Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a pin clamping fixture. Background Technology

[0002] A pin is a mechanical part primarily used for connection, positioning, or as a rotating shaft in mechanical structures. In connection, pins are used to connect the boom and tower of a construction crane, ensuring flexible rotation and easy disassembly. For positioning, the pin between the small end of the connecting rod and the piston in an automobile engine precisely positions them. As a rotating shaft, small manual rotary jigs rotate around the pin as a central axis, facilitating workpiece clamping and machining. Pins have smooth surfaces, require high diameter precision, have various end shapes, and are typically made of high-strength carbon steel or alloy steel.

[0003] A pin clamping fixture is a specialized tool used to fix and clamp pins. It mainly consists of a chuck, a clamping mechanism, and a base. The chuck is shaped to fit the pin's profile and is typically made of high-strength alloy steel. The clamping mechanism generates the clamping force. The base provides support. This fixture can clamp pins with high precision, ensuring positional accuracy during machining and assembly. It is versatile, interchangeable, and improves work efficiency.

[0004] Existing pin clamping fixtures cannot easily change the chuck according to the shape and size of the pin during the production process, which causes unnecessary time loss for workers and increases labor costs. Therefore, a new pin clamping fixture is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a pin clamping fixture, comprising two fixed frames 1, with related components of the fixed frames 1 providing stable support and protection. Both fixed frames 1 are externally slidably connected to a moving frame 2, which can drive related components to move under the drive of subsequent components. A fixed plate 3 is fixedly connected internally to the moving frame 2, providing fixation for related components. An insert plate 4 is also fixedly connected internally to the moving frame 2, providing guidance for subsequent components.

[0034] The motion frame 2 has a support plate 5 fixedly connected inside, which provides support for related components and improves the stability of the device. Both fixed frames 1 have clamping plates 6 fixedly connected inside, which can clamp the pin under the action of related components. A drive assembly is slidably connected to the bottom of the motion frame 2, providing stable power for the clamping operation. A lubrication assembly is fixedly connected inside the drive assembly, providing lubrication for related components.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The clamping assembly includes a pushing hydraulic press 7, which provides sufficient power for the operation of subsequent components. A pushing plate 8 is fixedly connected to the drive end of the pushing hydraulic press 7, and the pushing plate 8 pushes lubricant under the drive of the pushing hydraulic press 7. Sealing plates 9 are slidably connected to both ends of the pushing plate 8, and the sealing plates 9 cooperate with relevant components to prevent lubricant leakage. The external part of the pushing plate 8 is slidably connected to the inside of the drive assembly, and the drive assembly and relevant components cooperate to provide guidance and limitation for the movement of the pushing plate 8.

[0036] The drive assembly has two fixedly connected limiting plates 10, which provide limiting and guiding for subsequent components. Two guide blocks 11 are slidably connected to adjacent ends of the two limiting plates 10, which can evenly apply lubricant under the drive of the subsequent components. A slider 12 is fixedly connected to the bottom end of each guide block 11, which provides limiting for the movement of the subsequent components.

[0037] Reference Figures 2 to 4The drive assembly includes a base 13, which provides support and limits for related components. A double-headed hydraulic press 14 is fixedly connected inside the base 13, providing stable power output for the operation of subsequent components. Drive blocks 17 are fixedly connected to the drive ends of the double-headed hydraulic press 14, enabling the subsequent components to move under the drive of the double-headed hydraulic press 14. Two protective plates 15 are fixedly connected inside the base 13, preventing lubricant from damaging the double-headed hydraulic press 14. A top plate 16 is fixedly connected inside the base 13, cooperating with the base 13 to support and protect related components.

[0038] The two fixed brackets 1 are slidably connected at opposite ends to the adjacent ends of the insert plate 4, which provides guidance and fixation for the fixed brackets 1. The interiors of the two fixed brackets 1 are slidably connected to the exterior of the fixed plate 3, which prevents the fixed brackets 1 from shifting. The bottom end of the clamping plate 6 contacts the top end of the support plate 5, which provides support for the clamping plate 6 and increases stability. The moving frame 2 has a groove inside, which provides an installation position for the fixed brackets 1 and improves the stability between related components. The rear limiting plate 10 has two liquid outlet channels inside, which allow lubricant to flow out stably.

[0039] The guide block 11 has a guide groove inside, which can evenly spread the lubricant. The bottom end of the top plate 16 is slidably connected to the bottom end of the motion frame 2, and the top plate 16 can provide support for the sliding of the motion frame 2. The top plate 16 has a sliding groove inside, which can guide the movement of the drive block 17. The front and rear ends of the drive block 17 are slidably connected to the adjacent ends of the two limiting plates 10, which can limit the drive block 17 and prevent the drive block 17 from deviating. The base 13 is slidably connected to the outside of the slider 12. The structural design of the slider 12 is coupled with the sliding groove inside the base 13, which can limit the movement of the relevant components without affecting their movement.

[0040] Working principle: When the worker needs to process the pin, the appropriate clamping plate 6 is selected according to the size and shape of the pin, the fixing frame 1 is inserted into the inside of the moving frame 2, and the fixing frame 1 slides downward outside the insertion plate 4. At the same time, the fixing frame 1 drives the clamping plate 6 to slide downward outside the fixing plate 3. When the bottom end of the clamping plate 6 contacts the top end of the support plate 5, the installation of the clamping plate 6 is completed.

[0041] When clamping begins, the double-head hydraulic press 14 is started. The double-head hydraulic press 14 drives the drive block 17 to slide left and right inside the base 13. The drive block 17 drives the motion frame 2 to slide left and right at the top of the top plate 16. At the same time, the motion frame 2 drives the fixed frame 1 and the clamping plate 6 to move left and right, thus completing the clamping of the pin.

[0042] When the drive block 17 needs lubrication, the push hydraulic press 7 is started. The push hydraulic press 7 drives the push plate 8 to slide back and forth inside the base 13. At the same time, the push plate 8 slides at the close end of the two sealing plates 9, pushing the lubricant into the outlet channel of the limiting plate 10. The lubricant enters the guide groove of the guide block 11 through the outlet channel. The guide block 11 spreads the lubricant evenly under the drive of the drive block 17. At the same time, the drive block 17 drives the slider 12 inside the base 13 to avoid displacement.

[0043] 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.
