Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to a tooling fixture with angled pull-down locking. Background Technology

[0002] A tooling fixture is a device used to fix a workpiece to ensure its stability during processing. It can be used to determine the correct position of the workpiece in the fixture, so that the workpiece is accurately positioned during processing. For example, V-blocks can be used to position circular workpieces, and planar positioning blocks can be used to position workpieces with flat surfaces.

[0003] In existing technologies, some workpieces are tilted during processing. To facilitate processing, the fixture is also tilted. This makes processing easier. However, when the fixture is tilted, it cannot fix the initial position of the workpiece. When the workpiece is placed directly on top, it will fall down along the tilted upper part of the fixture. If the fixture is adjusted every time it is clamped, the next set of workpieces will be clamped after the previous set is clamped, resulting in low processing efficiency and inconvenience in operation. Therefore, a fixture with angled pull-down locking is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tooling fixture with angled pull-down locking, which aims to improve the problem in the prior art that "when the tooling fixture itself is set to an inclined position, it cannot fix the initial position of the workpiece well, which is inconvenient during operation".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tooling fixture with angled pull-down locking, comprising a fixed plate, an inclined platform on the upper surface of the fixed plate, a base plate mounted on the upper surface of the inclined platform, a support plate mounted on the upper surface of the base plate, a top plate mounted on the upper surface of the support plate, a cylinder mounted on the lower surface of the top plate, a fixed flange mounted on the upper surface of the top plate, a clamp fixedly connected to the upper end of the fixed flange, a pressing head fixedly connected to the upper end of the cylinder output shaft, a connection port on the front surface of the cylinder, and a control component on the front surface of the cylinder.

[0006] As a further description of the above technical solution: The control component includes a connecting block, which is fixedly connected to the front surface of the cylinder. The front surface of the connecting block is provided with a vent hole, which is adapted to the connection port.

[0007] As a further description of the above technical solution: The front surface of the vent is equipped with an air intake pipe and an exhaust pipe from top to bottom.

[0008] As a further description of the above technical solution: The upper surface of the connecting block is slidably connected to a control plate, and the front surface of the control plate is provided with a through hole.

[0009] As a further description of the above technical solution: The control assembly also includes a sliding sleeve that slides on the outer wall of the jacket and is fixedly connected to the control plate.

[0010] As a further description of the above technical solution: A return spring is fixedly connected to the lower end of the sliding sleeve, and the lower end of the return spring is fixedly connected to the upper surface of the fixed flange.

[0011] As a further description of the above technical solution: The jacket is designed in a stepped shape.

[0012] As a further description of the above technical solution: The cylinder, extrusion head, fixed flange, jacket, and control components are arranged in multiple sets, and these multiple sets of cylinders, extrusion heads, fixed flanges, jackets, and control components are arranged side by side on the outer wall of the top plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting up a control component, during processing, the air inlet pipe can be connected first, and then the workpiece to be processed can be sleeved on the surface of the clamp. After that, the control plate can be pulled down to drive the through hole to connect with the air hole. In this way, the cylinder will push the extrusion head to squeeze the clamp and make it open outward, thus fixing the workpiece. The whole device does not need to repeatedly adjust the air inlet pipe during operation, which is more convenient during operation.

[0014] 2. In this utility model, by setting a sliding sleeve, when the operator puts the workpiece on the outer wall of the clamp, the workpiece moves downward and squeezes the sliding sleeve to move downward, thus automatically driving the control plate to move downward without the operator having to press it manually. The whole device is relatively fast to operate. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a tooling fixture with angled pull-down locking, comprising a fixed plate 1 for supporting the overall device, an inclined platform 12 for supporting a base plate 2 on the upper surface of the fixed plate 1, and the base plate 2 mounted on the upper surface of the inclined platform 12. By using the inclined platform 12 to support the base plate 2, the base plate 2 can be tilted. A support plate 3 for supporting a top plate 4 is mounted on the upper surface of the base plate 2, and a top plate 4 for supporting a fixed flange 8 is mounted on the upper surface of the support plate 3. A cylinder 10 is mounted on the lower surface of the top plate 4. The cylinder 10 is prior art and is ventilated. Then its output shaft will extend, and when the internal gas is discharged, its output shaft will move downward and return to its original position. A fixed flange 8 is installed on the upper surface of the top plate 4. A jacket 9 is fixedly connected to the upper end of the fixed flange 8. The outer wall of the jacket 9 is set with a groove, so that it has the ability to deform. When it is squeezed inside, it can expand and deform outward. A pressing head 11 for pressing the jacket 9 is fixedly connected to the upper end of the output shaft of the cylinder 10. A connection port 101 for airflow is provided on the front surface of the cylinder 10. A control component 7 for controlling the airflow is provided on the front surface of the cylinder 10.

[0019] Reference Figures 2-4The control component 7 includes a connecting block 71, which is fixedly connected to the front surface of the cylinder 10. The connecting block 71 can completely seal the front end connection port 101 of the cylinder 10, and the connection between it and the cylinder 10 is relatively tight, maintaining good airtightness. The front surface of the connecting block 71 is provided with a vent hole 72 for airflow. The vent hole 72 is adapted to the connection port 101. When airflow enters the vent hole 72, it can pass through the vent hole 72 and enter the connection port 101. From top to bottom, the front surface of the vent hole 72 is equipped with an intake pipe 5 and an exhaust pipe 6. The intake pipe 5 is connected to the high-pressure air transmission device. The connection is set, while the exhaust pipe 6 is connected to the air extraction device. When the operator starts the high-pressure air supply device, the air intake pipe 5 will be filled with high-pressure gas. The upper surface of the connecting block 71 is slidably connected to a control plate 73 for restricting airflow. The outer wall of the control plate 73 is made of rubber, which can maintain good sealing with the inner wall of the connecting block 71. The front surface of the control plate 73 is provided with a through hole 76 for air to pass through the control plate 73. By pulling down the control plate 73, the through hole 76 can be moved downward to connect with the vent 72, so that the airflow can enter the interior of the connection port 101 through the through hole 76.

[0020] Reference Figures 2-4 The control assembly 7 also includes a sliding sleeve 74 for moving the control plate 73. The sliding sleeve 74 slides on the outer wall of the sleeve 9 and can slide up and down on the outer wall of the sleeve 9. It can also separate from the outer wall of the sleeve 9. The sliding sleeve 74 is fixedly connected to the control plate 73. When the sliding sleeve 74 moves up and down, the control plate 73 is also moved synchronously. A return spring 75 for supporting the return of the sliding sleeve 74 is fixedly connected to the lower end of the sliding sleeve 74. The lower end of the return spring 75 is fixedly connected to the upper surface of the fixed flange 8. When the sliding sleeve 74 is not under pressure, the return spring 75 can push it to move upward and reset. The overall design of the jacket 9 is stepped, which allows the jacket 9 to adapt to workpieces of various sizes. There are multiple sets of cylinder 10, extrusion head 11, fixed flange 8, jacket 9, and control component 7. Multiple sets of cylinder 10, extrusion head 11, fixed flange 8, jacket 9, and control component 7 are arranged side by side on the outer wall of the top plate 4. Multiple sets of cylinder 10 can be supplied with air through the same set of air inlet pipes 5, which is more convenient for control.

[0021] Working principle: In the initial state, the sliding sleeve 74 is at the top of the clamping sleeve 9 under the action of the return spring 75. The through hole 76 of the control plate 73 and the vent hole 72 of the connecting block 71 are misaligned and separated. The cylinder 10 is not vented, the output shaft is in a retracted state, and the extrusion head 11 does not contact the inner wall of the clamping sleeve 9. When installing the workpiece, the workpiece is sleeved downward along the stepped outer wall of the clamping sleeve 9. The workpiece pushes the sliding sleeve 74 to compress the return spring 75 and slide downward, driving the control plate 73 to align and connect the through hole 76 and the vent hole 72. The high-pressure gas from the air inlet pipe 5 enters the cylinder 10 through the vent hole 72 and the connecting port 101, driving the output shaft to extend upward. The extrusion head 11 then extrudes upward to press the inner wall of the clamping sleeve 9. The clamping sleeve 9 expands outward and tightly fits the inner wall of the workpiece, completing the clamping and fixing.

[0022] During processing, the inclined table 12 tilts the base plate 2 and the workpiece at a preset angle. Multiple sets of cylinders 10 are supplied with air synchronously through the same air inlet pipe 5 to achieve multi-station fixation. After processing, the air inlet pipe 5 is closed and the exhaust pipe 6 is started to extract air. The gas in the cylinder 10 is discharged, the output shaft retracts and drives the extrusion head 11 to descend, and the clamp 9 elastically recovers and closes to release the workpiece. After the workpiece is removed, the return spring 75 pushes the sliding sleeve 74 and the control plate 73 to return to the starting position. The through hole 76 and the vent hole 72 are misaligned again, cutting off the air path. The device returns to the initial state. This fixture achieves rapid positioning and automatic locking of the tilted workpiece through the pneumatic linkage between the inclined table 12 structure and the control component 7.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
