Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically relating to a multi-station pressure measuring and clamping mechanism. Background Technology

[0002] Tooling fixtures are specialized process equipment used in manufacturing, with the core function of precisely fixing workpieces. Through mechanical, pneumatic, or hydraulic structures, they ensure that the parts to be processed remain stable in a predetermined position, thereby guaranteeing accurate and consistent machining dimensions, improving production efficiency, and effectively reducing the operational burden of repetitive positioning. From simple mechanical modules to complex automated systems, tooling fixtures are a crucial foundation for achieving efficient, high-quality, and large-scale manufacturing.

[0003] There is a workpiece 9, which needs to have a connecting hole 92 machined on a polygonal head 91 that communicates with the interior of the workpiece 9. Since there is no opposing clamping surface between the workpiece 9 and the polygonal head 91, it can only be clamped from the outside of the polygonal head 91. The traditional clamping method is to use two clamping blocks and a cylinder to clamp and position them. However, the cylinder is arranged vertically, and its direction is consistent with the working direction of the tool, which will cause some interference. In addition, it increases the height of the workpiece, which is not conducive to the compactness of the processing equipment.

[0004] To address the aforementioned issues, this application proposes a multi-station pressure measuring and clamping mechanism. Utility Model Content

[0007] As a preferred technical solution of this utility model, the fixed base is formed with a trapezoidal platform with a sloping side, and one side of the clamping block is formed with a sloping surface that slides in contact with the sloping side of the trapezoidal platform.

The extension rod at the front end of the hydraulic cylinder passes through the first connecting hole, the second connecting hole, and the guide hole and is connected to the clamping block. The clamping block is slidably connected to the extension rod through the waist-shaped groove.

[0008] As a preferred technical solution of this utility model, the clamp includes a base fixed to the positioning plate, a stop block fixed on the base, and a boss integrally formed on the base that matches the bottom surface of the polygonal head.

[0009] As a preferred embodiment of this utility model, the clamping base is formed with a first groove, the clamping block is formed with a second groove corresponding to the first groove, and the abutment is formed with a machining groove corresponding to the connecting hole.

[0010] As a preferred technical solution of this utility model, the inclined side of the trapezoidal platform is provided with a guide groove, and a guide block is fixed on the inclined surface of the clamping block and slides in cooperation with the guide groove.

[0011] As a preferred embodiment of this utility model, a motor is installed on the L-shaped turntable, and the output end of the motor is fixed to the rotation shaft of the base plate.

[0012] As a preferred embodiment of this utility model, the positioning plate is provided with a positioning groove corresponding to the fixing seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention places the hydraulic cylinder at the bottom of the base plate, and then achieves side clamping through the interaction of the fixed seat and the clamping block. This clamping method shortens the overall length of the mechanism, thereby leaving sufficient space for the tool to move above, avoiding interference between the clamp and the tool, and ensuring clamping stability.

[0015] 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

[0016] Please see Figures 1-8 The present invention provides the following technical solution: a multi-station pressure measuring and clamping mechanism, including a fixed plate 1, an L-shaped turntable 2 fixedly installed on the fixed plate 1, a rotating base plate 3 on the L-shaped turntable 2, a positioning plate 4 fixed on the base plate 3, a corresponding clamping seat 5 and a fixed seat 6 fixed on the positioning plate 4, and a movable clamping block 7 on the fixed seat 6; the workpiece 9 is clamped by the moving force formed by the squeezing of the inclined surface 71 on the clamping block 7 and the inclined side on the trapezoidal platform 61, in conjunction with the clamping seat 5.

[0017] Furthermore, a trapezoidal platform 61 with a sloping side is formed on the fixed base 6, and a sloping surface 71 is formed on one side of the clamping block 7 to slide in contact with the sloping side of the trapezoidal platform 61. A hydraulic cylinder 8 is installed in the recess 31 at the bottom of the base plate 3. The extension rod 81 at the front end of the hydraulic cylinder 8 passes through the first connecting hole 32, the second connecting hole 42, and the guide hole 62 and is connected to the clamping block 7. The clamping block 7 is slidably connected to the extension rod 81 through the waist-shaped groove 74.

[0018] Furthermore, the clamping components include a clamping base 5, a fixed base 6, a clamping block 7, and a hydraulic cylinder 8. The clamping components are provided in two sets side by side, with the two sets of clamping components arranged vertically. In order to facilitate the switching of workpieces 9, a motor 21 is installed on the L-shaped turntable 2, and the output end of the motor 21 is fixed to the rotation shaft of the base plate 3. Specifically, the clamping components at the upper end of the positioning plate 4 are the processing station, and the clamping components at the lower end are the loading and unloading station.

[0019] Furthermore, the clamp 5 includes a base 51 fixed to the positioning plate 4, a stop block 52 fixed on the base 51, and a boss 511 integrally formed on the base 51 that matches the bottom surface of the polygonal head 91. The boss 511 provides stable support from the bottom of the polygonal head 91 and also plays a positioning role when placed.

[0020] Furthermore, in order to stably clamp the outer side of the polygonal head 91, a first groove 521 is formed on the clamping base 5, a second groove 73 corresponding to the first groove 521 is formed on the clamping block 7, and a machining groove 522 corresponding to the connecting hole 92 is formed on the abutment block 52. In actual use, the tool makes a hole in the connecting hole 92 through the machining groove 522.

[0021] Furthermore, in order to prevent the sliding deviation between the fixed seat 6 and the clamping block 7, the inclined side of the trapezoidal platform 61 is provided with a guide groove 611, and a guide block 72 is fixed on the inclined surface 71 of the clamping block 7 and slides in cooperation with the guide groove 611.

[0022] Furthermore, in order to prevent the fixed seat 6 from shifting during the process of the hydraulic cylinder 8 pulling the clamping block 7, the positioning plate 4 is provided with a positioning groove 41 corresponding to the fixed seat 6.

[0023] The working principle and usage process of this utility model: Under normal conditions, the hydraulic cylinder 8 is in the upward state. At this time, the polygonal head 91 on the workpiece 9 is attached to the first groove 521 and placed on the boss 511. The hydraulic cylinder 8 is started to pull the clamping block 7 towards the fixed seat 6. Under the action of the inclined surface 71 and the inclined surface of the trapezoidal platform 61, the clamping block 7 is driven to tilt towards the workpiece 9 and move downward. The waist-shaped groove 74 slides outside the extension rod 81 following the movement of the clamping block 7 until the second groove 73 presses the workpiece 9 tightly on the clamping seat 5. During the movement of the clamping block 7, the guide block 72 moves in the guide groove 611. After one side of the workpiece 9 is processed, the upper connecting part of the base plate 3 is flipped by the motor 21 to achieve rapid switching.

[0024] Unloading: Hydraulic cylinder 8 moves in the reverse direction, clamping block 7 moves upward. At this time, the second groove 73 will not directly detach from the workpiece 9, but it has lost its holding force. Guide block 72 slides in guide groove 611 but does not completely detach. Workpiece 9 can be removed by workers or mechanical grippers.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
