to the machine tool, the size of the workpiece 7 is adapted to the size of the workpiece 7 by increasing the relative distance between the adjusting block 45 and the fixed block 44, thereby ensuring the uniformity and stability of the support for the workpiece 7. After the connection between the workpiece 7 and the machine tool is completed, the second sliding platform 4 is withdrawn and the relative gap between the locking pin adjusting block 45 and the fixed block 44 is locked to avoid interference between the adjusting block 45 and the bottom of the workpiece 7 during the process of returning the first sliding platform 3. Through the above structure, on the basis of ensuring the uniformity of support for the workpiece 7, the smoothness of the return process can also be achieved to avoid interference with the workpiece 7. Furthermore, a flat groove 47 is provided on the adjusting rod 46, and a plurality of flat grooves 47 are provided. The flat groove 47 can be engaged with the limit buckle 48, and the flat groove 47 is connected by the limit buckle 48, which can respectively abut the fixed blocks 44 on both sides, thereby achieving the limiting effect in the stretching and pushing directions. The setting gap of the flat groove 47 needs to be satisfied. When the limit buckles 48 on both sides of the fixed block 44 are connected to the flat groove 47, they can abut the fixed block 44 to ensure that the position of the adjusting block 45 is fixed relative to the fixed block 44.

[0033] In addition to the above-described structure, this embodiment also includes a lifting assembly 1. The lifting assembly 1 is provided with a base unit 2. A first sliding platform 3 is slidably connected to the base unit 2. A second sliding platform 4 is slidably connected to the first sliding platform 3. The sliding directions of the first and second sliding platforms 3 and 4 are staggered. A workpiece 7 can be placed on the second sliding platform 4. The first and second sliding platforms 3 and 4 can be offset relative to the base unit 2 in the sliding direction. The second and second sliding platforms 4 can be offset relative to the first sliding platform 3 in the sliding direction. A fixed rail 21 is provided on the base unit 2. A movable rail 31 is provided on the first sliding platform 3. A transition rail 5 is slidably connected between the fixed rail 21 and the movable rail 31. The fixed rail 21 and the movable rail 31 are respectively slidably connected to either side of the transition rail 5. Guide grooves 51 are provided on either side of the transition rail 5. The guide grooves 51 on either side are staggered relative to the sliding direction. Positioning blocks 52 are provided on the fixed rail 21 and the movable rail 31, respectively, to slidably connect to the guide grooves 51. Guide wheel assemblies 53 are provided on both sides of the transition rail 5, and the guide wheel assemblies 53 on both sides respectively abut the corresponding fixed rail 21 and movable rail 31. The first sliding platform 3 is provided with a guide rail 32 extending along the sliding direction of the second sliding platform 4. The second sliding platform 4 is provided with a guide groove 41 that slidably connects to the guide rail 32. The second sliding platform 4 is provided with a placement groove 42 that adapts to the shape of the workpiece 7. The end of the placement groove 42 is provided with a baffle 43 that can abut the workpiece 7. Push and pull handles 6 are provided on the first sliding platform 3 and the second sliding platform 4.

[0034] Example 3: like Figure 5As shown, a telescopic limit unit 451 is provided on the side of the adjustment block 45 away from the fixed block 44, a limit plane 453 is provided on the side of the telescopic limit unit 451 close to the fixed block 44, and an adaptive elastic unit 454 is provided between the telescopic limit unit 451 and the adjustment block 45. A telescopic limit unit 451 is provided on the adjustment block 45, wherein a compression inclined surface 452 and a limit plane 453 are provided on the telescopic limit unit 451, wherein the compression inclined surface 452 is provided on the side away from the fixed block 44, and the limit plane 453 is provided on the side close to the fixed block 44, wherein the telescopic limit unit 451 can be raised and lowered relative to the adjustment block 45 by the adaptive elastic unit 454, that is, during use, when the workpiece 7 is processed and fixed on the machine tool, the first sliding platform 3 and the second sliding platform 4 can be pulled out, and the adjustment block 45 can be pushed to the other end of the workpiece 7 from under the workpiece 7. During the movement process, due to the presence of the compression slope 452, when the compression slope 452 contacts the workpiece 7, it squeezes the adaptive elastic unit 454, causing the telescopic limit unit 451 to descend, ensuring that the adjustment block 45 can move along the bottom of the workpiece 7. When the limit plane 453 is flush with the end surface of the workpiece 7, the telescopic limit unit 451 pops out, and the limit plane 453 abuts the end surface of the workpiece 7. Since the telescopic limit unit 451 is located on the side of the adjustment block 45 away from the fixed block 44, a local area of ​​the adjustment block 45 still contacts the workpiece 7 for support. At this time, the second sliding unit can be pulled to remove the workpiece 7. This arrangement does not affect the normal loading and placement of the workpiece 7. When the workpiece 7 is placed on the second sliding platform 4, it can squeeze the telescopic limit unit 451, so that the entire adjustment block 45 is used for support, and the baffle 43 on the fixed block 44 is used to push the workpiece 7 to move. The telescopic limit unit 451 is loosely fitted in the adjustment block 45 , and a slot for installing the telescopic limit unit 451 is provided in the adjustment block 45 , in which an adaptive elastic unit 454 is provided.
