Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a clamping device for robot welding. Background Art

[0002] With the improvement of coal mining level and the rapid development of related engineering machinery, hydraulic supports play an important role in mechanized mining production. Among them, the shield beam is an important structural component of the hydraulic support. Affected by the actual working conditions, the length and width of the shield beams of different hydraulic supports vary greatly. At present, the current welding positioner can only perform simple clamping, and cannot accurately adapt to shield beams of different sizes, and cannot meet the requirements of welding and use of shield beams of multiple varieties and small batches. That is, the current welding positioner cannot adapt to workpieces of different sizes, and often requires different models of welding positioners to clamp shield beams with large differences in size.

[0003] Therefore, how to propose a clamping device for robot welding to clamp workpieces with large size differences, thereby improving the application range of the clamping device has become a problem that needs to be solved urgently. Utility Model Content

[0004] The present application proposes a clamping device for robot welding, which solves the problem in the related art that the welding positioner cannot clamp workpieces of different sizes.

[0005] To this end, the first object of the utility model is to provide a clamping device for robot welding.

[0006] In view of this, the technical solution of the first aspect of the utility model provides a clamping device for robot welding, comprising: a chassis assembly; a plurality of clamp assemblies, the plurality of clamp assemblies are arranged at intervals along a first direction, the clamp assemblies include: a sliding beam, slidably mounted on the chassis assembly along the first direction; two clamping components, slidably arranged on both sides of the sliding beam along a second direction, the clamping components are used to clamp the workpiece; wherein the first direction is perpendicular to the second direction, and the plurality of clamp assemblies form one or more clamping spaces for accommodating the workpiece.

[0007] According to the clamping device for robot welding proposed in the present application, it includes a chassis assembly and a plurality of clamping assemblies, and the plurality of clamping assemblies are arranged at intervals along a first direction. The clamping assembly includes a sliding beam and two clamping parts, the sliding beam is slidably mounted on the chassis assembly along the first direction, and the two clamping parts are slidably arranged on both sides of the sliding beam along the second direction, the first direction is perpendicular to the second direction, and the plurality of clamping assemblies form one or more clamping spaces, and the clamping spaces are used to accommodate the workpieces. That is, along the first direction, the plurality of clamping assemblies are arranged at intervals and slidably mounted on the chassis assembly, and the positions of the plurality of clamping assemblies are adjusted to adapt to the length of the workpiece, and the positions of the two clamping parts on the sliding beam are adjusted to adapt to the width of the workpiece. That is, by adjusting the positions of the plurality of clamping assemblies and the positions of the two clamping parts on the sliding beam, the size of the clamping space is adjusted to clamp workpieces of different sizes, especially for some workpieces with large size differences, the clamping device proposed in the present application can also complete the clamping of such workpieces, and realize the precise adaptation of workpieces of different sizes and different weights.

[0008] It is understandable that when the length of the workpiece is relatively long, multiple clamp assemblies form one clamping space, for example, if the workpiece is a shielding beam and the length of the shielding beam workpiece is greater than or equal to 2500mm, the clamping device can only form one clamping space, which greatly increases the upper limit of the size of the clamping space to accommodate larger workpieces. When the length of the workpiece is relatively short, multiple clamp assemblies form multiple clamping spaces, for example, if the workpiece is a shielding beam and the length of the shielding beam workpiece is less than or equal to 2300mm, the clamping device can form two clamping spaces at the same time, and both clamping spaces can accommodate the shielding beam workpiece. The clamping device clamps two shielding beam workpieces at the same time, and the welding robot can weld two shielding beam workpieces at the same time, thereby greatly improving the welding efficiency of the shielding beam workpiece.

[0009] In some technical schemes, optionally, the clamping component includes: a base, slidably mounted on a sliding beam; an adjusting clamp, slidably disposed on the base; a slideway, disposed on the base, and the adjusting clamp is slidably disposed on the base through the slideway; wherein a clamping mechanism is disposed on the adjusting clamp, and the adjusting clamp is clamped or loosened by adjusting the clamping mechanism.

[0010] In this technical solution, the clamping component includes a base, an adjustment fixture and a slideway. The base is mounted on the sliding beam, and the base can slide relative to the sliding beam, so as to adjust the distance between the two clamping components to meet the clamping requirements of shielding beam workpieces of different sizes. The adjustment fixture is slidably arranged on the base, the slideway is arranged on the base, and the adjustment fixture is slidably arranged on the base through the slideway, that is, the adjustment fixture is arranged on the slideway, the slideway is arranged on the base, and the adjustment fixture can slide back and forth on the slideway, so as to achieve high-precision clamping of the workpiece by sliding the adjustment fixture. In addition, a clamping mechanism is also arranged on the adjustment fixture, and the adjustment fixture can be clamped on the base or released from the base by adjusting the clamping mechanism. It can be understood that when clamping the workpiece, a part of the clamping mechanism overlaps the workpiece, and by adjusting the clamping mechanism, the adjustment fixture can be compacted to the workpiece to prevent the workpiece from falling when flipping, and at the same time, it can also prevent the workpiece from shifting when the welding robot welds the workpiece.

[0011] In some technical schemes, optionally, the clamping component also includes: a first pin; a plurality of first pin holes, which are arranged on the base; a limit block, which is movably arranged on the base; wherein a second pin hole is arranged on the limit block, and the first pin can pass through any of the first pin hole and the second pin hole to fix the position of the limit block, and the limit block is used to limit the movement of the workpiece along the second direction.

[0012] In this technical solution, the clamping component also includes a first latch, a plurality of first pin holes and a limit block, wherein the plurality of first pin holes are arranged on the base, the limit block is movably arranged on the base, the limit block is arranged with a second pin hole, and the first latch can pass through any of the first pin hole and the second pin hole to fix the position of the limit block. In other words, the base is arranged with a plurality of first pin holes, the limit block is arranged with a second pin hole, the first latch can be inserted into the first pin hole and the second pin hole, and the fixed position of the limit block can be adjusted by arranging a plurality of first pin holes on the base. On the one hand, the clamping component can limit the sliding of the workpiece along the second direction through the limit block, further improving the reliability of the workpiece during clamping; on the other hand, the plurality of first pin holes arranged on the base can cooperate with the second pin hole and the first latch, so as to adjust the position of the limit block, thereby improving the flexibility of the limit block.

[0013] In some technical solutions, optionally, the clamping component further includes: a plurality of spheres, which are respectively arranged on both sides of the base along the first direction, and the plurality of spheres are in contact with the workpiece to support the workpiece.

[0014] In this technical solution, the clamping component also includes a plurality of spheres, which are respectively arranged on both sides of the base along a first direction. The surfaces of the plurality of spheres are smooth and the friction coefficient is small. When clamping the workpiece, the plurality of spheres are in direct contact with the workpiece. Since the friction coefficient of the sphere surface is small, it is easier for the staff to adjust the position of the workpiece to meet the clamping requirements, thereby reducing the difficulty of moving the workpiece.

[0015] In some technical solutions, optionally, the clamping device also includes: two positioner assemblies, which are arranged on both sides of the chassis assembly; wherein the positioner assemblies can drive the chassis assembly to rise and fall along a third direction and / or rotate around the first direction.

[0016] In this technical solution, the clamping device also includes two positioner assemblies, which are respectively arranged on both sides of the chassis assembly. The positioner assembly can drive the chassis assembly to rise and fall along the third direction. At the same time, the positioner assembly can also drive the chassis assembly to rotate with the first direction as the axis to achieve the flipping of the workpiece, thereby reducing the welding difficulty of the robot and greatly improving the welding efficiency of the workpiece. In addition, the chassis assembly can drive the workpiece to rise and fall. The reason is that the size of the shielding beam workpiece is large. When the positioner assembly only has the flipping function, when flipping a workpiece with a larger width, the workpiece width is large, resulting in the workpiece sticking to the ground during the flipping process, and the workpiece cannot be flipped. Therefore, the positioner assembly has both lifting and flipping functions. When flipping a workpiece with a larger width, the positioner assembly first lifts the chassis assembly and the workpiece, and then flips it. This can ensure that the workpiece is flipped smoothly and improve the flexibility of the clamping device.

[0017] In some technical solutions, optionally, the positioner assembly includes: a first driving component connected to the chassis assembly and used to drive the chassis assembly to rise and fall along a third direction; a second driving component connected to the chassis assembly and used to drive the chassis assembly to rotate around the first direction.

[0018] In this technical solution, the positioner assembly includes a first driving component and a second driving component, wherein the first driving component is connected to the chassis assembly and is used to drive the chassis assembly to rise and fall along the third direction, and the second driving component is connected to the chassis assembly and is used to drive the chassis assembly to rotate with the first direction as the axis. It can be seen that the positioner assembly has both lifting and flipping functions. When clamping a workpiece with a larger size, the workpiece can still be flipped, which improves the flexibility of the clamping device.

[0019] Specifically, the first driving component is connected to the chain, the chain is connected to the chassis assembly, and the first driving component drives the chain to move in the third direction to achieve the lifting movement of the chassis assembly. The chassis assembly includes a turntable, and the gear on the second driving component is meshed with the gear on the turntable, and the turntable is driven by the second driving component to rotate with the first direction as the axis.

[0020] In some technical solutions, optionally, the clamping device further includes: an end positioning assembly, which is arranged at one end of the chassis assembly and is used to position the workpiece.

[0021] In this technical solution, the clamping device also includes an end positioning assembly, which is arranged at one end of the chassis assembly. When clamping a workpiece, the worker can push one end of the workpiece to the end positioning assembly and use the end positioning assembly to position the workpiece, thereby reducing the difficulty of clamping the workpiece.

[0022] Specifically, the chassis assembly includes a turntable and a support beam. The turntable is arranged at one end of the support beam, the end positioning assembly is arranged at one end of the support beam, and the end positioning assembly is arranged on the inner side of the turntable, so that the workpiece is positioned by using the end positioning assembly. The end positioning assembly arranged on the inner side can also play a role in physical protection of the turntable.

[0023] In some technical solutions, optionally, the chassis assembly includes: a support beam; two turntables, which are arranged on both sides of the support beam; and a rib plate, which connects the support beam and the turntable.

[0024] In this technical solution, the chassis assembly includes a support beam, two turntables and a rib plate, wherein the support beam is the main body of the entire chassis assembly, and the two turntables are arranged on both sides of the support beam. In other words, the main body of the chassis assembly of the present application is the support beam, and the beam structure can reduce the space occupied by the chassis assembly, and at the same time can also improve the load-bearing capacity of the clamping device. In addition, the rib plate connects the support beam and the turntable, that is, the rib plate can be understood as a reinforcing rib, which plays a reinforcing role and further improves the load-bearing capacity of the chassis assembly.

[0025] In some technical solutions, optionally, a guide groove is provided on the side wall of the support beam, and the clamping device also includes: a drag chain, one end of the drag chain is connected to the support beam, and the other end is connected to the sliding beam, the drag chain is arranged in the guide groove, and the drag chain slides along the first direction.

[0026] In this technical solution, a guide groove is provided on the side wall of the support beam, and the clamping device also includes a drag chain, one end of the drag chain is connected to the support beam, and the other end of the drag chain is connected to the sliding beam. The drag chain is arranged in the guide groove, and the guide groove can guide the movement of the drag chain. When the staff moves the clamp assembly, the drag chain can move with the clamp assembly. The drag chain can also protect the cable connected to the clamp assembly. At the same time, by setting the drag chain and the guide groove, the reliability of the reciprocating motion of the clamp assembly is improved.

[0027] In some technical solutions, optionally, the clamping device also includes: a second pin; wherein, a plurality of third pin holes are arranged on the side wall of the support beam, and a fourth pin hole is arranged on the side wall of the sliding beam, and the second pin can pass through any third pin hole and the fourth pin hole to fix the position of the sliding beam.

The staff can move the sliding beam to change the relative position of the clamp assembly and the support beam. When clamping the workpiece, the position of the sliding beam needs to be fixed to fix the position of the clamp assembly. A plurality of third pin holes are arranged on the side wall of the support beam, and the plurality of third pin holes cooperate with the second latch and the fourth latch to fix the clamp assembly to multiple positions of the support beam, thereby improving the flexibility of the clamp assembly.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] The embodiment of the first aspect of the utility model provides a clamping device for robot welding, such as Figure 1 and Figure 2 As shown, it includes: a chassis assembly 1; a plurality of fixture assemblies 2, the plurality of fixture assemblies 2 are spaced apart along a first direction, the fixture assemblies 2 include: a sliding beam 21, slidably mounted on the chassis assembly 1 along the first direction; two clamping components 22, slidably arranged on both sides of the sliding beam 21 along a second direction, the clamping components 22 are used to clamp the workpiece; wherein the first direction is perpendicular to the second direction, and the plurality of fixture assemblies 2 form one or more clamping spaces 3 for accommodating the workpiece.

[0045] The clamping device for robot welding proposed in the present application includes a chassis component 1 and a plurality of clamp components 2, wherein the plurality of clamp components 2 are arranged at intervals along a first direction. The clamp component 2 includes a sliding beam 21 and two clamping components 22, wherein the sliding beam 21 is slidably mounted on the chassis component 1 along a first direction, and the two clamping components 22 are slidably arranged on both sides of the sliding beam 21 along a second direction, wherein the first direction is perpendicular to the second direction, and the plurality of clamp components 2 form one or more clamping spaces 3, and the clamping spaces 3 are used to accommodate the workpiece. That is, along the first direction, the plurality of clamp components 2 are arranged at intervals and slidably mounted on the chassis component 1, and the length of the workpiece is adapted by adjusting the positions of the plurality of clamp components 2, and the width of the workpiece is adapted by adjusting the positions of the two clamping components 22 on the sliding beam 21. That is, by adjusting the positions of the multiple clamp assemblies 2 and the positions of the two clamping parts 22 on the sliding beam 21, the size of the clamping space 3 is adjusted to clamp workpieces of different sizes. In particular, for some workpieces with large size differences, the clamping device proposed in this application can also complete the clamping of such workpieces, thereby achieving precise adaptation to workpieces of different sizes and weights.

[0046] It is understandable that when the length of the workpiece is relatively long, multiple clamp assemblies 2 form a clamping space 3, for example: the workpiece is a shielding beam, and the length of the shielding beam workpiece is greater than or equal to 2500mm, and the clamping device can only form one clamping space 3, which greatly increases the upper limit of the size of the clamping space 3 to accommodate larger-sized workpieces. When the length of the workpiece is relatively short, multiple clamp assemblies 2 form multiple clamping spaces 3, for example: the workpiece is a shielding beam, and the length of the shielding beam workpiece is less than or equal to 2300mm, and the clamping device can simultaneously form two clamping spaces 3, and both clamping spaces 3 can accommodate the shielding beam workpiece, and the clamping device clamps two shielding beam workpieces at the same time, and the welding robot can weld two shielding beam workpieces at the same time, thereby greatly improving the welding efficiency of the shielding beam workpiece.

[0047] In some embodiments, optionally, parameters of the clamping device include: a length greater than or equal to 5000 mm, and a load-bearing capacity greater than or equal to 15 t.

[0048] In this embodiment, the clamping device can clamp a wide range of workpiece sizes. Workpieces with a length greater than or equal to 1000 mm and less than or equal to 5000 mm, and workpieces with a width greater than or equal to 1000 mm and less than or equal to 2100 mm can all be clamped using the clamping device proposed in this application, greatly improving the applicability of the clamping device.

[0049] In some embodiments, optionally, Figure 3 and Fig.10As shown, the clamping component 22 includes: a base 221, which is slidably mounted on the sliding beam 21; an adjusting clamp 222, which is slidably disposed on the base 221; a slideway 223, which is disposed on the base 221, and the adjusting clamp 222 is slidably disposed on the base 221 through the slideway 223; wherein a clamping mechanism 224 is disposed on the adjusting clamp 222, and the adjusting clamp 222 is clamped or loosened by adjusting the clamping mechanism 224.

[0050] In this embodiment, the clamping component 22 includes a base 221, an adjusting fixture 222 and a slideway 223. The base 221 is mounted on the sliding beam 21, and the base 221 can slide relative to the sliding beam 21, so as to adjust the distance between the two clamping components 22 to meet the clamping requirements of shielding beam workpieces of different sizes. The adjusting fixture 222 is slidably disposed on the base 221, and the slideway 223 is disposed on the base 221. The adjusting fixture 222 is slidably disposed on the base 221 through the slideway 223, that is, the adjusting fixture 222 is disposed on the slideway 223, and the slideway 223 is disposed on the base 221. The adjusting fixture 222 can slide back and forth on the slideway 223, so as to realize high-precision clamping of the workpiece by utilizing the sliding of the adjusting fixture 222. In addition, a clamping mechanism 224 is also provided on the adjusting fixture 222, and the adjusting fixture 222 can be pressed against the base 221 or released from the base 221 by adjusting the clamping mechanism 224. It is understandable that when clamping the workpiece, a part of the clamping mechanism 224 overlaps the workpiece, and by adjusting the clamping mechanism 224, the adjusting fixture 222 can be pressed against the workpiece to prevent the workpiece from falling when flipping, and also prevent the workpiece from shifting when the welding robot welds the workpiece.

[0051] In some embodiments, optionally, Figure 3 and Fig.10 As shown, the clamping component 22 also includes: a first latch; a plurality of first pin holes 225, which are arranged on the base 221; a limit block 226, which is movably arranged on the base 221; wherein a second pin hole 227 is arranged on the limit block 226, and the first latch can pass through any of the first pin hole 225 and the second pin hole 227 to fix the position of the limit block 226, and the limit block 226 is used to limit the movement of the workpiece along the second direction.

[0052] In this embodiment, the clamping member 22 further includes a first latch, a plurality of first pin holes 225 and a stopper 226, wherein the plurality of first pin holes 225 are provided on the base 221, the stopper 226 is movably provided on the base 221, the stopper 226 is provided with a second pin hole 227, and the first latch can pass through any of the first pin hole 225 and the second pin hole 227 to fix the position of the stopper 226. In other words, the base 221 is provided with a plurality of first pin holes 225, the stopper 226 is provided with a second pin hole 227, the first latch can be inserted into the first pin hole 225 and the second pin hole 227, and the fixed position of the stopper 226 can be adjusted by providing a plurality of first pin holes 225 on the base 221. On the one hand, the clamping component 22 can limit the sliding of the workpiece along the second direction through the limit block 226, thereby further improving the reliability of the workpiece during clamping; on the other hand, the multiple first pin holes 225 set on the base 221 can cooperate with the second pin hole 227 and the first pin, so as to adjust the position of the limit block 226, thereby improving the flexibility of the limit block 226.

[0053] In some embodiments, optionally, the limit block 226 includes a wedge block. When the limit block 226 is a wedge block, the wedge block can not only limit the movement of the workpiece along the second direction, but also, due to the unique shape of the wedge block, the wedge block can also limit the movement of the workpiece in the height direction, especially when flipping the workpiece, it can prevent the workpiece from falling, thereby further improving the clamping reliability of the workpiece.

[0054] In some embodiments, optionally, Figure 3 and Fig.10 As shown, the clamping component 22 further includes: a plurality of balls 228, which are respectively arranged on both sides of the base 221 along the first direction. The plurality of balls 228 are in contact with the workpiece to support the workpiece.

[0055] In this embodiment, the clamping component 22 also includes a plurality of spheres 228, which are respectively arranged on both sides of the base 221 along the first direction. The surfaces of the plurality of spheres 228 are smooth and the friction coefficient is small. When clamping the workpiece, the plurality of spheres 228 are in direct contact with the workpiece. Since the friction coefficient of the surface of the spheres 228 is small, it is easier for the staff to adjust the position of the workpiece to meet the clamping requirements, thereby reducing the difficulty of moving the workpiece.

[0056] In some embodiments, optionally, Figure 5 and Figure 6 As shown, the clamping device further includes: two positioner assemblies 4, which are arranged on both sides of the chassis assembly 1; wherein the positioner assembly 4 can drive the chassis assembly 1 to rise and fall along the third direction and / or rotate around the first direction.

[0057] In this embodiment, the clamping device also includes two positioner assemblies 4, which are respectively arranged on both sides of the chassis assembly 1. The positioner assembly 4 can drive the chassis assembly 1 to rise and fall along the third direction. At the same time, the positioner assembly 4 can also drive the chassis assembly 1 to rotate with the first direction as the axis to achieve the flipping of the workpiece, thereby reducing the welding difficulty of the robot and greatly improving the welding efficiency of the workpiece. In addition, the chassis assembly 1 can drive the workpiece to rise and fall. The reason is that the size of the shielding beam workpiece is large. When the positioner assembly 4 only has the flipping function, when flipping a workpiece with a larger width, the workpiece width is large, resulting in the workpiece being close to the ground during the flipping process, and the workpiece cannot be flipped. Therefore, the positioner assembly 4 has both the lifting function and the flipping function. When flipping a workpiece with a larger width, the positioner assembly 4 first lifts the chassis assembly 1 and the workpiece, and then flips it. This can ensure that the workpiece is flipped smoothly and improve the flexibility of the clamping device.

[0058] In some embodiments, optionally, the height of the chassis assembly 1 is greater than or equal to 950 mm and less than or equal to 2150 mm.

[0059] In some embodiments, optionally, Figure 4 and Figure 7 As shown, the positioner assembly 4 includes: a first driving component 41, connected to the chassis assembly 1, used to drive the chassis assembly 1 to rise and fall along the third direction; a second driving component 42, connected to the chassis assembly 1, used to drive the chassis assembly 1 to rotate around the first direction.

[0060] In this embodiment, the positioner assembly 4 includes a first driving component 41 and a second driving component 42, wherein the first driving component 41 is connected to the chassis assembly 1 and is used to drive the chassis assembly 1 to rise and fall along the third direction, and the second driving component 42 is connected to the chassis assembly 1 and is used to drive the chassis assembly 1 to rotate with the first direction as the axis. It can be seen that the positioner assembly 4 has both the lifting function and the flipping function. When clamping a workpiece with a larger size, the workpiece can still be flipped, which improves the flexibility of the clamping device.

[0061] Specifically, the first driving component 41 is connected to the chain, and the chain is connected to the chassis assembly 1. The first driving component 41 drives the chain to move in the third direction to achieve the lifting movement of the chassis assembly 1. The chassis assembly 1 includes a turntable 12, and the gear on the second driving component 42 is meshed with the gear on the turntable 12. The turntable 12 is driven by the second driving component 42 to rotate with the first direction as the axis.

[0062] In some embodiments, optionally, Figure 8 and Fig. 9 As shown, the clamping device further includes: an end positioning assembly 5, which is arranged at one end of the chassis assembly 1 and is used to position the workpiece.

[0063] In this embodiment, the clamping device further includes an end positioning assembly 5, which is arranged at one end of the chassis assembly 1. When clamping a workpiece, the worker can push one end of the workpiece to the end positioning assembly 5, and use the end positioning assembly 5 to position the workpiece, thereby reducing the difficulty of clamping the workpiece.

[0064] Specifically, the chassis assembly 1 includes a turntable 12 and a support beam 11. The turntable 12 is arranged at one end of the support beam 11, the end positioning assembly 5 is arranged at one end of the support beam 11, and the end positioning assembly 5 is arranged on the inner side of the turntable 12, so that the workpiece is positioned by using the end positioning assembly 5. The end positioning assembly 5 arranged on the inner side can also play a role in physical protection of the turntable 12.

[0065] In some embodiments, optionally, Figure 1 As shown, the chassis assembly 1 includes: a support beam 11; two turntables 12, which are arranged on both sides of the support beam 11; and a rib plate 13, which connects the support beam 11 and the turntable 12.

[0066] In this embodiment, the chassis assembly 1 includes a support beam 11, two turntables 12 and a rib plate 13, wherein the support beam 11 is the main body of the entire chassis assembly 1, and the two turntables 12 are arranged on both sides of the support beam 11. In other words, the main body of the chassis assembly 1 of the present application is the support beam 11, and the beam structure can reduce the occupied space of the chassis assembly 1, and can also improve the load-bearing capacity of the clamping device. In addition, the rib plate 13 connects the support beam 11 and the turntable 12, that is, the rib plate 13 can be understood as a reinforcing rib, which plays a role of reinforcement, and further improves the load-bearing capacity of the chassis assembly 1.

[0067] In some embodiments, optionally, Figure 1 As shown, the side wall of the support beam 11 is provided with a guide groove 14, and the clamping device also includes: a drag chain 6, one end of the drag chain 6 is connected to the support beam 11, and the other end is connected to the sliding beam 21.
