[0002] During the use of mechanical equipment, the precision and performance of its components directly affect the quality of the final product. After a period of operation, the precision of these components decreases. Therefore, regularly inspecting and calibrating the components of mechanical equipment is a crucial step in ensuring product quality. This not only improves production efficiency but also guarantees that product quality meets standards, thereby enhancing market competitiveness.

[0027] This utility model provides a height adjustment mechanism and a packaging repair device, including a base, a guide assembly, a worktable, and a height lifting assembly. The guide assembly is disposed on the base, and the worktable is located above the base for supporting parts.

This high precision of the height adjustment mechanism enables accurate adjustment of component positions, improving the precision of the machinery, and ultimately enhancing product quality and production efficiency.

[0044] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] like Figures 1-3 As shown, this embodiment provides a height adjustment mechanism, which includes a base 1, a guide assembly 2, a worktable 3, and a height lifting assembly 4. The guide assembly 2 is disposed on the base 1, and the worktable 3 is located above the base 1 for supporting components. The worktable 3 is slidably connected to the guide assembly 2 in the vertical direction, and the guide assembly 2 restricts the movement of the worktable 3 in the horizontal direction. The height lifting assembly 4 includes a drive component 41, a first drive member 42, and a second drive member 43. The first drive member 42 is slidably connected to the base 1 in a first direction, and the second drive member 43 is slidably connected to the first drive member 42 in a second direction. The second direction is inclined relative to the first direction in the vertical plane, and the second drive member 43 is installed at the bottom of the worktable 3. The drive component 41 is disposed on the base 1 and is drivenly connected to the first drive member 42. The drive component 41 is used to drive the first drive member 42 to move in the first direction, thereby driving the worktable 3 to rise and fall.

[0049] During operation, the drive component 41 drives the first drive member 42 to move along a first direction, while the second drive member 43 slides relative to the first drive member 42. Because the guide assembly 2 restricts the horizontal displacement of the second drive member 43 and the worktable 3, the second drive member 43 and the worktable 3 move vertically, thus achieving the lifting and lowering of the worktable 3. This height adjustment mechanism allows the worktable 3 to move slightly vertically, precisely adjusting its vertical position. This high precision allows for accurate adjustment of component positions, improving the precision of the machinery, product quality, and production efficiency.

[0050] Specifically, the first direction is X, the second direction is Y, and the vertical direction is Z. The first direction is a direction within a horizontal plane, and the second direction is a direction within a vertical plane containing the first direction. The second direction is inclined relative to the first direction, and the angle of this inclination is determined based on specific circumstances; this embodiment does not limit this. The second driving member 43 has an "L"-shaped cross-section, forming a first mounting surface and a second mounting surface. The first mounting surface is fixed to the bottom of the worktable 3. Threaded holes are correspondingly provided on the first mounting surface and the worktable 3. Screws are passed through these threaded holes to connect the second driving member 43 to the worktable 3. The second mounting surface is slidably connected to the first driving member 42 along the second direction, thereby driving the worktable 3 to rise and fall.

[0051] Preferably, the drive component 41 includes a lead screw 411 and a lead screw support 412. The lead screw support 412 is mounted on the base 1, and the lead screw 411 is rotatably connected to the lead screw support 412. The first drive component 42 is provided with a first threaded hole extending in a first direction. The lead screw 411 is threadedly connected to the first threaded hole. The lead screw 411 can thread-drive the first drive component 42 to move in the first direction. The lead screw support 412 can support the lead screw 411 and restrict the movement of the lead screw 411 in the first direction.

[0052] Specifically, in this embodiment, the lead screw 411 is a 30-degree trapezoidal lead screw. The lead screw support 412 is installed along the first direction on the edge of one side of the base 1 and is connected to the base 1 by screws or bolts. In other embodiments, the lead screw 411 can also be a 45-degree trapezoidal lead screw or other shapes of lead screw, and a structure such as a snap-fit ​​can be used instead of screws or bolts. A bearing seat hole extending along the first direction is provided on the lead screw support 412, and a first rolling bearing is installed in the bearing seat hole. The lead screw 411 is passed through the shaft hole on the first rolling bearing and is tightly fitted with the shaft hole, so that the lead screw 411 is rotatably connected to the lead screw support 412 through the first rolling bearing. A first threaded hole extending along the first direction is provided on the first driving member 42, and the lead screw 411 is threadedly connected to the first threaded hole. By rotating the lead screw 411, the first driving member 42 can be driven to move along the first direction.

[0053] Preferably, the drive component 41 further includes a handwheel 415, which is connected to the end of the lead screw 411 away from the first drive component 42. By rotating the handwheel 415, the operator can drive the lead screw 411 to rotate, thereby driving the first drive component 42.

[0054] Specifically, the handwheel 415 has a cylindrical structure. In this embodiment, a mounting hole is provided along the axial direction of the handwheel 415, and a threaded hole is provided along its circumference. A groove is provided circumferentially at the end of the lead screw 411 away from the first driving member 42. The lead screw 411 is installed in the mounting hole with the groove corresponding to the threaded hole. A screw is threaded into the threaded hole and abuts against the groove to fix the handwheel 415 and the lead screw 411. The handwheel 415 can be made of rubber or resin. A frosted texture can be provided on the circumferential sidewall of the handwheel 415 to increase the friction between the hand and the handwheel 415 when the handwheel 415 is rotated, preventing slippage, improving ease of operation, and improving adjustment accuracy.

[0055] Preferably, such as Figure 3 and Figure 4 As shown, the drive component 41 also includes a locking block 413 and a locking handle 414. The locking block 413 is connected to one side of the lead screw support 412. The locking block 413 is provided with a locking hole 4131 and a gap 4132 communicating with the locking hole 4131. The lead screw 411 passes through the locking hole 4131. A through hole 4134 is provided on one side of the gap 4132, and a second threaded hole 4133 is provided on the other side. The locking handle 414 passes through the through hole 4134 and the gap 4132 and is threadedly connected to the second threaded hole 4133. The locking block 413 and the locking handle 414 can lock and fix the lead screw 411 to prevent the lead screw 411 from rotating when the operator is not operating it.

[0056] Specifically, the locking block 413 has a locking hole 4131 along the first direction, and the end of the lead screw 411 facing away from the first driving member 42 passes through the locking hole 4131 and is connected to the handwheel 415. A gap 4132 communicating with the locking hole 4131 is provided along the circumference of the locking hole 4131. A through hole 4134 is provided on one side of the gap 4132, and a second threaded hole 4133 is provided on the other side. The locking handle 414 is L-shaped, and a thread is provided at one end. The threaded end of the locking handle 414 passes through the through hole 4134 and the gap 4132 and is threadedly connected to the second threaded hole 4133. When the locking handle 414 is rotated, increasing the gap 4132, the inner diameter of the locking hole 4131 increases, achieving a clearance fit between the lead screw 411 and the locking hole 4131, allowing the lead screw 411 to rotate within the locking hole 4131. Conversely, when the locking handle 414 is rotated in the opposite direction, decreasing the gap 4132, the inner diameter of the locking hole 4131 decreases, achieving a tight fit between the lead screw 411 and the locking hole 4131, thus locking and fixing the lead screw 411. The locking block 413 is mounted on the side of the lead screw support 412 facing away from the first driving member 42 by screws.

[0057] More preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, the height adjustment mechanism also includes a position display 5, which is connected to one side of the lead screw support 412. The position display 5 is provided with a detection hole, and the lead screw 411 is rotatably connected to the detection hole. The position display 5 can measure and display the distance of rotation of the lead screw 411, thereby improving the adjustment accuracy.

[0058] Specifically, the position display 5 is connected to the side of the locking block 413 facing away from the lead screw support 412. A positioning post is provided on the side of the position display 5 facing the locking block 413, and a positioning hole is provided at the position corresponding to the positioning post on the locking block 413. The positioning post and the positioning hole are interference-fitted, and external pressure is used to embed the positioning post into the positioning hole, thus fixing the position display 5. The position display 5 has a detection hole coaxial with the locking hole 4131 along a first direction. A second rolling bearing is provided on one side of the detection hole, and a detection unit is located on the other side for detection. The end of the lead screw 411 away from the first driving member 42 is passed through the shaft hole on the second rolling bearing and tightly fitted with the shaft hole, so that the lead screw 411 is rotatably connected to the detection hole through the second rolling bearing. The detection unit can measure and display the distance rotated by the lead screw 411. It should be noted that the position display 5 is prior art, and its working principle will not be described in detail here.

[0059] Preferably, such as Figure 1 , Figure 3 and Figure 5As shown, the height lifting assembly 4 further includes a first slider 45 and a first slide rail 44 extending along a first direction. The first slide rail 44 is mounted on the base 1. A first drive member 42 is connected to the first slider 45, and the first slider 45 is slidably connected to the first slide rail 44. And / or the height lifting assembly 4 further includes a second slider 47 and a second slide rail 46 extending along a second direction. The second slide rail 46 is mounted on the first drive member 42. A second drive member 43 is connected to the second slider 47, and the second slider 47 is slidably connected to the second slide rail 46. The first slider 45 and the first slide rail 44 can improve the accuracy of the first drive member 42 moving along the first direction, and the second slider 47 and the second slide rail 46 can improve the accuracy of the second drive member 43 moving along the vertical direction.

[0060] Specifically, the first slide rail 44 is elongated. In this embodiment, the first slide rail 44 is fixed to the base 1 along the first direction by screws. In other embodiments, the first slide rail 44 can also be fixed to the base 1 by adhesive or snap-fit. Taking adhesive as an example, an adhesive backing is provided on the side of the first slide rail 44 facing the base 1, and the first slide rail 44 is glued to the base 1 by the adhesive backing. The first driving member 42 is connected to the first slider 45 by studs. Threaded holes are provided on the top of the first slider 45 and the bottom of the first driving member 42, respectively. The two ends of the studs are connected to the threaded holes on the top of the first slider 45 and the bottom of the first driving member 42, respectively, to fix the first slider 45 and the first driving member 42. In this embodiment, there are two first sliders 45. In other embodiments, there can be three or more first sliders 45. The first slider 45 is provided with a first sliding groove. The cross-section of the first sliding groove is U-shaped. The first sliding groove is connected to the first slide rail 44, and the first driving member 42 moves in the first direction by cooperating with the first slide rail 44.

[0061] The second slide rail 46 is also elongated. In this embodiment, the second slide rail 46 is fixed to the side wall of the first drive member 42 along the second direction by screws. In other embodiments, the second slide rail 46 can also be fixed to the base 1 by adhesive or snap-fit. The second drive member 43 is connected to the second slider 47 by screws. In this embodiment, there are two second sliders 47, but in other embodiments, there can be three or more second sliders 47. The second slider 47 is provided with a second sliding groove, the cross-section of which is U-shaped. The second sliding groove is connected to the second slide rail 46 and moves along the second slide rail 46 through the cooperation with the second slide rail 46. The movement of the first drive member 42 in the first direction drives the second guide rail to move in the first direction. Since the second guide rail is set along the second direction, the movement of the second guide rail in the first direction will drive the second slider 47 to move in the second direction. The guide component 2 restricts the horizontal movement of the second slider 47, thereby causing the second slider 47 to move in the vertical direction, which in turn drives the second drive member 43 to move in the vertical direction, ultimately realizing the lifting and lowering of the worktable 3.

[0062] More preferably, the first driving member 42 includes a first connecting plate 421 and a second connecting plate 422 that are vertically connected, a first slider 45 connected to the bottom of the first connecting plate 421, and a second slide rail 46 connected to the side wall of the second connecting plate 422.

[0063] Specifically, the first connecting plate 421 extends horizontally along the first direction, and the second connecting plate 422 extends vertically along the first direction. The cross-section of the first connecting plate 421 along the first direction is "L"-shaped, forming a third mounting surface and a fourth mounting surface. The third mounting surface is connected to the first slider 45, and the fourth mounting surface is provided with a first threaded hole extending along the first direction. The lead screw 411 is threaded into the first threaded hole, driving the first connecting plate 421 to move along the first direction. The first connecting plate 421 is connected to the second connecting plate 422 by screws.

[0064] Preferably, such as Figure 1 and Figure 2 As shown, the guide assembly 2 includes a support 21, a guide shaft 22 extending vertically, and a linear bearing 23. The support 21 is mounted on the base 1, one end of the guide shaft 22 is mounted on the support 21, the worktable 3 is provided with a guide hole, the linear bearing 23 is connected to the guide hole, and the linear bearing 23 is sleeved on the other end of the guide shaft 22, which enables the worktable 3 to move more smoothly in the vertical direction.

[0065] Specifically, the support 21 is mounted on the base 1 with screws. The support 21 has a guide shaft hole in the vertical direction. One end of the guide shaft 22 has a mounting surface. The end of the guide shaft 22 with the mounting surface is placed in the guide shaft hole. A threaded hole is provided on the side wall of the support 21. A screw is passed through the threaded hole and abuts against the mounting surface to fix the guide shaft 22. The worktable 3 has a guide hole that communicates with the shaft hole of the linear bearing 23. The linear bearing 23 has a flange, and threaded holes are provided on the flange and the worktable 3 respectively. Screws pass through the threaded holes on the flange and the worktable 3 to connect the linear bearing 23 to the worktable 3. The linear bearing 23 is fitted onto the other end of the guide shaft 22, allowing the worktable 3 to move vertically along the guide shaft 22. One or more guide components 2 can be provided; this embodiment does not limit this.

[0066] Preferably, such as Figure 3 and Figure 6 As shown, the height adjustment mechanism also includes an indicator component 6, which includes a scale 61 and an indicator 62. One of the scale 61 and the indicator 62 is connected to the base 1, and the other is connected to the worktable 3. The scale 61 extends vertically, and the indicator 62 is located on one side of the scale 61, which can display the height of the worktable 3 for greater accuracy.

[0067] Specifically, the scale 61 is fixed to the first mounting plate 63. Adhesive is provided on the back of the scale 61, which is used to adhere the scale 61 to the first mounting plate 63. The first mounting plate 63 is fixed to the edge of the base 1 where the lead screw support 412 is located, and the scale 61 on it extends vertically. In this embodiment, a first elongated through hole is provided at the connection point between the first mounting plate 63 and the base 1. The length direction of the first elongated through hole is parallel to the edge of the base 1 where the lead screw support 412 is located. A threaded hole is provided on the base 1 at a position corresponding to the first elongated through hole. A screw is passed through the first elongated through hole and threadedly connected to the threaded hole, thus fixing the first mounting plate 63. The first elongated through hole allows for convenient adjustment of the mounting position of the first mounting plate 63 on the base 1. One end of the indicator ruler 62 is fixed to the second mounting plate 64, and the other end extends outward. In this embodiment, a threaded hole is provided at one end of the indicator ruler 62, and a second elongated through hole is provided on the second mounting plate 64. The length direction of the second elongated through hole is vertical. A bolt is passed through the threaded hole on the indicator ruler 62 and the second elongated through hole on the second mounting plate 64 to connect the indicator ruler 62 to the second mounting plate 64. The second elongated through hole allows for easy adjustment of the vertical mounting position of the indicator ruler 62 on the second mounting plate 64, thereby adjusting the vertical position of the indicator ruler 62 relative to the scale ruler 61 to achieve calibration of the indicator component 6. The second mounting plate 64 is fixed to the edge of the workbench 3, and the indicator ruler 62 is positioned horizontally on one side of the scale ruler 61 to indicate the scale on the scale ruler 61. In this embodiment, a third elongated through hole is provided at the connection between the second mounting plate 64 and the workbench 3. The length direction of the third elongated through hole is the same as that of the first elongated through hole. A threaded hole is provided on the workbench 3 at the position corresponding to the third elongated through hole. A screw is passed through the through hole and threadedly connected to the threaded hole to fix the second mounting plate 64. The third elongated through hole can facilitate the adjustment of the installation position of the second mounting plate 64 on the workbench 3, thereby adjusting the position of the second mounting plate 64 relative to the first mounting plate 63, so that the indicator 62 points to the side of the scale 61.

[0068] Preferably, such as Figure 1 and Figure 7 As shown, the height adjustment mechanism also includes a leveling component 7, which is installed on the base 1 to achieve horizontal adjustment of the base 1, further improving the adjustment accuracy of the height adjustment mechanism.

[0069] Specifically, the base 1 includes a lower base 11 and an upper base 12.
