Description

Technical Field

[0001] The utility model belongs to the technical field of rotary wheel brackets, and particularly relates to a deflection angle adjusting mechanism for a rotary wheel bracket. Background Art

[0002] Generally, the function of a rotary wheel bracket is only to support and rotate a cylindrical workpiece, and then cooperate with other equipment to process and produce the workpiece. For example, welding, surface treatment, etc.

[0003] However, the equipment for different processes is different. For example, the welding machine in the welding process can generally move back and forth along the track to realize the welding of the workpiece. However, for example, the shot blasting machine for surface treatment cannot move, and can only push the workpiece to move and let the workpiece pass through the shot blasting machine to realize surface treatment.

[0004] The prior art generally sets equipment such as a hydraulic ejector rod at one end of the workpiece to achieve the purpose of pushing the workpiece. However, it is found after actual use that this method requires additional use of equipment such as a hydraulic ejector rod, which not only occupies a large area and has high power consumption, but also generates axial friction between the workpiece and the rotary wheel during the axial movement of the workpiece, easily damaging the rotary wheel. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a deflection angle adjusting mechanism for a rotary wheel bracket, which is used to solve the technical problems in the prior art that the rotary wheel bracket can only support and rotate a cylindrical workpiece, cannot axially move the cylindrical workpiece, and needs to use equipment such as a hydraulic ejector rod, resulting in a large floor area, high power consumption, and easy damage to the rotary wheel.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: A deflection angle adjusting mechanism for a rotary wheel bracket, comprising:

[0007] A rotary wheel fixing box, which is movably arranged on a base;

[0008] A fixing plate, which is arranged on the top surface of the rotary wheel fixing box;

[0009] A movable plate, which is stacked on the fixing plate, the centers of the movable plate and the fixing plate coincide, and the movable plate rotates around the center of the fixing plate; a rotary wheel bracket is further arranged on the top surface of the movable plate.

[0010] By adjusting the movable plate, the utility model can deflect the rotary wheel frame, that is, the central axis of the rotary wheel intersects with the axis of the cylindrical workpiece it supports, rather than being parallel; when the rotary wheel is driven by an external power source, the frictional force generated between the rotary wheel and the cylindrical workpiece during rotation is oblique, and this frictional force is the resultant force of the axial frictional force and the radial frictional force. Therefore, the axial frictional force can push the cylindrical workpiece to achieve axial displacement, and the radial frictional force drives the cylindrical workpiece to rotate. In addition, the deflection angle of the rotary wheel is also related to the distance that the cylindrical workpiece is pushed out after the rotary wheel rotates one circle. The contact trajectory between the rotary wheel and the cylindrical workpiece is spiral. The larger the deflection angle of the rotary wheel, the greater the distance that the rotary wheel pushes the cylindrical workpiece in one circle.

[0011] Further: convex ear plates are provided on the same side of the movable plate and the fixed plate, and fixed shafts are provided on the ear plates;

[0012] A tractor, and both ends of the tractor are respectively connected to the fixed shafts.

[0013] Beneficial effect of this step: By connecting two fixed shafts through the tractor and adjusting the length of the tractor, the relative rotation of the movable plate and the fixed plate can be driven, and the angle between the movable plate and the fixed plate can be adjusted.

[0014] Further: the tractor includes:

[0015] Two lifting lugs, one end of the lifting lug is a ring, and the other end is a stud. The ring is sleeved on the fixed shaft, and the studs of the two lifting lugs have opposite helix directions;

[0016] A sleeve, both ends of the sleeve are provided with internal threaded holes, and the two internal threaded holes are respectively adapted to the two lifting lugs;

[0017] A wrenching surface or a wrenching tool is provided in the middle of the sleeve.

[0018] Beneficial effect of this step: Equivalent to the working principle of a turnbuckle, by rotating the sleeve forward or backward, the two lifting lugs can be made to approach or move away from each other.

[0019] Further: the wrenching tool includes:

[0020] A gear, which is fixedly sleeved in the middle of the sleeve;

[0021] A handle, one end of the handle is movably sleeved on the sleeve, and movable fork-shaped levers are provided on the front and back of the handle, and the positions of the fork-shaped levers correspond to the position of the gear.

[0022] Beneficial effect of this step: By adjusting the position of the fork-shaped lever and pressing or lifting the handle, the forward and reverse rotation of the sleeve can be achieved, which is more convenient and fast.

[0023] Further: An arc-shaped scale is provided on the fixed plate, and a marking arrow is provided in the middle of one side of the movable plate corresponding to the scale.

[0024] Beneficial effect of this step: The specific deflection angle of the movable plate is displayed through the marking arrow and the scale.

[0025] Further: A polytetrafluoroethylene plate is also provided between the movable plate and the fixed plate.

[0026] Beneficial effect of this step: The polytetrafluoroethylene plate has the effects of lubrication and drag reduction.

[0027] Further: A threaded rotating shaft or a threaded hole is provided at the center of the fixed plate;

[0028] When the center of the fixed plate is a threaded rotating shaft, the threaded rotating shaft is equipped with a locking nut;

[0029] When the center of the fixed plate is a threaded hole, the threaded hole is equipped with a locking bolt.

[0030] Beneficial effect of this step: After the movable plate is adjusted to the set deflection angle, the movable plate and the fixed plate are locked to further strengthen the fixing effect.

[0031] Further: The rotating wheel on the rotating wheel frame is frustum-shaped.

[0032] Beneficial effect of this step: When the rotating wheel deflects, the frustum-shaped rotating wheel has a larger contact area with the cylindrical workpiece.

[0033] The beneficial effects of the present utility model are:

[0034] By using the movable plate and the fixed plate to change the axis of the rotating wheel, making the rotating wheel deflect, thereby changing the direction of the frictional force between the rotating wheel and the cylindrical workpiece. When there is an external driving source for the rotating wheel, it can push the cylindrical workpiece to generate an axial displacement, replacing equipment such as hydraulic jacks in the prior art, so as to achieve the effects of saving space, reducing energy consumption, and saving costs.

[0056] Embodiment

[0057] As Figures 1 to 4 and Figure 10 shown, a deflection angle adjusting mechanism of a rotating wheel bracket provided by this utility model includes:

[0058] Rotating wheel fixing box 1, the rotating wheel fixing box 1 is movably arranged on the base. Generally, there are two relatively arranged rotating wheel fixing boxes 1 on the base;

[0059] Fixing plate 2, the fixing plate 2 is arranged on the top surface of the rotating wheel fixing box 1;

[0060] Movable plate 3, the movable plate 3 is stacked on the fixing plate 2, the centers of the movable plate 3 and the fixing plate 2 coincide, and the movable plate 3 rotates around the center of the fixing plate 2; a rotating wheel frame 4 is further arranged on the top surface of the movable plate 3, and a rotating wheel 41 is arranged on the rotating wheel frame 4.

[0061] By adjusting the movable plate 3 of the present utility model, the rotating wheel frame 4 can be deflected, that is, the central axis of the rotating wheel 41 and the axis of the cylindrical workpiece 10 it supports become intersecting instead of parallel; when the rotating wheel 41 is driven by an external power source, the frictional force generated between the rotating wheel 41 and the cylindrical workpiece 10 during rotation is oblique, and this frictional force is the resultant force of the axial frictional force and the radial frictional force. Therefore, the axial frictional force can push the cylindrical workpiece 10 to achieve axial displacement, and the radial frictional force drives the cylindrical workpiece 10 to rotate. In addition, the deflection angle of the rotating wheel 41 is also related to the distance that the cylindrical workpiece 10 is pushed out after the rotating wheel 41 rotates one circle. The contact trajectory between the rotating wheel 41 and the cylindrical workpiece 10 is spiral. The larger the deflection angle of the rotating wheel 41, the greater the distance that the rotating wheel 41 pushes the cylindrical workpiece 10 to move in a single circle.

[0062] On the basis of the above technical solution, protruding ear plates 5 are arranged on the same side of the movable plate 3 and the fixing plate 2, and a fixed shaft 6 is arranged on the ear plate 5;

[0063] Tractor 7, both ends of the tractor 7 are respectively connected to the fixed shaft 6.

[0064] By connecting the two fixed shafts 6 through the tractor 7 and adjusting the length of the tractor 7, the relative rotation of the movable plate 3 and the fixing plate 2 can be driven, and the angle between the movable plate 3 and the fixing plate 2 can be adjusted.

[0065] As Figure 5 shown, the tractor 7 includes:

[0066] Two lifting lugs 71, one end of the lifting lug 71 is a ring, and the other end is a stud. The ring is sleeved on the fixed shaft 6, and the studs of the two lifting lugs 71 have opposite helix directions;

[0067] A sleeve 72, both ends of the sleeve 72 are provided with internal threaded holes, and the two internal threaded holes are respectively adapted to the two lifting lugs 71;

[0068] A wrenching surface 721 or a wrenching tool is provided in the middle of the sleeve 72, and the wrenching surface 721 is for tools such as wrenches to fit and wrench.

[0069] In this embodiment, the working principle of the tractor 7 is the same as that of the turnbuckle. By rotating the sleeve 72 forward or backward, the two lifting lugs 71 can move closer or farther away simultaneously, that is, it plays a role in pulling the movable plate 3 closer or farther away.

[0070] As Figure 6 shown, the wrenching tool includes:

[0071] A gear 73, which is fixedly sleeved in the middle of the sleeve 72;

[0072] A handle 74, one end of which is movably sleeved on the sleeve 72, and movable fork 75s are provided on both the front and back of the handle 74, and the positions of the fork 75s correspond to the position of the gear 73.

[0073] By adjusting the position of the fork, the fork 75 on the front or back is engaged into the gear 73, and then the handle 74 is pressed or lifted to realize the forward and reverse rotation of the sleeve 72, which is more convenient, faster and labor-saving, and no additional tool is required.

[0074] As Figure 7 and Figure 8 shown, an arc-shaped scale 8 is provided on the fixed plate 2, and a marking arrow 9 is provided in the middle of one side of the movable plate 3 corresponding to the scale 8.

[0075] The specific deflection angle of the movable plate 3 is displayed by the marking arrow 9 and the scale 8.

[0076] On the basis of the above technical solution, a polytetrafluoroethylene plate is further provided between the movable plate 3 and the fixed plate 2.

[0077] The polytetrafluoroethylene plate has the effects of lubrication and resistance reduction.

[0078] As Figure 4 and Figure 9 shown, a threaded rotating shaft or a threaded hole is provided at the center of the fixed plate 2;

[0079] When the center of the fixed plate 2 is a threaded rotating shaft, the threaded rotating shaft is equipped with a locking nut;

[0080] When the center of the fixed plate 2 is a threaded hole, the threaded hole is equipped with a locking bolt 21.

[0081] After the movable plate 3 is adjusted to the set deflection angle, the movable plate 3 is locked with the fixed plate 2 to further enhance the fixing effect.

[0082] AsFigure 9 and Figure 10 As shown in Figure 10 , the rotating wheel 41 on the rotating wheel frame 4 is frustum-shaped.

[0083] When the rotating wheel 41 deflects, the frustum-shaped rotating wheel 41 has a larger contact area with the cylindrical workpiece 10.

[0084] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
