[0002] CNC lathe auxiliary tooling refers to non-standard tools or devices designed to assist in workpiece positioning, clamping, support, or to fulfill specific machining requirements during CNC lathe machining.

[0003] For example, Chinese patent CN222726101U discloses an auxiliary positioning fixture for a vertical machining center of a CNC lathe, including a support platform. Fixed blocks are fixedly connected to both ends of the top of the support platform. An L-shaped through groove is opened on one side of each of the two fixed blocks. Two connecting blocks are fixedly connected to one side of each fixed block. Two sliders are slidably engaged inside the two L-shaped through grooves.

[0004] In the aforementioned patent, although the problem of inconvenience in picking up and placing large parts is solved by using threaded rods and fixed crossbars, the height of the fixed crossbar is adjusted by manually rotating the bolts, which cannot quickly adapt to the use of workpieces of different sizes. During the adjustment process, human error can easily lead to positioning deviations, affecting the clamping effect. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the height of the fixed crossbar in the existing technology relies on manual rotation of the bolt for adjustment, which cannot quickly adapt to the use of workpieces of different sizes. During the adjustment process, human operation errors can easily lead to positioning deviations, affecting the clamping effect. Therefore, an auxiliary tooling for CNC lathes for automotive parts is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary tooling for a CNC lathe for automotive parts, comprising a support platform, an L-shaped frame 1 fixedly connected to the bottom of the support platform, a clamping auxiliary mechanism provided on one side of the L-shaped frame 1, the clamping auxiliary mechanism including a pressure sensor, a placement plate and grippers, an mounting plate fixedly connected to one side of the pressure sensor, and a gripper fixedly connected to one side of the mounting plate, with two grippers respectively bolted to the two ends of a hydraulic cylinder, the placement plate and the support platform being slidably connected, a support rod 2 rotatably connected to the bottom of the placement plate, a pin inserted through one end of the support rod 2, the support rod 1 being hinged to the support rod 2 via the pin, the L-shaped frame 2 rotatably connected to the bottom of the support rod 1, and the top of the L-shaped frame 2 being fixedly connected to the support platform.

[0007] Preferably, the bottom of the hydraulic cylinder is fixedly connected to the support platform, and the top of the support platform is slidably connected to one of the grippers.

[0008] Preferably, a support block is fixedly connected to the top of the L-shaped frame 2, an electric push rod 2 is fixedly connected to one side of the support block, and a connector is fixedly connected to one end of the electric push rod 2.

[0009] Preferably, the connector is penetrated by a pin, and the connector and the pin are rotatably connected.

[0010] Preferably, a motor is embedded inside the L-shaped frame, and a bevel gear is fixedly connected to one end of the motor's output shaft, with the bevel gear rotatably connected to the L-shaped frame.

[0011] Preferably, the top of the L-shaped frame is engaged with a bevel gear, the top of which penetrates the side wall of the support platform, and the bevel gear is rotatably connected to the support platform.

[0012] Preferably, an electric push rod is fixedly connected to the top of the bevel gear, a connecting frame is fixedly connected to the top of the electric push rod, and a pressure plate is fixedly connected to one end of the connecting frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, one end of the electric push rod is fixedly connected to the pin shaft, and one side of the mounting plate is connected to the gripper. The electric push rod 2 extends and retracts to drive the pin shaft to move, changing the angle formed by the support rod 1 and the support rod 2, and adjusting the height of the placement plate. This allows the mounting plate to change the clamping position of the parts, adapting to workpieces of different sizes.

[0015] 2. In this utility model, the pressure plate is fixedly connected to the connecting frame, and the first bevel gear and the second bevel gear are fixedly connected. The motor drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear and the first electric push rod to rotate. This can change the usage direction of the pressure plate and the connecting frame. The usage height of the pressure plate and the connecting frame can be adjusted by the first electric push rod. The pressure plate is used to press the top of the part, and when used in combination with the gripper, it ensures that the center of gravity of the part is stably constrained and the stability of the clamping is guaranteed.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: An auxiliary tooling for a CNC lathe for automotive parts includes a support platform 5. An L-shaped frame 8 is fixedly connected to the bottom of the support platform 5. A clamping auxiliary mechanism is provided on one side of the L-shaped frame 8. The clamping auxiliary mechanism includes a pressure sensor 9, a placement plate 10, and grippers 11. A mounting plate 18 is fixedly connected to one side of the pressure sensor 9, and one side of the mounting plate 18 is fixedly connected to the grippers 11. The two grippers 11 are respectively bolted to the two ends of a hydraulic cylinder 12. The placement plate 10 is slidably connected to the support platform 5. A second support rod 17 is rotatably connected to the bottom of the placement plate 10, with one end of the second support rod 17 passing through... A pin 19 is inserted, and a second support rod 17 is hinged to a first support rod 14 via the pin 19. The bottom of the first support rod 14 is rotatably connected to an L-shaped frame 16. The top of the L-shaped frame 16 is fixedly connected to a support platform 5. The bottom of the hydraulic cylinder 12 is fixedly connected to the support platform 5. The top of the support platform 5 is slidably connected to one of the grippers 11. A support block is fixedly connected to the top of the L-shaped frame 16. An electric push rod 15 is fixedly connected to one side of the support block. A connector 13 is fixedly connected to one end of the electric push rod 15. The connector 13 is penetrated by the pin 19, and the connector 13 is rotatably connected to the pin 19.

[0024] The pressure sensor 9 can be installed on one side of the gripper 11 using the mounting plate 18. The distance between the two mounting plates 18 can be adjusted by the hydraulic cylinder 12, thereby clamping the automotive parts. The L-shaped bracket 16 can support the bottom of the support rod 14. The support block can ensure the stable installation and use of the two electric push rods 15. The electric push rods 15 can provide power for the movement of the pin 19, thereby changing the distance between the two pins 19, and thus changing the angle formed between the support rod 14 and the support rod 17. This adjusts the height of the placement plate 10, allowing the parts to rise and fall synchronously with the placement plate 10, changing the contact position between the mounting plate 18 and the parts, reducing the center of gravity shift when the mounting plate 18 clamps the parts, and making it suitable for parts of different heights.

[0025] Example 2: Figure 1 and Figure 2 As shown, a motor 4 is embedded inside the L-shaped frame 8. One end of the output shaft of the motor 4 is fixedly connected to a bevel gear 7. The bevel gear 7 is rotatably connected to the L-shaped frame 8. A bevel gear 6 is meshed at the top of the L-shaped frame 8. The top of the bevel gear 6 passes through the side wall of the support platform 5. The bevel gear 6 is rotatably connected to the support platform 5. An electric push rod 3 is fixedly connected to the top of the bevel gear 6. A connecting frame 2 is fixedly connected to the top of the electric push rod 3. A pressure plate 1 is fixedly connected to one end of the connecting frame 2.

[0026] The L-shaped frame 8 can support the motor 4, which in turn provides power for the rotation of the bevel gear 7. The meshing of the bevel gear 7 with the bevel gear 6 drives the bevel gear 6 to rotate when the bevel gear 7 rotates. The bevel gear 6 rotates synchronously with the electric push rod 3, which can change the position of the pressure plate 1 and the connecting frame 2. The electric push rod 3 can adjust the height of the pressure plate 1 and the connecting frame 2, thereby controlling the contact or separation between the bottom of the pressure plate 1 and the parts.

[0027] The operating method and working principle of this device are as follows: First, place the automotive parts to be processed on the placement plate 10. Select the processing position of the gripper 11 according to the height of the parts. When the height of the parts is low, the electric push rod 15 retracts, driving the pin 19 to move closer to the electric push rod 15. At this time, the distance between the two pins 19 decreases, and the angle between the support rod 14 and the support rod 17 increases. The placement plate 10 moves upward along the support platform 5, adjusting the clamping position of the parts. The hydraulic cylinder 12 retracts, driving one of the grippers 11 to move. The movement causes both mounting plates 18 to contact the edge of the part. The external control terminal detects the clamping status of the part based on the pressure data detected by the pressure sensor 9. When the clamping force is too large and exceeds the predetermined value, the position of the mounting plate 18 can be adjusted. The electric push rod 1-3 drives the pressure plate 1 and the connecting frame 2 to move down, so that the bottom of the pressure plate 1 presses against the part. When the pressure plate 1 is not needed, the motor 4 drives the bevel gear 2-7 to rotate, and the bevel gear 2-7 drives the bevel gear 6 to rotate. The pressure plate 1 and the connecting frame 2 rotate around the axis of the electric push rod 1-3 and move away from the part.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
