Description

Technical Field

[0001] The present application relates to the technical field of parts processing equipment, and in particular to a broaching tool for turbine disk parts. Background Art

[0002] Broaching is a process that uses a broach to remove a very thin metal layer from the workpiece, so that the machined surface achieves higher dimensional accuracy and lower surface roughness. During the broaching process, the machined surface is cut and formed at one time, and the broach only has the main motion and no feed motion. It is often used to process non-closed surfaces, especially large surfaces and composite surfaces, such as the tooth processing of turbine disk parts.

[0003] The tooth profile of a turbine disc usually has an oblique angle, so the broaching direction of the tooth profile of the turbine disc has a certain angle with the center axis of the turbine disc. During the broaching process of the tooth profile of the turbine disc, the stability of the turbine disc will affect its processing accuracy, and ordinary clamping cannot guarantee the stability of the turbine disc processing process. Moreover, the tooth profile is evenly distributed on the circumference of the turbine disc. After completing a tooth profile, it needs to be rotated a certain angle before broaching. In this process, the turbine disc needs to be clamped again after rotation, which is a complicated process and difficult to maintain clamping accuracy.

DETAILED DESCRIPTION

[0062] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0064] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] See also Figures 1 to 12 As shown, the embodiment of the present application provides a broaching tool 1 for turbine disk parts, which can stably clamp the turbine disk part 2 to be broached for tooth profile forming, so as to improve the tooth profile broaching forming accuracy. Specifically, the broaching tool 1 for turbine disk parts can be applied to a CNC machine tool with broaching function.

[0066] The broaching tool 1 for turbine disk parts provided in this embodiment includes a base 11 , a dividing mechanism, a supporting mechanism and a clamping mechanism 13 .

[0067] Hereinafter, the above components of the broaching tool 1 for turbine disk parts will be described in detail.

[0068] In the optional solution of this embodiment, Figures 1 to 4 As shown, the indexing mechanism includes a driving assembly 16 and a positioning assembly 15. The positioning assembly 15 is used to position and install the turbine disk part 2, so that the turbine disk part 2 is clamped by the positioning assembly 15. The driving assembly 16 is connected to the positioning assembly 15, and can drive the positioning assembly 15 and the turbine disk part 2 to rotate. Specifically, after the turbine disk is fixed by the positioning assembly 15, the tooth profile broaching process at the current tooth profile angle is completed, and then the positioning assembly 15 is driven by the driving assembly 16 to rotate a predetermined angle, and the positioning assembly 15 drives the turbine disk part 2 to rotate synchronously by a predetermined angle, so that the turbine disk part 2 rotates to the broaching position of the next tooth profile, so that the broaching tool can perform the next tooth profile broaching process on the turbine disk part 2, and so on, until the broaching process of all tooth profiles of the turbine disk part 2 is completed.

[0069] The indexing mechanism may be, for example, an existing indexing plate, a machine tool component that can clamp a workpiece and rotate, index, and position the workpiece.

[0070] In this embodiment, Fig.10As shown, the driving assembly 16 of the dividing mechanism includes a turntable 161 and a table 160. The turntable 161 includes a power output assembly and an output shaft. The power output assembly can drive the output shaft to rotate. The output shaft of the turntable 161 is connected to the table 160, so that the turntable 161 can drive the table 160 to rotate through the output shaft.

[0071] The positioning assembly 15 and the table 160 are detachably connected, so that the positioning assembly 15 and the turbine disk part 2 can be connected first, and then the whole connected between the two can be connected to the positioning assembly 15, which improves the convenience of disassembly and assembly between the turbine disk part 2 and the dividing mechanism.

[0072] Optionally, in order to facilitate the fixed installation of the indexing mechanism on the CNC machine tool for use, the circumferential side wall of the turntable 161 is further provided with a positioning groove 162, so that the broaching tool 1 for turbine disk parts can be installed on the CNC machine tool through the positioning groove 162.

[0073] In this embodiment, the indexing mechanism and the clamping mechanism 13 are both arranged on the base 11, so as to support the indexing mechanism and the clamping mechanism 13 through the base 11. Specifically, the driving assembly 16 of the indexing mechanism is arranged on the base 11, and the positioning assembly 15 is located on the top of the driving assembly 16. The base 11 can be detachably connected to the machine tool to realize the detachable connection of the broaching tool 1 for turbine disk parts relative to the machine tool.

[0074] In this embodiment, Fig.11 and Fig.12 As shown, the positioning assembly 15 includes a support disc 151 and a gland disc 150. The support disc 151 is used to support the bottom of the turbine disc part 2, and the gland disc 150 is used to be pressed on the top of the turbine disc part 2, so that the turbine disc part 2 is clamped between the support disc 151 and the gland disc 150.

[0075] The support plate 151 is arranged on the table 160, that is, the support plate 151 is detachably connected to the table 160, so that the positioning assembly 15 is detachably connected to the table 160. The turbine disk part 2 is supported and positioned on the table 160 by the support plate 151, which can reduce the possibility of deformation of the turbine disk part 2 during the drawing process.

[0076] The clamping mechanism 13 can be raised and lowered at the top of the pressure cover plate 150 to press the pressure cover plate 150 toward the table 160, so that the clamping force of the clamping mechanism 13 is transmitted to the turbine disk part 2 through the pressure cover plate 150, avoiding the clamping mechanism 13 from applying the clamping force directly on the turbine disk part 2 and causing damage to the turbine disk part 2. In addition, the clamping force can be applied to the turbine disk part 2 more evenly.

[0077] In this embodiment, in order to make the turbine disk part 2 more stably installed on the table 160 after being clamped by the positioning assembly 15, the support disk 151, the gland disk 150 and the table 160 are all provided with a first positioning pin hole 144 and a second positioning pin hole 145, and the support disk 151, the gland disk 150 and the table 160 are pinned together through the first positioning pin hole 144 and the positioning pin 140, and the support disk 151, the gland disk 150 and the table 160 are pinned together through the second positioning pin hole 145 and the expansion pin 142.

[0078] On the one hand, by pinning the positioning pin 140 and the expansion pin 142, the circumferential positioning of the support disk 151 and the pressure cover disk 150 relative to the table 160 can be achieved, thereby achieving the circumferential positioning of the turbine disk part 2 relative to the table 160. On the other hand, by selecting one of the two pinning locations as the positioning pin and the other as the expansion pin, the support disk 151, the pressure cover disk 150 and the table 160 can be pinned and positioned at one location by the positioning pin first, and on this basis, the second positioning pin holes 145 of the three can be easily aligned, and then the expansion pins can be pinned and expanded in the second positioning pin holes 145 of the three, so as to achieve the radial positioning of the three, thereby achieving the radial positioning of the turbine disk part 2 relative to the table 160. Therefore, under the joint action of the positioning pin 140 and the expansion pin 142, it can be ensured that the turbine disk part 2 clamped by the positioning assembly 15 is stably installed on the table 160, and it can be ensured that the positioning accuracy is high both in the circumferential direction and radial direction along the table 160.

[0079] In order to enable the support disk 151 and the pressure cover disk 150 to clamp and position the turbine disk part 2 more stably, the turbine disk part 2 and the pressure cover disk 150 are provided with a first locking through hole, and the turbine disk part 2 and the pressure cover disk 150 are connected to the first fastening member 141 via the first locking through hole, and the turbine disk part 2 and the pressure cover disk 150 are provided with a second locking through hole 143, and the turbine disk part 2 and the pressure cover disk 150 are connected to each other via the first locking through hole and the second locking through hole 143.

[0080] Thus, it is possible to ensure that the turbine disk part 2 is firmly connected to the support disk 151 and the gland disk 150 at the same time, improve the positioning accuracy of the turbine disk part 2 relative to the support disk 151 and the gland disk 150, and realize the positioning of the turbine disk part 2 in the circumferential, axial and radial directions. At the same time, the turbine disk part 2 is connected to the positioning assembly 15 as a whole and then positioned and connected to the table 160 through the positioning pin 140 and the expansion pin 142.

[0081] Optionally, both the first fastening member 141 and the second fastening member may be bolts.

[0082] In the optional solution of this embodiment, Fig. 9As shown, the clamping mechanism 13 can be raised and lowered at the top of the positioning assembly 15 to press the turbine disk part 2 toward the positioning assembly 15. Specifically, when the clamping mechanism 13 rises to a position disengaged from the positioning assembly 15 relative to the positioning assembly 15, the clamping mechanism 13 can release the turbine disk part 2. In this state, the driving assembly 16 can drive the positioning assembly 15 and the turbine disk part 2 to rotate synchronously to adjust the processing angle of the turbine disk part 2.

[0083] When the clamping mechanism 13 is lowered relative to the positioning assembly 15 to a position in contact with the positioning assembly 15, the clamping mechanism 13 can clamp the positioning assembly 15, thereby clamping the turbine disk part 2. In this state, it is suitable for broaching the turbine disk part 2. Specifically, the broaching tool usually broaches roughly from the top to the bottom of the indexing mechanism. Thus, by clamping the turbine disk part 2 through the clamping mechanism 13, the displacement of the turbine disk part 2 along the height direction of the indexing mechanism (that is, the axial direction of the turbine disk part 2) during the broaching process can be avoided, so as to improve the clamping stability of the turbine disk part 2, and further improve the tooth broaching forming accuracy of the turbine disk part 2. It is worth emphasizing that in the process of the broaching tool performing helical gear processing, although the broaching direction of the broaching tool forms an angle with the axial direction of the turbine disk part 2, it can also be considered as broaching roughly from the top to the bottom of the indexing mechanism.

[0084] In this embodiment, the pressing mechanism 13 includes a pressing beam 132 , a pressing support 130 and a pressing driving member 131 .

[0085] The clamping pillar 130 is disposed at the bottom of the clamping beam 132, and the clamping driving member 131 is connected between the clamping pillar 130 and the clamping beam 132. The clamping driving member 131 can drive the clamping beam 132 to rise and fall relative to the positioning assembly 15. Specifically, the clamping pillar 130 is disposed on the base 11, and the clamping driving member 131 is connected between the top of the clamping pillar 130 and the clamping beam 132. The clamping driving member 131 is, for example, a cylinder or an oil cylinder.

[0086] In the present embodiment, there are two clamping mechanisms 13, and the two clamping mechanisms 13 are arranged side by side and spaced apart on both sides of the positioning assembly 15. Specifically, when the turbine disk part 2 is clamped in the positioning assembly 15, the two clamping mechanisms 13 are respectively located on both sides of the axis of the turbine disk part 2, and the clamping beams 132 of the two clamping mechanisms 13 are arranged parallel to each other to improve the uniformity of the distribution of the clamping force applied to the turbine disk part 2.

[0087] In the present embodiment, for each clamping mechanism 13, the middle part of the clamping beam 132 in the length direction faces the positioning assembly 15, and both ends of the clamping beam 132 in the length direction are connected with clamping pillars 130 and clamping driving members 131, so as to ensure that the clamping beam 132 is pressed straight down toward the positioning assembly 15. Compared with the solution in which the clamping driving member 131 applies force to the clamping beam 132 at a single point, the risk of the clamping beam 132 being skewed during the pressing process and causing the clamping force to not be applied in place can be significantly reduced.

[0088] Optionally, the pressing driving member 131 is a pneumatic cylinder, an oil cylinder or an electric slide, etc.

[0089] In this embodiment, a force-applying protrusion 133 is provided at the bottom of the clamping beam 132, and the clamping beam 132 contacts the positioning assembly 15 through the force-applying protrusion 133. Specifically, compared with the solution in which the clamping beam 132 contacts the positioning assembly 15 directly, the solution in which the clamping beam 132 contacts the positioning assembly 15 through the force-applying protrusion 133 improves the surface contact into line contact or even point contact, and even if the clamping beam 132 is deflected, it can ensure that a vertical downward clamping force is applied to the positioning assembly 15 and the turbine disk part 2, and no component force along the circumference of the turbine disk part 2 is generated, which can effectively avoid the occurrence of problems such as unstable clamping caused by the component force along the circumference of the turbine disk part 2, and improve the reliability of the press-fitting of the turbine disk part 2.

[0090] In the optional scheme of this embodiment, during the broaching process, the broaching force borne by the turbine disk part 2 at the contact point with the broach is the largest, so the deformation of the turbine disk part 2 at this point is the largest. In order to avoid deformation here, it is necessary to strengthen support and protection for the broaching position.

[0091] As a strengthening means for supporting and protecting the broaching position of the turbine disk part 2, such as Figure 2 As shown, the broaching tool 1 for turbine disk parts includes a supporting mechanism, and the supporting mechanism includes a broaching supporting assembly 10 .

[0092] The broaching support assembly 10 is movably disposed at the bottom of the positioning assembly 15 corresponding to the broaching position to support the turbine disk part 2 toward the positioning assembly 15. Specifically, the broaching support assembly 10 is movably disposed at the bottom of the support disk 151 corresponding to the broaching position, and the broaching support assembly 10 can be raised to a position abutting against the bottom of the support disk 151, and can be lowered to a position away from the bottom of the support disk 151.

[0093] When the broaching support assembly 10 descends to a position away from the support disk 151, it is suitable for adjusting the tooth processing angle of the turbine disk part 2. That is, in this state, the driving assembly 16 can drive the positioning assembly 15 and the turbine disk part 2 to rotate synchronously to achieve the purpose of accurately controlling the tooth positioning of the turbine disk part 2.

[0094] When the broaching support assembly 10 rises to a position abutting against the bottom of the support disk 151, the support disk 151 can be supported to achieve the purpose of supporting and strengthening the broaching position of the turbine disk part 2, thereby preventing the turbine disk part 2 and the support disk 151 from being deformed at the broaching position due to the broaching force, thereby improving the tooth processing accuracy of the turbine disk part 2. It is worth emphasizing that by adjusting the lifting degree of the broaching support assembly 10, the support degree of the broaching position of the turbine disk part 2 can be adjusted, so that the support degree of the broaching support assembly 10 can be adjusted according to the deformation of the broaching position of the turbine disk part 2, thereby achieving the purpose of accurately adjusting the support and strengthening degree of the broaching position.

[0095] In this embodiment, the broaching support assembly 10 is supported between the base 11 and the positioning assembly 15, that is, the broaching support assembly 10 is arranged on the base 11, and the broaching support assembly 10 can be raised and lowered relative to the positioning assembly 15 to achieve the purpose of supporting and strengthening the broaching position of the positioning assembly 15 and the turbine disk part 2.

[0096] In this embodiment, Figure 5 and Figure 6 As shown, the broaching support assembly 10 includes a first fixed support block 101 , a first movable support block 100 and a first transmission slide block 105 .

[0097] The first fixed support block 101 is arranged on the base 11, and the first movable support block 100 is movably connected to the top of the first fixed support block 101. Specifically, the first movable support block 100 is slidably connected to the first fixed support block 101 along the height direction of the positioning component 15. For example, a first sliding pair 104 parallel to the height direction of the positioning component 15 is formed between the first movable support block 100 and the first fixed support block 101.

[0098] A first slide groove 106 is formed between the bottom surface of the first movable support block 100 and the top surface of the first fixed support block 101, and the height of the first slide groove 106 gradually increases along a first predetermined direction, and the first predetermined direction is perpendicular to the height direction of the first slide groove 106. Specifically, the height direction of the first slide groove 106 is parallel to the height direction of the positioning assembly 15, and the first predetermined direction may be a direction tangential to the circumference of the turbine disk part 2 at the broaching position, or the first predetermined direction may be a radial direction of the turbine disk part 2.

[0099] In order to make the height of the first slide slot 106 gradually increase along the first predetermined direction, at least one of the bottom surface of the first movable support block 100 and the top surface of the first fixed support block 101 is formed as an inclined surface, which is not perpendicular to the height direction of the positioning assembly 15.

[0100] The first transmission slider 105 is disposed in the first slide groove 106 and can move in the first slide groove 106 along the first predetermined direction, so as to drive the first movable support block 100 to rise and fall relative to the first fixed support block 101 during the movement. Specifically, the first transmission slider 105 is formed with, for example, a first surface that fits with the bottom surface of the first movable support block 100 and a second surface that fits with the top surface of the first fixed support block 101. The first transmission slider 105 is also, for example, in the shape of a roller.

[0101] Therefore, when the first transmission slider 105 moves along the first predetermined direction, the first movable support block 100 descends relative to the first fixed support block 101 , which can reduce the supporting force on the support disk 151 and the turbine disk part 2 .

[0102] When the first transmission slider 105 moves in the opposite direction of the first predetermined direction, the first movable support block 100 rises relative to the first fixed support block 101 , thereby increasing the supporting force for the support disk 151 and the turbine disk part 2 .

[0103] In this embodiment, the broaching support assembly 10 further includes a first lifting drive member 102 and a first position detection member 103 .

[0104] The first lifting drive member 102 is connected to the first transmission slider 105, and can drive the first transmission slider 105 to move along the first predetermined direction. Specifically, the first lifting drive member 102 can drive the first transmission slider 105 to move in the forward and reverse directions along the first predetermined direction, so that the moving direction and amount of the first transmission slider 105 can be precisely controlled by controlling the first lifting drive member 102, thereby achieving precise control of the support degree of the broaching support assembly 10.

[0105] The first position detection component 103 is relatively fixedly arranged with respect to the first fixed support block 101 , and the first position detection component 103 is electrically connected with the first lifting drive member 102 . Through the detection result of the first position detection component 103 , the first lifting drive member 102 is controlled more accurately and conveniently.

[0106] The first position detection component 103 is used to detect the deformation of the pulling position of the positioning component 15. Specifically, the first lifting drive component 102 can be controlled according to the deformation of the pulling position of the positioning component 15, that is, according to the deformation of the pulling position of the support plate 151, so that the support force adjustment amount matches the deformation of the pulling position of the support plate 151.

[0107] In an optional solution of this embodiment, during the broaching process, deformation may also occur at other positions of the turbine disk part 2 except the broaching position. In order to reduce the overall deformation of the positioning assembly 15 and the turbine disk part 2, as shown in FIG. Figure 4 As shown, the support mechanism further includes a circumferential support assembly 12, which is movably disposed at the bottom of the positioning assembly 15, and is supported between the positioning assembly 15 and the driving assembly 16 to support the turbine disk part 2 toward the positioning assembly 15. Specifically, the circumferential support assembly 12 is movably disposed at the bottom of the support disk 151 corresponding to a position other than the broaching position, and the circumferential support assembly 12 can rise to a position abutting against the bottom of the support disk 151, and can fall to a position away from the bottom of the support disk 151.

[0108] When the circumferential support assembly 12 descends to a position away from the support disk 151, it is suitable for adjusting the tooth processing angle of the turbine disk part 2. That is, in this state, the drive assembly 16 can drive the positioning assembly 15 and the turbine disk part 2 to rotate synchronously to achieve the purpose of precise tooth positioning of the turbine disk part 2.

[0109] When the circumferential support assembly 12 rises to a position abutting against the bottom of the support disk 151, the support disk 151 can be supported to achieve the purpose of supporting and strengthening other positions of the turbine disk part 2 except the broaching position, thereby avoiding deformation of the turbine disk part 2 and the support disk 151 at other positions except the broaching position, reducing the overall deformation of the support disk 151 and the turbine disk part 2, and further improving the tooth processing accuracy of the turbine disk part 2. It is worth emphasizing that by adjusting the degree of lifting and lowering of the circumferential support assembly 12, the degree of support for other positions of the turbine disk part 2 except the broaching position can be adjusted, so that the degree of support of the circumferential support assembly 12 can be adjusted according to the overall deformation of the turbine disk part 2, thereby achieving the purpose of accurately adjusting the overall support and strengthening degree of the turbine disk part 2.

[0110] In this embodiment, there are multiple circumferential support assemblies 12, and the multiple circumferential support assemblies 12 are arranged in sequence and at intervals along the circumference of the positioning assembly 15, so that multi-point support is achieved for the positioning assembly 15 and the turbine disk part 2 through the multiple circumferential support assemblies 12, thereby achieving the purpose of more effectively reducing the overall shape variable of the positioning assembly 15 and the turbine disk part 2.

[0111] Optionally, the number of the circumferential support assemblies 12 may be four, and the four circumferential support assemblies 12 are supported at four corners of the support plate 151 .

[0112] In this embodiment, Figure 7 and Figure 8 As shown, the circumferential support assembly 12 includes a second fixed support block 121 , a second movable support block 120 and a second transmission slider 123 .

[0113] The second fixed support block 121 is disposed on the driving assembly 16, and the second movable support block 120 is movably connected to the top of the second fixed support block 121. Specifically, the second fixed support block 121 is disposed on the turntable 161, and the second movable support block 120 and the second fixed support block 121 are both located at the side of the table 160. The second movable support block 120 is slidably connected with the second fixed support block 121 along the height direction of the positioning assembly 15, for example, a second sliding pair 124 parallel to the height direction of the positioning assembly 15 is formed between the second movable support block 120 and the second fixed support block 121.

[0114] A second slide groove 122 is formed between the bottom surface of the second movable support block 120 and the top surface of the second fixed support block 121. The height of the second slide groove 122 gradually increases along the second predetermined direction, and the second predetermined direction is perpendicular to the height direction of the second slide groove 122. Specifically, the height direction of the second slide groove 122 is parallel to the height direction of the positioning assembly 15. The second predetermined direction may be a direction tangential to the circumference of the turbine disk part 2 at the location of the circumferential support assembly 12, or the second predetermined direction may be a radial direction of the turbine disk part 2. It is worth emphasizing that the second predetermined direction of each circumferential support assembly 12 may be the same or different.

[0115] In order to make the height of the second slide slot 122 gradually increase along the second predetermined direction, at least one of the bottom surface of the second movable support block 120 and the top surface of the second fixed support block 121 is formed as an inclined surface, which is not perpendicular to the height of the positioning assembly 15 .

[0116] The second transmission slider 123 is disposed in the second slide groove 122 and can move in the second slide groove 122 along the second predetermined direction, so as to drive the second movable support block 120 to rise and fall relative to the second fixed support block 121 during the movement. Specifically, the second transmission slider 123 is formed with, for example, a third surface that fits with the bottom surface of the second movable support block 120 and a fourth surface that fits with the top surface of the second fixed support block 121. The second transmission slider 123 is also in the shape of a roller, for example.

[0117] Therefore, when the second transmission slider 123 moves along the second predetermined direction, the second movable support block 120 descends relative to the second fixed support block 121 , which can reduce the supporting force on the support disk 151 and the turbine disk part 2 .

[0118] When the second transmission slider 123 moves in the opposite direction of the second predetermined direction, the second movable support block 120 rises relative to the second fixed support block 121 , thereby increasing the supporting force for the support disk 151 and the turbine disk part 2 .

[0119] In this embodiment, the circumferential support assembly 12 further includes a second lifting drive member 125 and a second position detection member 126 .

[0120] The second lifting drive member 125 is connected to the second transmission slider 123, and can drive the second transmission slider 123 to move along the second predetermined direction. Specifically, the second lifting drive member 125 can drive the second transmission slider 123 to move in the forward and reverse directions along the second predetermined direction, so that the moving direction and amount of the second transmission slider 123 can be precisely controlled by controlling the second lifting drive member 125, thereby achieving precise control of the support degree of the circumferential support assembly 12.

[0121] The second position detection component 126 is fixedly arranged relative to the second fixed support block 121 , and is electrically connected to the second lifting drive member 125 . The second lifting drive member 125 is controlled more accurately and conveniently through the detection result of the second position detection component 126 .

[0122] The second position detection component 126 is used to detect the deformation of the positioning component 15. Specifically, the second lifting drive component 125 can be controlled according to the deformation of the positioning component 15 at other positions except the drawing position, that is, the deformation of the support plate 151 at the other position, so that the support force adjustment amount matches the deformation of the support plate 151 at the other position.

[0123] Furthermore, the first lifting drive member 102 and the second lifting drive member 125 can be electrically connected to the driving assembly 16 respectively. When the driving assembly 16 needs to drive the positioning assembly 15 to drive the turbine disk part 2 to rotate, the first lifting drive member 102 is controlled to drive the first movable support block 100 to descend, and the second lifting drive member 125 is controlled to drive the second movable support block 120 to descend.

[0124] Optionally, the first position detecting member 103 and the second position detecting member 126 are proximity switches respectively.
