Technical Field

[0001] The utility model relates to the technical field of precision machining, in particular to a precision machining tooling with adjustable angle. Background Technique

[0002] Precision machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. Most of the workpieces processed by casting, forging and welding are rough blanks of parts, which generally cannot be directly used on the machine and need further processing to meet the technical requirements of the parts. It is necessary to cut and drill the rough blank of the mechanical workpiece according to the required size, shape and form.

[0003] Currently, for the workpiece processing method, usually the workpiece is placed on the processing table, and the angle of the workpiece on the processing table is fixed. When different-angle processing needs to be realized, it is necessary to manually flip the workpiece or adjust its angle. However, manually adjusting the angle of the workpiece easily leads to instability of the processing accuracy. Even if the operator adjusts the angle as precisely as possible, it is difficult to avoid angle errors caused by human factors or equipment limitations, especially in the case of high-precision processing requirements, which may have a negative impact on the product quality. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a precision machining tooling with adjustable angle, which solves the problem that when the angle of the workpiece on the processing table is fixed and different-angle processing needs to be realized, it is necessary to manually flip the workpiece or adjust its angle.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a precision machining tooling with adjustable angle, including an operation table, at least two support seats, at least two rotating shafts, a frame and a fixing component;

[0009] Further, the two rotating shafts are in the same Y-axis direction.

[0010] Further, the fixing component includes two connecting shafts;

[0011] The two connecting shafts are rotatably connected to the front and rear sides of the inner wall of the frame respectively, and a bearing frame is installed between the opposite ends of the two connecting shafts so that the bearing frame can rotate on the ZY plane;

[0012] Two screws are rotatably connected between the front and rear sides of the inner wall of the bearing frame. The two screws are symmetrically distributed on the left and right sides. Two movable plates are threadedly connected to the outer sides of the screws. Clamps are installed on opposite sides of the two movable plates.

[0013] Furthermore, the outer surface of the screw is provided with two thread grooves, and the thread directions of the two thread grooves are opposite;

[0014] A rotating member is sleeved on the middle section of the outer surface of the screw rod to drive the screw rod to rotate so that the two moving plates move towards or away from each other.

[0015] Furthermore, a rotating motor is mounted on the frame, the output end of which is drivingly connected to one of the connecting shafts, so as to drive the connecting shaft and the supporting plate to rotate on the ZY plane.

[0016] Furthermore, the cross section of the upper end of the card plate is V-shaped.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 , a precision machining tool with adjustable angle in this embodiment, which is used to adjust the angle during workpiece machining to achieve machining at different angles.

[0026] Specifically, it includes an operating table 1, at least two support bases 2, at least two rotating shafts 3, a frame 4, and a fixing component 5; at least two support bases 2 are symmetrically installed on the operating table 1 from left to right, at least two rotating shafts 3 are respectively rotatably connected inside at least two support bases 2, and the frame 4 is arranged between the two rotating shafts 3 so that the frame 4 can rotate on the ZX plane; the fixing component 5 is arranged inside the frame 4 for fixing the workpiece; a driving structure is arranged on one of the support bases 2, and the driving structure is in transmission connection with one of the rotating shafts 3.

[0027] During actual use, the workpiece is placed inside the fixing component 5, and the workpiece is fixed by the fixing component 5. According to the processing requirements, the frame 4 can be rotated forward and backward or the fixing component 5 can be rotated left and right to adjust the angle of the workpiece, so as to achieve machining of the workpiece at different angles.

[0028] It should be noted that the two rotating shafts 3 are located in the same Y-axis direction, and the driving structure includes a driving motor 301, a driving gear 302, and a driven gear 303; the driving motor 301 is arranged on one of the support bases 2, the driving gear 302 is sleeved on the output end of the driving motor 301, the driven gear 303 is sleeved on the outside of one of the rotating shafts 3, and the driven gear 303 is in transmission connection with the driving gear 302.

[0029] In actual use, the output end of the driving motor 301 is rotated to drive the driving gear 302 connected thereto to rotate, and the driving gear 302 and the driven gear 303 are transmitted, that is, when the driving gear 302 rotates, the driven gear 303 and the rotating shaft 3 are driven to rotate, and then the frame 4 is driven to rotate on the ZX plane, so as to adjust the angle of the workpiece.

[0030] See also Figure 2 In order to facilitate the fixation of the workpiece, the fixing assembly 5 in this embodiment includes two connecting shafts 501; the two connecting shafts 501 are rotatably connected to the front and rear sides of the inner wall of the frame 4 respectively, and a supporting frame 502 is installed between the opposite ends of the two connecting shafts 501, so that the supporting frame 502 can rotate on the ZY plane; two screws 503 are rotatably connected between the front and rear sides of the inner wall of the supporting frame 502, and the two screws 503 are symmetrically distributed on the left and right, and two movable plates 504 are threadedly connected to the outer sides of the screws 503, and clamping plates 505 are installed on the opposite sides of the two movable plates 504.

[0031] In actual use, the workpiece is placed between the two clamping plates 505, and the two movable plates 504 are moved toward each other by rotating the screw 503, which simultaneously drives the two clamping plates 505 to move toward each other, so that the two clamping plates 505 are both attached to the outside of the workpiece, thereby fixing the workpiece.

[0032] It should be noted that in order to ensure that the two movable plates 504 can move towards or away from each other when the screw 503 is rotated, two sections of thread grooves are provided on the outer surface of the screw 503 in this embodiment, and the thread directions of the two thread grooves are opposite; a rotating member 506 is sleeved on the middle section of the outer surface of the screw 503 to drive the screw 503 to rotate, so that the two movable plates 504 move towards or away from each other.

[0033] In actual configuration, since the outer surface of the screw 503 is provided with two sections of thread grooves, and the thread directions of these thread grooves are opposite, when the screw 503 rotates, the two moving plates 504 can move in opposite directions or opposite directions. This design effectively realizes the function of two-way movement, improves the flexibility and applicability of the system, and by sleeve-arranging the rotating member 506 on the middle section of the outer surface of the screw 503 to drive the screw 503 to rotate, the driving force can be concentrated in the middle section, which helps to stabilize and balance the rotation process.

[0034] Specifically, in order to ensure that the workpiece can rotate left and right, so as to adjust the angle of the workpiece on the ZY plane, a rotating motor 507 is installed on the frame 4, whose output end is transmission-connected to one of the connecting shafts 501, so as to drive the connecting shaft 501 and the supporting frame 502 to rotate on the ZY plane.

[0035] During actual use, the output end of the rotating motor 507 rotates to drive the connecting shaft 501 in transmission connection therewith to rotate, thereby driving the bearing frame 502 and the workpiece fixed inside it to rotate in the ZY plane, so as to adjust the angle of the workpiece in the ZY plane.

[0036] During actual setting, in order to adapt to the shape of the workpiece, the cross-sectional shape of the upper end of the clamping plate 505 in this embodiment is V-shaped.
