Description

Technical Field

[0001] This utility model relates to the field of spindle box machining tooling, and more particularly to a spindle box machining tooling. Background Technology

[0002] The existing spindle box requires high machining accuracy; during machining, the mounting plane of the spindle box needs to be within 0.008mm. This high precision requirement means that relying solely on operators to manually correct the mounting plane and actual mounting angle of the spindle box each time during machining is time-consuming, and manual calibration results in significant reading errors and a high defect rate during production.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome at least one of the shortcomings of the prior art and to provide an object conveying device.

[0005] To achieve the above objectives, this utility model proposes a spindle box machining fixture, which includes:

[0006] A spindle box machining fixture, characterized in that it comprises:

[0007] The clamping part has a support surface for supporting the spindle box, the spindle box having at least one surface to be machined;

[0008] A fixing part is provided on the side away from the clamping part for supporting the worktable of the processing machine. The surface to be processed is configured to allow the processing tool to be fed in a direction pointing towards the worktable and / or in a direction pointing towards a plane perpendicular to the worktable.

[0009] A first positioning component is disposed on the clamping portion and includes at least two first limiting portions spaced apart in a first direction. The first limiting portions are configured to contact two opposing first surfaces of the spindle box in the first direction to limit the position of the spindle box in the first direction.

[0010] A second positioning component is disposed on the clamping portion and includes at least two second limiting portions in a second direction perpendicular to the first direction. The second limiting portions are configured to contact two opposing second surfaces of the spindle box in the second direction to limit the position of the spindle box in the second direction.

[0011] Preferably, the first limiting portion is configured as a protrusion extending from the support surface toward the spindle box, the two protrusions in the first direction having two opposing first surfaces extending along a second direction; the spindle box has at least two recesses that are adapted to the protrusions.

[0012] Preferably, the spindle box is configured as an elongated shape extending in a first direction.

[0013] Preferably, the spindle box has two sides in a second direction, the two sides are parallel to each other and both are perpendicular to the support surface; the second limiting assembly includes multiple sets of second-direction limiting components, the second-direction limiting components include two protrusions arranged at intervals, the two protrusions include the two second surfaces, the two second surfaces respectively abut against the two sides.

[0014] Preferably, the two second surfaces are arranged at a distance in the second direction.

[0015] Preferably, the third-direction limiting components are arranged at intervals in the second direction.

[0016] Preferably, the first positioning component is located between the two protrusions.

[0017] Preferably, the second surface is configured to allow the spindle box to be mounted on the machining fixture in a direction pointing toward the support surface.

[0022] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0023] In one of the above solutions, the spindle box is supported in the machining position by a clamping part. The first positioning component restricts the position and movement of the spindle box in the first direction, and the second positioning component restricts the position and movement of the spindle box in the second direction. The first and second limiting components can restrict the movement of the spindle box in the second and second directions when the second machining surface on the spindle box is being machined. This results in high machining accuracy. At the same time, the cooperation of the first and second positioning components reduces the time spent manually verifying the spindle box relative to the machining fixture in the first and second directions, thereby reducing the overall machining error value and improving the machining efficiency and dimensional stability of batch processing.

For example, A being behind B includes A being diagonally behind B.

[0036] The following will be combined with the appendix Figure 1 To be continued Figure 3 The technical solutions in the embodiments are described clearly and completely.

[0037] Combination Figures 1-3 The present invention provides a spindle box 4 machining fixture for loading onto a machining machine table, a rotary worktable 1 of the machining machine table and a worktable surface on the rotary worktable 1, and the machining fixture is installed on the worktable surface.

[0038] refer to Figure 2 The machining fixture includes a fixing part 2 and a clamping part 3, which are detachably connected. The bottom surface of the fixing part 2 is parallel to the loading surface, and when the machining fixture is fixed on the rotary table 1, the bottom surface of the fixing part 2 is in close contact with the table surface. The fixing part 2 extends a certain height away from the table surface, forming two opposing wings 23. The two wings 23 are used for clamping, so that the machining fixture is in close contact with the table surface and fixed thereon. The machining fixture also includes a clearance part 22 extending away from the table surface from the two wings 23. The two sides of the clearance part 22 are recessed towards the middle of the two wings 23. The clearance part 22 has... Positioning end face 21, positioning end face 21 in At the end of the clearance portion 22 away from the wing portion 23, the upper side of the positioning end face 21 is used to support the clamping portion 3. The clamping portion 3 has a support surface 31, which is used to fit tightly against the bottom surface of the spindle box 4. In other embodiments, the fixing portion 2 and the clamping portion 3 may be constructed as an integral structure.

[0039] The spindle box 4 is constructed in an elongated shape, extending along a first direction X in its length direction and along a second direction Y in its width direction, with the first and second directions X and Y perpendicular to each other. The spindle box 4 includes a first surface to be machined and a second surface to be machined. The first surface to be machined is positioned away from the bottom surface of the spindle box 4, and the second surface to be machined is positioned perpendicular to the first direction X and / or the second direction Y. The first surface to be machined is used to feed a machining tool in a direction pointing towards the worktable surface to machine a first shape, and the second surface to be machined is used to feed a machining tool along the first direction X and / or the second direction Y to machine a second shape. Exemplarily, both the first and second shapes have machining positions near their ends along the length direction of the spindle box 4. Therefore, based on the arrangement of these machining positions, the spindle box 4 requires high installation accuracy in its length direction (first direction X).

[0040] For example, the first shape and / or the second shape is a curved surface, one or more hole shapes, one or more threaded hole shapes, a plane or arc surface, etc.

[0041] For example, the first shape and / or the second shape is a curved surface that extends along the length of the spindle box 4. The first shape and / or the second shape is a hole, which is arranged at intervals along the length of the spindle box 4.

[0042] A first positioning component is disposed on the clamping part 3 and includes at least two first limiting parts spaced apart in a first direction X. The first limiting parts are configured to contact two opposing first surfaces of the spindle box 4 in the first direction X to limit the position of the spindle box 4 in the first direction X. A second positioning component is disposed on the clamping part 3 and includes at least two second limiting parts in a second direction Y perpendicular to the first direction X. The second limiting parts are configured to contact two opposing second surfaces in the second direction Y to limit the position of the spindle box 4 in the second direction Y. By limiting the spindle box 4 in the first and second directions Y during the processing of the first and second shapes, the movement of the spindle box 4 in the first and second directions Y is prevented, ensuring processing accuracy. At the same time, the two sets of positioning components allow the spindle box 4 to be directly positioned by the machining fixture when it is loaded, improving loading accuracy and reducing the time spent manually verifying the spindle box 4 relative to the machining fixture in the first and second directions Y. This also reduces the overall processing error value and improves the processing efficiency and dimensional stability of batch processing.

[0043] refer to Figure 3The first positioning component includes at least two protrusions 32, each having two opposing first surfaces extending along a second direction Y; the spindle box 4 has at least two recesses 41 adapted to the protrusions 32. By using surface positioning, the swaying of the spindle box 4 along the direction intersecting the second direction Y during installation is limited, increasing installation accuracy and avoiding verification in that direction during installation.

[0044] The spindle box 4 has two side surfaces 42 in the second direction Y, which are parallel to each other and both perpendicular to the support surface 31. The second limiting portion includes multiple sets of second-direction limiting components, each including two spaced-apart protrusions 33. Each protrusion 33 includes two second surfaces, which abut against the two side surfaces 42 respectively. The two second surfaces are spaced apart in the second direction. The second-direction limiting components are spaced apart in the second direction Y. The first positioning component is located between the two protrusions 33. The second surfaces are configured to allow the spindle box 4 to move in the direction pointing towards the support surface 31 and are mounted on the machining fixture. The protrusions 32 of the first positioning component are configured as rectangular and / or square protrusions 32, and the protrusions 33 of the second positioning component are configured as rectangular and / or square protrusions 33, such that the first positioning component and the second positioning component abut against the spindle box 4 in a surface contact manner. By configuring the first and second positioning components, the calibration time of the spindle box 4 in the first direction X and the second direction Y is reduced. Simultaneously, by clamping the spindle box 4 in the middle in the second direction Y, the degree of freedom of the spindle box 4 in other directions is reduced. Furthermore, the positional error of different spindle boxes 4 mounted on the machining fixture is increased, improving the dimensional stability during batch processing. In other embodiments, the second-direction limiting component is a protrusion (not shown), which includes two second surfaces in the second direction Y. The spindle box has a recessed structure, which includes two side surfaces in the second direction. The two second surfaces abut against these two side surfaces to limit the position of the spindle box in the second direction.

[0045] In one exemplary embodiment, the height of the second positioning component protrusion 33 along the first direction X is greater than the height of the first positioning component protrusion 32. This design avoids the situation where, due to the relatively large distance between the external second positioning component and the spindle box 4, the dimensional error of the spindle box 4 is too large. This would prevent the middle first positioning component from contacting the spindle box 4 first during installation, making it difficult to adjust the position of the spindle box 4 when the second positioning component is in contact with it, thus hindering loading. By ensuring that the height of the second positioning component protrusion 33 is higher than the height of the inner first positioning component protrusion 32, the spindle box 4 can be adjusted at the angle by the external second positioning component first, and then positioned by the middle first positioning component during loading, improving loading convenience.

[0046] In one exemplary embodiment, the flatness of the support surface 31 is no greater than 0.005 mm. This ensures that the machining accuracy of the first and second surfaces to be machined can reach 0.008 mm.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
