Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a honing equipment for heavy workpieces that can be lifted and moved. Background Technology

[0002] In the field of machining, honing is generally used for machining the inner holes of workpieces. The transportation and positioning of the workpiece before honing directly affect the honing accuracy, and thus the yield of the workpiece. In the existing technology, for light workpieces, such as those weighing less than 1 ton, a moving device that combines vertical lifting and horizontal movement can be used to move the workpiece in order to achieve accurate transportation and positioning. When using this method to move heavy workpieces (such as workpieces weighing about 10 tons), the load-bearing capacity of the moving device is required to be high, and the moving device is also more prone to damage and reduced accuracy. Therefore, how to design a honing equipment that can be lifted and moved for heavy workpieces is the goal pursued by those skilled in the art. Utility Model Content

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0039] See Figures 1-12 The present invention relates to a honing equipment for heavy workpieces that can be lifted and moved, comprising a climbing device, a worktable 1, and a horizontal moving device. The honing structure in the honing equipment of the present invention can adopt existing technology, which will not be described in detail here.

[0040] The climbing device includes a lower lifting platform 2 located below, an upper lifting platform 3 located above, and a first lead screw drive mechanism located between the upper lifting platform 3 and the lower lifting platform 2.

[0041] The lower lifting platform 2 has a horizontally extending lower surface and an inclined upper surface, while the upper lifting platform 3 has a horizontally extending upper surface 31 and an inclined lower surface. The upper and lower inclined surfaces are parallel and slide relative to each other while maintaining contact. One of the upper and lower lifting platforms 3 and 2 has a first groove 33, and the other has a first slider 23. Specifically, in one embodiment, the upper part of the lower lifting platform 2 is recessed to accommodate a first lead screw drive mechanism and reduce friction between the upper and lower platforms 3 and 2. The lower lifting platform 2 has a first slider 23 on each of its left and right sides; the first slider 23 is a linear slider. The upper platform 3 has multiple downward-facing first grooves 33. By providing an open slide groove, assembly is facilitated. In other embodiments, the first slide groove 33 can also be configured with a central opening. In one embodiment, the number of first slide grooves 33 is two on each side. Of course, in other embodiments, in order to better bear the load, the number of first slide grooves 33 can be adjusted according to the weight of the heavy workpiece 8 being transported. The upper surface of the first slider 23 slides in cooperation with the upper inner wall of the first slide groove 33. The upper surface of the first slider 23 forms an inclined surface on the lower lifting platform, and the upper inner wall of the first slide groove 33 forms a lower inclined surface on the rising platform. In other embodiments, the lower lifting platform 2 can also be configured with an upward-opening first slide groove 33, and the rising platform can be configured with a first slider 23. In this case, the lower inner wall of the first slide groove 33 forms an inclined surface on the lower lifting platform, and the lower surface of the first slider 23 forms a lower inclined surface on the rising platform.

[0042] The first lead screw mechanism is used to drive the lower inclined surface of the lifting platform to slide relative to the upper inclined surface of the lower lifting platform. The first lead screw drive mechanism includes a first lead screw 41, a first nut disposed on the first lead screw 41, a first tension seat 42 fixedly disposed on the lower lifting platform 2, a first fixed seat 43 fixedly disposed on the lower lifting platform 2, and a first motor assembly for driving the first lead screw 41 to rotate.

The axis of the first lead screw 41 is located below the upper inclined surface of the lower lifting platform and the lower inclined surface of the lifting platform, that is, below the upper surface of the first slider 23 and the upper inner wall of the first slide groove 33. Through this arrangement, the upper inclined surface of the lower lifting platform and the lower inclined surface of the lifting platform can better distribute the pressure of the heavy workpiece 8 and reduce the load on the first lead screw drive mechanism.

[0043] The two ends of the first lead screw 41 are located within the first tension seat 42 and the first fixed seat 43. A first nut connecting seat 32 is fixedly installed on the lifting platform 3, and the first nut connecting seat 32 is fixedly connected to the first nut. In one embodiment, the first nut connecting seat 32 and the first nut can be integrally formed. Specifically, the first fixed seat 43 is located on the upper part of the lower lifting platform 2, and the first tension seat 42 is located on the lower part of the lower lifting platform 2. The first fixed seat 43 is provided with two sets of angular contact bearings 631 in the same direction and one set of angular contact bearings 631 in different directions, so that the shaft of the lead screw... Both the axial and radial directions are fixed. The first tension seat 42 is provided with two sets of angular contact bearings 631 in the same direction. The radial positioning of the lead screw is achieved by the allowance between the nut 632 and the spacer 633. The axial tension allowance is set. In summary, by fixing one end and stretching the other end, the rigidity, accuracy and stability of the first lead screw 41 can be improved, the influence of thermal deformation can be reduced, and the accuracy of the honing equipment for heavy workpieces that can be lifted and moved in this utility model can be improved. In one embodiment, the first motor assembly includes a drive motor 44, a reducer 45 and a coupling 46.

[0044] In one embodiment, an anti-collision pad 64 is provided between the first nut and the first tension seat 42, and an anti-collision pad 64 is provided between the first nut and the first fixed seat 43. The anti-collision pad 64 is arranged with a downward opening to facilitate assembly. For the honing equipment of the present invention, which can lift and move heavy workpieces, the lifting platform 3 loaded with heavy workpieces 8 has a large inertia. By providing the anti-collision pad 64, the first nut is prevented from directly impacting the first tension seat 42 or the first fixed seat 43.

[0045] The horizontal moving device includes a base frame 5 and a second lead screw drive mechanism disposed between the base frame 5 and the lower lifting platform 2. The base frame 5 has a horizontally extending upper surface, and the lower lifting platform 2 has a horizontally extending lower surface. The upper surface of the base frame and the lower surface of the lower lifting platform are slidably disposed relative to each other and in contact. The second lead screw mechanism is used to drive the lower surface of the lower lifting platform to slide relative to the upper surface of the base frame. A second sliding groove 24 is provided on one of the lower lifting platform 2 and the base frame 5, and a second slider 51 is provided on the other. Specifically, in one embodiment, the upper part of the base frame is recessed to accommodate the second lead screw drive mechanism, which can also reduce the friction between the lower lifting platform 2 and the base frame 5. A second slider 51 is provided on each of the left and right sides of the base frame 5. The second slider 51 is a linear slider. The lower lifting platform 2 is provided with... There are multiple downward-facing second slide grooves 24. By setting slide grooves with openings, assembly is facilitated. In other embodiments, the second slide grooves 24 can also be set with a central opening. In one embodiment, the number of second slide grooves 24 is three on each side. Of course, in other embodiments, in order to distribute the weight, the number of second slide grooves 24 can be adjusted according to the weight of the heavy workpiece being transported. The upper surface of the second slider 51 slides in cooperation with the upper inner wall of the second slide groove 24. The upper inner wall of the second slide groove 24 forms the lower surface of the lower lifting platform. The upper surface 511 of the second slider forms the upper surface of the base frame. In other embodiments, the base frame 5 can also be set with upward-facing second slide grooves 24, and the lower lifting platform 2 can be set with second sliders 51. In this case, the lower surface of the second slider 51 forms the lower surface of the lower lifting platform.

[0046] The second lead screw drive mechanism includes a second lead screw 61, a second nut mounted on the second lead screw 61, a second tension seat 62 fixedly mounted on the base frame 5, a second fixing seat 63 fixedly mounted on the base frame 5, and a second motor assembly for driving the second lead screw 61 to rotate. The axis of the second lead screw 61 extends horizontally, and the axis of the second lead screw 61, the upper surface of the base frame, and the lower surface of the lower lifting platform are arranged in parallel. The axis of the second lead screw 61 is located below the upper surface of the base frame and the lower surface of the lower lifting platform, that is, below the upper surface of the second slider 51 and the upper inner wall of the second slide groove 24. This arrangement allows the upper surface of the base frame and the lower surface of the lower lifting platform to better distribute the pressure of the heavy workpiece 8, reducing the load on the second lead screw drive mechanism.

[0047] Both ends of the second lead screw 61 are located within the second tension seat 62 and the second fixed seat 63. A second nut connecting seat 25 is fixedly mounted on the lower lifting platform 2, and the second nut connecting seat 25 is fixedly connected to the second nut. In one embodiment, the second nut connecting seat 25 and the second nut can be integrally formed. Specifically, the second fixed seat 63 is located on the rear side of the base frame 5, and the second tension seat 62 is located on the front side of the base frame 5, as shown below. Figure 4As shown, the second fixed seat 63 is equipped with two sets of angular contact bearings 631 in the same direction and one set of angular contact bearings 631 in different directions, so that the lead screw is fixed in both the axial and radial directions. Figure 5 As shown, the second tension seat 62 is provided with two sets of angular contact bearings 631 in the same direction. The radial positioning of the lead screw and the setting of the axial tension allowance are achieved through the allowance between the nut 632 and the spacer 633. In summary, by using the installation method of fixing one end and stretching the other end, the rigidity, accuracy and stability of the second lead screw 61 can be improved, the influence of thermal deformation can be reduced, and the accuracy of the honing equipment for heavy workpieces that can be lifted and moved in this utility model can be improved. In one embodiment, the second motor assembly includes a drive motor 44, a reducer 45 and a coupling 46.

[0048] In one embodiment, an anti-collision pad 64 is provided between the second nut and the second tension seat 62, and an anti-collision pad 64 is provided between the second nut and the second fixed seat 63. The anti-collision pad is open downwards for easy assembly. For the honing equipment of the present invention, which can lift and move heavy workpieces, the inertia of the climbing device carrying heavy workpieces is large. By providing the anti-collision pad 64, the second nut is prevented from directly hitting the second tension seat 62 or the second fixed seat 63.

[0049] The worktable 1 is fixedly installed on the upper surface of the lifting platform. The worktable 1 extends horizontally and is used to place heavy workpieces 8. The worktable 1 is equipped with a positioning structure.

[0050] The positioning structure includes a vertical rod 71, a horizontal rod 72, a screw 73 inserted into the horizontal rod 71, a locking nut 74 cooperating with the screw 73, and a positioning block 75 set on the worktable. A slot 11 is provided on the worktable 1. The lower end of the screw 73 is connected to the slot 11. Specifically, the cross-section of the slot 11 can be set to be wider at the bottom and narrower at the top to limit the vertical movement of the screw 73 and prevent the screw 73 from coming out of the slot 11. One end of the horizontal rod 72 is placed on the upper surface of the vertical rod. Specifically, one end of the horizontal rod 72 is not connected to the upper surface of the vertical rod 71 to facilitate height adjustment of the vertical rod 71, thereby adapting to heavy workpieces 8 of different heights. The other end of the horizontal rod 72 is used to abut against the upper surface of the heavy workpiece 8. When a heavy workpiece 8 is placed on the worktable 1, the horizontal rod 72 is set to extend horizontally or tilted towards the heavy workpiece 8. Specifically, in one embodiment… Four uprights 71 are provided on the workbench 1. The uprights 71 are located at the four corners of the workbench 1 and extend vertically. Their height is set to be equal to or slightly greater than the height of the upper surface of the heavy workpiece 8 and the crossbar 72 that abut against each other. This makes the crossbar 72 more firmly abut against the heavy workpiece 8, preventing the heavy workpiece 8 from shifting during movement and ensuring its transportation and positioning accuracy. The locking nut 74 can lock the screw 73 relative to the crossbar 72 as needed, so that the crossbar 72 is tightly abutted against the heavy workpiece 8. This also prevents the heavy workpiece from shifting during movement and ensures its transportation and positioning accuracy. The positioning block 75 includes two blocks located on the left and rear sides of the workbench 1. When the heavy workpiece 8 is placed in place, it abuts against the two positioning blocks 75 respectively, so that the heavy workpiece 8 is placed in the correct position.

[0051] When using the honing equipment of this utility model that allows for the lifting and moving of heavy workpieces, first place the heavy workpiece 8 on the workbench 1, with two positioning blocks 75 abutting against the left and rear sides of the heavy workpiece 8 respectively. Then, place one end of each of the four crossbars 72 on the heavy workpiece 8, tighten the locking nut 74 to press the crossbars 72 onto the heavy workpiece 8, and start the first lead screw drive mechanism to adjust the heavy workpiece 8 to the required height. This height can be easily calculated by the movement distance of the first nut in the first lead screw drive mechanism, that is, the movement distance of the first nut is equal to twice the movement height of the heavy workpiece 8. Then, start the second lead screw drive mechanism to adjust the heavy workpiece 8 to the required position in the front-back direction.
