Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling for a slant plate base milling machine. Background Technology

[0002] In existing technologies, the swashplate base, as a key component in continuously variable transmissions (CVTs), requires stringent precision in its machining. The swashplate base is a non-circular structure, and there are positional tolerance requirements between the semi-circular hole and the end face pin hole (relative to the inner hole datum, the positional tolerance is within φ0.03mm according to the maximum material condition principle). Due to the high requirements for form and position tolerances, the difficulty in aligning the semi-circular datum on a four-axis rotary table, and the fact that only one swashplate base can be machined at a time, requiring repositioning and alignment each time, production efficiency is low, and significant time and labor costs are incurred.

[0003] Therefore, it is necessary to provide a swashplate base milling machine fixture to overcome the defects mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a slant plate base milling machine fixture.

[0005] According to one aspect of the present invention, a swashplate base milling machine fixture is provided, which is mounted on a milling machine and can simultaneously assemble multiple swashplate bases for machining, including:

[0006] The support body includes a first support and a second support coaxially arranged. The first support and the second support have the same shape. The first support includes a chuck section at the end, an assembly section extending axially from the chuck section, and a clearance section extending axially from the assembly section. The assembly section has symmetrically opened mounting grooves that extend radially along the assembly section. The clearance section of the first support is connected to the chuck section of the second support. The first support and the second support are integrally formed.

[0007] A support member is provided in a mounting groove for fixing the swashplate base.

[0008] Preferably, the diameter of the chuck section is larger than the diameter of the assembly section, and the diameter of the assembly section is larger than the diameter of the clearance section.

[0009] Preferably, the assembly section is provided with a cut surface, which is located on both radial sides of the assembly section and cuts into the chuck section along the axial direction of the support body. The cut surface passes vertically through the mounting groove and is located at the middle position in the length direction of the mounting groove.

[0010] Preferably, the support includes a fixing plate fixed to the assembly section and an assembly plate for fixing the swashplate base. The assembly plate extends from both ends of the fixing plate toward the side opposite to the assembly section and is arranged perpendicular to the fixing plate.

[0011] Preferably, the fixing plate has a waist-shaped groove on the side opposite to the assembly section, and bolt through holes are spaced apart in the waist-shaped groove.

[0012] Preferably, the assembly plate is provided with bolt through holes at intervals.

[0013] Preferably, the outer end face of the avoidance section of the second support column is provided with a stepped blind hole, which is used to cooperate with the milling machine positioning and clamping structure to provide positioning support for the swashplate base milling machine tooling.

[0014] Preferably, the stepped blind hole is located at the center of the outer end face of the avoidance section of the second support.

[0015] Compared with the prior art, the slant plate base milling machine fixture provided by this utility model has the following beneficial effects:

[0016] Due to the adoption of the above technical solution, this utility model has the advantages of simple structure, ingenious design and low cost. The slant plate base milling machine fixture can install 4 slant plate bases at one time. After aligning the center of the fixture, it is clamped on the milling machine. The position of the step blind hole on the end face of the fixture is the center. The 4 slant plate bases are processed in sequence. The 4 slant plate bases do not need to be repeatedly positioned and aligned with the rotation center, thereby improving production efficiency, reducing the parts transfer cycle and saving time and labor costs.

[0030] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0031] See Figure 1 and Figure 4 This embodiment discloses a milling machine fixture for swashplate base 10, which can install four swashplate bases 10 at a time. The fixture is positioned and installed on a milling machine, allowing for sequential machining of the four swashplate bases 10.

[0032] The swashplate base 10 is composed of a support body 1 and a support member 2. The support body 1 includes a first support 11 and a second support 12 of the same shape. The first support 11 and the second support 12 are coaxially arranged and integrally formed. The first support 11 includes a chuck section 111 located at the end, an assembly section 112 extending axially from the chuck section 111, and a clearance section 113 extending axially from the assembly section 112. The chuck section 111, the assembly section 112, and the clearance section 113 are coaxially arranged. The diameter of the chuck section 111 is larger than the diameter of the assembly section 112, and the diameter of the assembly section 112 is larger than the diameter of the clearance section 113. The clearance section 113 of the first support 11 is connected to the chuck section 111 of the second support 12.

[0033] See Figure 2 and Figure 3 The assembly section 112 has radially symmetrical mounting grooves 1121. The mounting grooves 1121 extend along the diameter of the assembly section 112. A notch surface 1122 is also provided on the assembly end, with the notch surface located on both radial sides of the assembly section 112 and cutting into the chuck section 111 along the axial direction of the support body 1. The notch surface 1122 passes perpendicularly through the mounting groove 1121 and is located at the midpoint of the length of the mounting groove 1121. Therefore, the outer surface of the assembly section 112 consists of a pair of arc surfaces and a pair of flat surfaces. The arc surfaces are used to fit and support the swashplate base 10, while the flat surfaces are used to avoid some structures of the swashplate base 10, preventing interference with the installation of the swashplate base 10.

[0034] The chuck section 111 is used for clamping with the milling machine, and the clearance section 113 is used for the infeed and retraction of the milling cutter.

[0035] See Figure 5 The support member 2 is installed in the mounting groove 1121 to fix the swash plate base 10. The support member 2 includes a fixing plate 21 fixed to the assembly section 112 and an assembly plate 22 for fixing the swash plate base 10. The assembly plate 22 extends from both ends of the fixing plate 21 toward the side opposite to the assembly section 112 and is arranged perpendicular to the fixing plate 21.

[0036] The fixing plate 21 has a waist-shaped groove 211 on the side opposite to the assembly section 112, and a bolt through hole 3 is provided in the waist-shaped groove 211. The waist-shaped groove 211 is used to accommodate the end of the locking bolt 5. The locking bolt 5 passes through the bolt through hole 3 to fix the support 2 to the assembly section 112. The assembly plate 22 is provided with bolt through holes 3 at intervals, so that the locking bolt 5 can pass through and be connected and fixed to the swashplate base 10.

[0037] See Figure 2 A stepped blind hole 4 is provided on the outer end face of the clearance section 113 of the second support column 12. The stepped blind hole 4 is located at the center of the outer end face of the clearance section 113 of the second support column 12. The stepped blind hole 4 is used to cooperate with the milling machine positioning and clamping structure to provide positioning support for the milling machine tooling of the swashplate base 10. The stepped blind hole 4 is located at the center of the end face, which is the rotation center for machining the swashplate base 10.

[0038] See Figure 6 The swashplate base 10 includes arc-shaped openings 101 on opposite sides, recessed grooves 102 on opposite sides, and an upper end face 103 at the top. The upper end face 103 has a through-hole 1031, bolt holes 1032 corresponding to bolt holes 3 on the mounting plate 22, and a pin hole 1033 located between a pair of adjacent bolt holes 3. The bolt holes 1032 and pin holes 1033 are distributed around the periphery of the through-hole 1031.

[0039] The runout of the outer diameter of the tooling was checked using a lever dial indicator. The chuck section 111 of the milling machine tooling for the swashplate base 10 was clamped and fixed using a four-axis rotary table on a milling machine. The stepped hole of the clearance section 113 was supported and limited. The clamping and pushing action achieved the runout of the outer diameter of the swashplate. The swashplate base 10 was installed on the support section, with the arc opening 101 of the swashplate base 10 fitting against the arc surface of the assembly section 112. At this time, the assembly plates 22 on both sides extended into the recessed grooves 102 and had a gap with the swashplate base 10, without contact. Locking bolts 5 were passed through the bolt through holes 3 on the assembly plate 22 and connected to the bolt holes 1032 on the swashplate base 10 to achieve bolt back tension and fixation of the swashplate base 10. After installing the four suction cup bases, the pin holes 1033, the two side corner holes, and the end faces on the upper end faces 103 of the four swashplate bases 10 were milled sequentially using a milling machine. After processing is completed, the swash plate base 10 can be disassembled and a new swash plate base 10 to be processed can be installed. The tooling is not disassembled during this process.

[0040] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
