Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an intelligent floating fixture for the production of precision parts. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for operation or inspection; it is also called a clamp. In a broader sense, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture.

[0003] In the machining of precision parts, it is often necessary to adjust the vertical position of the parts to meet different machining requirements. However, existing fixtures usually require the workpiece to be removed from the fixture and re-fixed when adjusting the vertical position of the parts. During the re-fixing process, the parts are prone to misalignment, which affects the machining accuracy and reduces production efficiency and product quality.

[0004] Therefore, it is necessary to modify it by setting a floating mechanism to conveniently adjust the vertical position of the parts without removing and re-fixing them, thereby avoiding misalignment and improving processing accuracy and production efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an intelligent floating fixture for precision parts production. This fixture features a floating mechanism that allows for convenient adjustment of the vertical position of parts without requiring removal and re-fixation, thus preventing misalignment and improving machining accuracy and production efficiency. It solves the problem that existing fixtures typically require removing the workpiece from the fixture and re-fixing it when adjusting the vertical position, which can easily lead to misalignment, affecting machining accuracy and reducing production efficiency and product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent floating fixture for precision parts production, comprising a base, a support plate fixedly connected to the top of the base via legs, square slots extending vertically through the front and rear sides of the support plate, and a first cylinder disposed inside the square slots, the bottom end of the first cylinder being fixedly connected to the top of the base, and a lifting platform located above the support plate being fixedly connected to the top of the first cylinder, a double-headed cylinder being fixedly connected to the bottom of the support plate, and a movable frame being fixedly connected to the output ends on both sides of the double-headed cylinder, a support rod being slidably connected inside the movable frame, and a support rod being fixedly connected to the front and rear sides of the inner side of the support rod, and a clamping mechanism being fixedly connected to the inner end of the support rod.

[0007] In a preferred embodiment of this utility model, the clamping mechanism includes a transverse clamping plate fixedly connected to the inner end of the support rod, a longitudinal baffle fixedly connected to the front of the inner side of the transverse clamping plate, a second cylinder fixedly connected to the upper outer side of the transverse clamping plate, an L-shaped push rod fixedly connected to the output end of the second cylinder, a longitudinal clamping plate fixedly connected to the front end of the L-shaped push rod, and the front side of the longitudinal clamping plate fitting against the back side of the longitudinal baffle.

[0008] As a preferred embodiment of this utility model, damping telescopic rods are fixedly connected to both the front and rear sides of the lower inner wall of the movable frame. The top end of the damping telescopic rod is fixedly connected to the bottom of the support rod. A buffer spring is sleeved on the surface of the damping telescopic rod. The top end of the buffer spring is fixedly connected to the bottom of the support rod, and the bottom end of the buffer spring is fixedly connected to the bottom of the inner wall of the movable frame.

[0009] As a preferred embodiment of this utility model, circular grooves are provided on both the front and rear sides of the left and right sides of the bearing plate, and a stabilizing rod is slidably connected inside the circular groove. The outer end of the stabilizing rod is fixedly connected to the inner side of the movable frame.

[0010] As a preferred embodiment of this utility model, T-shaped blocks are fixedly connected to both the front and rear ends of the support rod, and T-shaped grooves that cooperate with the T-shaped blocks are opened on both the front and rear sides of the inner wall of the movable frame. The surface of the T-shaped block is slidably connected to the inner wall of the T-shaped groove.

[0011] As a preferred embodiment of this utility model, rubber pads are fixedly connected to the inner sides of the transverse clamping plate, the longitudinal clamping plate, and the longitudinal baffle, and a buffer pad is fixedly connected to the top of the lifting platform. The surfaces of the rubber pads and the buffer pads are provided with anti-slip textures.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a double-headed cylinder to extend the clamping mechanism. When extended, the cylinder drives two movable frames to move outwards synchronously, moving the clamping mechanism away from the space above the lifting platform. The part to be processed is then placed above the lifting platform, and the second cylinder is activated to open the clamping mechanism. The double-headed cylinder then retracts, causing the two clamping mechanisms to move closer together and clamp the part laterally. After lateral clamping, the second cylinder can be retracted to clamp the part longitudinally, thus fixing it for processing. When the vertical position of the part needs adjustment, the first cylinder is activated to move the lifting platform upwards, raising the part; conversely, retracting the first cylinder lowers the part. This achieves the effect of conveniently adjusting the vertical position of the part without removing and re-fixing it, preventing part misalignment, and improving processing accuracy and production efficiency.

[0014] 2. This utility model, through the combined use of a transverse clamping plate, a longitudinal baffle, a second cylinder, an L-shaped push rod, and a longitudinal clamping plate, allows the second cylinder to extend and open the space between the longitudinal baffle and the longitudinal clamping plate. The transverse clamping plate then clamps the part laterally. Once the part is clamped laterally, the second cylinder retracts, causing the L-shaped push rod and the longitudinal clamping plate to move and clamp the part longitudinally. This improves the fixation effect on the part and enhances the machining accuracy. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 4As shown, the present invention provides an intelligent floating fixture for precision parts production, comprising a base 1, a support plate 2 fixedly connected to the top of the base 1 via support legs, a through square groove on both the front and rear sides of the support plate 2, and a first cylinder 3 disposed inside the square groove, the bottom end of the first cylinder 3 being fixedly connected to the top of the base 1, the top end of the first cylinder 3 being fixedly connected to a lifting platform 4 located above the support plate 2, a double-headed cylinder 5 being fixedly connected to the bottom of the support plate 2, a movable frame 6 being fixedly connected to the output ends on both the left and right sides of the double-headed cylinder 5, a support rod 7 being slidably connected inside the movable frame 6, a support rod 8 being fixedly connected to the front and rear sides of the inner side of the support rod 7, and a clamping mechanism 9 being fixedly connected to the inner end of the support rod 8.

[0022] refer to Figure 3 The clamping mechanism 9 includes a transverse clamping plate 10 fixedly connected to the inner end of the support rod 8. A longitudinal baffle 11 is fixedly connected to the front of the inner side of the transverse clamping plate 10. A second cylinder 12 is fixedly connected to the upper outer side of the transverse clamping plate 10. An L-shaped push rod 13 is fixedly connected to the output end of the second cylinder 12. A longitudinal clamping plate 14 is fixedly connected to the front end of the L-shaped push rod 13. The front side of the longitudinal clamping plate 14 is in contact with the back side of the longitudinal baffle 11.

[0023] As a technical optimization of this utility model, by setting up the cooperation of the transverse clamping plate 10, the longitudinal baffle 11, the second cylinder 12, the L-shaped push rod 13 and the longitudinal clamping plate 14, the second cylinder 12 can extend to open the space between the longitudinal baffle 11 and the longitudinal clamping plate 14, and the part can be clamped laterally by the transverse clamping plate 10. After the part is clamped laterally, the second cylinder 12 can retract to drive the L-shaped push rod 13 and the longitudinal clamping plate 14 to move and clamp the part longitudinally, thereby improving the fixing effect of the part and improving the processing accuracy.

[0024] refer to Figure 1 Damping telescopic rods 15 are fixedly connected to the front and rear sides of the inner wall of the movable frame 6. The top of the damping telescopic rod 15 is fixedly connected to the bottom of the support rod 7. A buffer spring 16 is sleeved on the surface of the damping telescopic rod 15. The top of the buffer spring 16 is fixedly connected to the bottom of the support rod 7, and the bottom of the buffer spring 16 is fixedly connected to the bottom of the inner wall of the movable frame 6.

[0025] As a technical optimization of this utility model, the damping telescopic rod 15 and the buffer spring 16 are used in combination to support and buffer the support rod 7 and the clamping plate mechanism 9. When the support rod 7 and the clamping plate mechanism 9 move up and down, the damping telescopic rod 15 and the buffer spring 16 extend and retract accordingly, making the movement smoother and more stable, and convenient to use.

[0026] refer to Figure 1The bearing plate 2 has circular grooves on both the front and rear sides of the left and right sides, and a stabilizing rod 17 is slidably connected inside the circular groove. The outer end of the stabilizing rod 17 is fixedly connected to the inner side of the moving frame 6.

[0027] As a technical optimization of this utility model, by setting a stabilizing rod 17, when the double-headed cylinder 5 extends and retracts to drive the moving frame 6 to move, the stabilizing rod 17 moves inside the circular groove, which plays a supporting and reinforcing role on the front and rear sides of the moving frame 6, and avoids the moving frame 6 from swaying and tilting during movement, which would affect normal use.

[0028] refer to Figure 4 T-shaped blocks 18 are fixedly connected to both the front and rear ends of the support rod 7. T-shaped grooves 19 that cooperate with the T-shaped blocks 18 are opened on both the front and rear sides of the inner wall of the movable frame 6. The surface of the T-shaped block 18 is slidably connected to the inner wall of the T-shaped groove 19.

[0029] As a technical optimization of this utility model, by setting the T-shaped block 18 and the T-shaped groove 19 in cooperation, when the first cylinder 3 is started and drives the part to move up and down, the clamping mechanism 9 and the support rod 7 move accordingly. The T-shaped block 18 slides inside the T-shaped groove 19, which plays a stabilizing and limiting role on the support rod 7 and the clamping mechanism 9, so that they can only move vertically up and down, avoiding tilting and shaking, and making their movement smoother.

[0030] refer to Figure 1 Rubber pads 20 are fixedly connected to the inner sides of the transverse clamping plate 10, the longitudinal clamping plate 14 and the longitudinal baffle 11. A buffer pad 21 is fixedly connected to the top of the lifting platform 4. Anti-slip textures are provided on the surface of the rubber pad 20 and the surface of the buffer pad 21.

[0031] As a technical optimization of this utility model, by setting a rubber pad 20, when the part is fixed by two transverse clamps 10, a longitudinal clamp 14 and a longitudinal baffle 11, the surface of the part contacts the rubber pad 20, which avoids wear on the part and increases friction to make the clamping of the part more secure. By setting a buffer pad 21, the bottom of the part is protected.

[0032] The working principle and usage process of this utility model are as follows: By activating the double-headed cylinder 5 to extend it, the double-headed cylinder 5 drives the two moving frames 6 to move outward synchronously, moving the clamping mechanism 9 away from the space above the opening lifting platform 4. Then, the part to be processed is placed above the lifting platform 4, and the second cylinder 12 is activated to open the clamping mechanism 9. Then, the double-headed cylinder 5 is retracted, driving the two clamping mechanisms 9 to move closer to each other to clamp the part laterally. After the lateral clamping is completed, the second cylinder 12 can be controlled to retract to clamp the part longitudinally, thereby fixing the part for processing. When it is necessary to adjust the vertical position of the part, the first cylinder 3 can be activated to push the lifting platform 4 upward to raise the part. Conversely, retracting the first cylinder 3 lowers the part. This achieves the effect of conveniently adjusting the vertical position of the part without removing and re-fixing it by setting a floating mechanism, avoiding part misalignment, and improving processing accuracy and production efficiency.
