[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-6 A deformation-resistant fixing fixture for a primary gear shaft during lathe cutting includes a lathe 1, a housing 3 fixedly mounted on the upper side of the lathe 1, a primary gear shaft 4 disposed on the side of the housing 3, and a stabilizing fixture assembly 5 sleeved on the outer wall of the primary gear shaft 4; the stabilizing fixture assembly 5 includes an outer structural cylinder 51, support rods 52 fixedly mounted on both sides of the outer structural cylinder 51, a dovetail groove 54 disposed on the lower side of the support rods 52, an end plate 55 fixedly mounted at the end of the dovetail groove 54, an electric telescopic rod 56 fixedly mounted between the end plate 55 and the support rods 52, a middle support cylinder 57 disposed on the inner side of the outer structural cylinder 51, a plurality of pressure sensors 510 fixedly connected between the middle support cylinder 57 and the inner wall of the outer structural cylinder 51, and an inner cylinder 58 rotatably mounted on the inner side of the middle support cylinder 57, the inner cylinder 58 being slidably sleeved on the outer wall of the primary gear shaft 4.

[0025] With the above-described configuration, the pressure sensor 510 can detect the pressure transmission value between the outer cylinder 51 and the middle support cylinder 57. This pressure corresponds to the lateral pressure between the inner cylinder 58 and the outer wall of the first-stage gear shaft 4, thereby indirectly detecting the supporting force provided by the inner cylinder 58 to the first-stage gear shaft 4.

[0026] In this method, a gasket 66 is fixedly installed on the inner side of the clamping block 65.

[0027] By setting the pad 66 as described above, the clamping stability of the workpiece on the inner side of the clamping block 65 is improved.

[0028] In this method, a dovetail block 53 is fixedly installed at the bottom of the support rod 52. The dovetail block 53 is slidably engaged with the inside of the dovetail groove 54. The dovetail groove 54 is screwed onto the upper side of the lathe 1. Several balls 59 are embedded between the intermediate bearing cylinder 57 and the inner cylinder 58.

[0029] With the above-mentioned arrangement, the ball bearing 59 reduces the rotational friction loss between the inner cylinder 58 and the intermediate bearing cylinder 57 when the first-stage gear shaft 4 drives the inner cylinder 58 to rotate.

[0030] In this method, a clamping assembly 6 is provided at the end of the first-stage gear shaft 4. The clamping assembly 6 includes a mounting plate 61, which is screwed onto the end of the first-stage gear shaft 4. A fixing cylinder 62 is fixedly installed on the side of the mounting plate 61. Several recessed bolt holes 63 are opened on the inner side of the fixing cylinder 62. Several hydraulic rods 64 are fixedly installed on the outer wall of the fixing cylinder 62. The output end of the hydraulic rod 64 slides through to the inner side of the fixing cylinder 62, and a clamping block 65 is fixedly installed on the output end of the hydraulic rod 64.

[0031] With the above-described configuration, the hydraulic rod 64 is activated to move the clamping block 65 on its inner side toward the center position of the fixed cylinder 62, thereby clamping the workpiece at the center point inside the fixed cylinder 62.

[0032] In this configuration, a drive motor 11 is fixedly installed inside the chassis 3, a second gear 12 is fixedly installed on the output end of the drive motor 11, a first gear 10 is fixedly installed at the rear end of the first gear shaft 4, the first gear 10 meshes with the second gear 12, and the first gear shaft 4 rotates through to the outside of the chassis 3.

[0033] With the above configuration, when the drive motor 11 is started, it drives the second gear 12 to rotate. The second gear 12 drives the first gear shaft 4 to rotate through meshing with the first gear 10, so as to fix the workpiece held inside the cylinder 62 to perform rotational cutting.

[0034] In this method, a controller 2 is fixedly installed on the lathe 1, and a heat dissipation hole 31 is provided on the rear side of the machine box 3.

[0035] With the above-described configuration, the heat dissipation hole 31 provides heat dissipation for the drive motor 11 inside the chassis 3.

[0036] In this method, a support side plate 7 is fixedly installed on the side of the lathe 1, an electric push rod 8 is fixedly installed on the side of the support side plate 7, and a turning head 9 is fixedly installed on the output end of the electric push rod 8.

[0037] With the above setup, the electric push rod 8 is activated to drive the turning head 9 to drive the workpiece fixed inside the fixed cylinder 62. The rotating workpiece comes into contact with the turning head 9 and performs cutting action.

[0038] The working principle of the anti-deformation fixing fixture for a primary gear shaft during lathe cutting provided by this utility model is as follows:

[0039] In use, the workpiece to be cut is placed inside the fixed cylinder 62, and its position is adjusted so that it is approximately at the center of the fixed cylinder 62. The hydraulic rod 64 is activated, and its output end drives the clamping block 65 to move towards the center of the fixed cylinder 62. Since a shim 66 is fixed inside the clamping block 65, the shim 66 increases the friction between the shim and the workpiece, thereby stably clamping the workpiece at the center point inside the fixed cylinder 62. The drive motor 11 inside the machine housing 3 is activated by the controller 2, and its output end drives the second gear 12 to rotate. The second gear 12, through meshing with the first gear 10, drives the first-stage gear shaft 4 to rotate. This causes the workpiece held inside the fixed cylinder 62 to begin rotating, synchronously driving the electric push rod 8 to move the turning head 9 closer to the workpiece for cutting. While the first-stage gear shaft 4 drives the workpiece to rotate, the stabilizing fixture assembly 5 begins to function. If the pressure sensor at the front end of the first-stage gear shaft 4 detects a large value, it indicates that the support provided by the inner cylinder 58 needs to move closer to the front. After receiving the signal from the pressure sensor 510, the controller 2 controls the electric telescopic rod 56 to retract, adjusting the position of the outer cylinder 51 until the pressure sensor values ​​on the front and rear sides of the inner side of the outer cylinder 51 are similar. At this point, the inner cylinder 58 can provide stable support for the first-stage gear shaft 4.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
