Description

Technical Field

[0001] This utility model relates to a tooling fixture, specifically a multi-station rotating tooling fixture, belonging to the field of fixture technology. Background Technology

[0002] Tooling, also known as process equipment, is a general term for all tools used in the manufacturing process, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, and workstation fixtures. Among them, fixtures are an important component of tooling, used to clamp workpieces or guide cutting tools, ensuring that the workpiece maintains a precise position during processing. Fixtures are also called clamps. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces at any stage of the manufacturing process can be called a fixture.

[0003] In existing technologies, such as the tooling fixture disclosed in CN220331246U, there is a base, a movable plate, two support plates, two adjustment modules, two clamping plates, and two clamping drive modules. Both support plates are slidably mounted on the base. One end of each adjustment module is connected to the base, and the other end is connected to a support plate. The support plates reciprocate along the base via the adjustment modules. The two ends of the movable plate are respectively engaged with the two support plates, and the clamping plates are positioned between the two support plates. The position of the two support plates between the base can be determined by the adjustment modules and the movable plate. The clamping drive modules drive one clamping plate to move closer to the opposite clamping plate to clamp the workpiece. The structure is simple.

[0004] Although the above technical solution can clamp the workpiece by adjusting the position of the two support plates between the base through the adjustment module and the movable plate, it cannot adjust the workpiece after clamping, and cannot ensure the stability and accuracy of the workpiece during the processing, resulting in poor practicality. Therefore, a multi-station rotating tooling fixture is provided to overcome the above defects. Utility Model Content

[0005] This utility model provides a multi-station rotating tooling fixture to solve the problems mentioned above, such as the inability to adjust the clamped workpiece, the inability to ensure the stability and accuracy of the workpiece during processing, and the poor practicality of the workpiece.

[0006] The present invention achieves the above objectives through the following technical solution: a multi-station rotating tooling fixture, including a fixture base, a movable plate provided above the fixture base, an adjustment mechanism for adjusting the fixture inside the fixture base, and a fixing mechanism for fixing the height of the fixture below the fixture base.

[0007] The adjustment mechanism includes an adjustment motor, which is fixed inside the clamp base by bolts. The power output shaft of the adjustment motor is fixed with a drive gear, and a driven gear meshes with one side of the drive gear. A transmission rod that is fixedly connected to the movable plate is fixed to the upper end of the drive gear.

[0008] As a further improvement of this utility model: the outer surface of the transmission rod is fitted with a fixed bearing that is embedded in the upper surface of the clamp base.

[0009] As a further improvement of this utility model: four clamping electric cylinders are fixed to the upper surface of the movable plate by bolts, and a fixing plate is installed on the upper end of each of the four clamping electric cylinders.

[0010] As a further improvement of this utility model: each of the four telescopic ends of the clamping electric cylinders is fixed with a clamping plate, and the inner wall of the clamping plate is fixed with a protective rubber pad.

[0011] As a further embodiment of this utility model: the fixing mechanism includes an adjusting member, which is disposed below the clamp base, and a fixing seat is fixed on the lower surface of the adjusting member.

[0012] As a further embodiment of this utility model: the internal telescopic connection of the adjusting member is a connecting rod that is fixedly connected to the clamp base, the internal thread of the connecting rod is a lead screw, and the input end of the lead screw is fixed with a stepper motor.

[0013] As a further improvement of this utility model: two guide tubes are symmetrically fixed at the upper end of the fixed base, and the interior of each of the two guide tubes is telescopically connected with a guide rod that is fixedly connected to the clamp base.

[0014] The beneficial effects of this utility model are: it can drive the movable plate to rotate, so that the second clamped workpiece rotates to the bottom of the processing equipment, and can continuously process the workpiece. The fixed bearing can ensure the stability of the transmission rod rotation, thereby realizing the function of adjusting the clamped workpiece.

[0015] The screw rotation drives the threaded connecting rod to move vertically. The guide tube connected to the guide rod plays a guiding role, preventing the fixture base from shifting during movement. This allows for adjustment of the height of the fixture base, facilitating the overall height adjustment of the tooling fixture. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a multi-station rotating tooling fixture includes a fixture base 1, a movable plate 2 is provided above the fixture base 1, an adjustment mechanism for adjusting the fixture is provided inside the fixture base 1, and a fixing mechanism for fixing the height of the fixture is provided below the fixture base 1.

[0023] The adjustment mechanism includes an adjustment motor 3, which is bolted to the inside of the clamp base 1. A drive gear 31 is fixed to the power output shaft of the adjustment motor 3. A driven gear 32 meshes with one side of the drive gear 31. A transmission rod 33, which is fixedly connected to the movable plate 2, is fixed to the upper end of the drive gear 31. A fixed bearing 34, embedded in the upper surface of the clamp base 1, is sleeved on the outer surface of the transmission rod 33. Four clamping electric cylinders 4 are bolted to the upper surface of the movable plate 2. A fixed plate 5 is installed at the upper end of each of the four clamping electric cylinders 4. A clamping plate 6 is fixed to the telescopic end of each of the four clamping electric cylinders 4. A protective rubber pad 7 is fixed to the inner wall of the clamping plate 6. The clamping electric cylinders 4 on the movable plate 2 are used to adjust the clamping mechanism. The workpiece is placed on the fixed plate 5, and the clamping electric cylinder 4 drives the two clamping plates 6 to move closer to each other, thereby clamping and fixing the workpiece. The protective rubber pad 7 can prevent damage to the workpiece during clamping and facilitate subsequent grinding. The adjusting motor 3 installed in the fixture base 1 drives the driving gear 31 to mesh with the driven gear 32 to rotate after the first workpiece is processed. This drives the transmission rod 33 to rotate synchronously, causing the movable plate 2 to rotate, so that the second clamped workpiece rotates to the bottom of the processing equipment, enabling continuous processing of the workpiece. The fixed bearing 34 ensures the stability of the rotation of the transmission rod 33, thereby achieving the function of adjusting the clamped workpiece. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a fixing mechanism comprising an adjusting member 8, the adjusting member 8 being disposed below the fixture base 1, a fixing seat 81 being fixed to the lower surface of the adjusting member 8, a connecting rod 82 being telescopically connected to the adjusting member 8 and fixedly connected to the fixture base 1, a lead screw 83 being threadedly connected to the connecting rod 82, a stepper motor 84 being fixed to the input end of the lead screw 83, and two guide tubes 86 being symmetrically fixed to the upper end of the fixing seat 81, each of the two guide tubes 86 being telescopically connected to a guide rod 85 fixedly connected to the fixture base 1. The stepper motor 84 provided in the adjusting member 8 can drive the lead screw 83 to rotate, causing the lead screw 83 to rotate and drive the threaded connecting rod 82 to move vertically. The guide tubes 86 connected to the guide rods 85 can play a guiding role, preventing the fixture base 1 from shifting during movement. This allows for adjustment of the height of the fixture base 1, facilitating the overall height adjustment of the tooling fixture.

[0025] Working principle: Before using this multi-station rotary fixture, place it in a suitable position. The fixed base 81 ensures the overall stability of the fixture. During use, the workpiece to be processed is placed on the fixed plate 5 by the clamping electric cylinder 4 on the movable plate 2. The clamping electric cylinder 4 drives the two clamping plates 6 to move closer together, thereby clamping and fixing the workpiece. The protective rubber pad 7 prevents damage to the workpiece during clamping, facilitating subsequent grinding. The adjusting motor 3 in the fixture base 1 drives the drive gear 31 to mesh with the driven gear 32 and rotate after the first workpiece is processed, thereby synchronously driving the transmission rod 33 to rotate. The movable plate 2 rotates, causing the second clamped workpiece to rotate to the bottom of the processing equipment, enabling continuous processing of the workpiece. The fixed bearing 34 ensures the stability of the rotation of the transmission rod 33, thereby achieving the function of adjusting the clamped workpiece. The stepper motor 84 installed in the adjusting component 8 drives the lead screw 83 to rotate, causing the threaded connecting rod 82 to move vertically. The guide tube 86 connected to the guide rod 85 plays a guiding role, preventing the fixture base 1 from shifting during movement. This allows for adjustment of the height of the fixture base 1, facilitating the overall height adjustment of the tooling fixture and making it suitable for use in different environments.
