Description

Technical Field

[0001] This utility model relates to a polishing fixture for multi-core connectors in the field of optical fiber communication, and in particular a quick-release polishing fixture with pressure compensation. Background Technology

[0002] With the continuous development of the fiber optic communication industry, the demand for multi-core connectors is increasing, and the requirements for production efficiency are also rising. Users generally hope to use quick-release grinding fixtures to further improve grinding output. Conventional grinding fixtures usually fix the product by tightening the threads one turn at a time, which is labor-intensive and has low clamping efficiency.

[0003] Currently, there are some types of quick-release clamps on the market that use rigid positioning structures and achieve quick assembly and disassembly through the rigid self-locking of levers or cams. However, these structures generally suffer from significant wear, lack of compensation after wear, poor adaptability, and low stability, resulting in a short product lifespan. Furthermore, due to positioning limitations, when there are tolerance variations in products from different molds, the locking pressure applied to the product will vary greatly, leading to unstable product parameters after grinding (for example, the height of optical fibers is usually required to be at the nanometer level; unstable pressure causes deformation of the product in the clamp, which affects the grinding results).

[0004] Given the various shortcomings of existing technical solutions, there is an urgent need to propose a more optimized solution. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a quick-release grinding fixture with pressure compensation.

[0006] A pressure-compensated quick-release grinding fixture, comprising:

[0007] A clamp base, on which a fixing block is installed, and the fixing block is provided with an oblique hole at a first preset angle to the clamp base, and a pin is installed on one or both sides of the oblique hole;

[0008] A rotating sleeve includes a sleeve body and a knob connected to the top of the sleeve body; a pressing assembly is provided inside the cavity of the sleeve body, and a pressure block is provided at a position where the pressing assembly extends beyond the bottom of the sleeve body; the pressure block is used to contact a preset multi-core connector.

[0009] The sleeve body is inserted into the oblique hole after passing through a reset spring; when the knob is pushed and rotated to the second preset angle, the pressing component pushes the pressure block under the guidance of the pin, positioning and pressing the multi-core connector on the fixture base.

[0010] Preferably, one or more L-shaped grooves are formed on the outer wall of the sleeve body, and a protrusion matching the L-shaped groove is provided on the inner wall of the oblique hole; or, one or more L-shaped grooves are formed on the inner wall of the oblique hole, and a protrusion matching the L-shaped groove is provided on the outer wall of the sleeve body.

[0011] When the knob is pushed and rotated to the second preset angle, the protrusion slides from the starting point of the L-shaped groove to the ending point of the L-shaped groove.

[0012] Preferably, the fixing block is locked onto the fixture base by screws.

[0013] Preferably, there are multiple fixing blocks, which are evenly arranged on the fixture base.

[0014] Preferably, the clamp base is circular or square, and the plurality of fixing blocks are evenly arranged with the geometric center of the clamp base as the center.

[0015] Preferably, a device connection column is provided at the geometric center of the fixture base.

[0016] Preferably, the extrusion assembly includes a pressure rod, an extrusion spring, and a spring stop; the spring stop is disposed on the inner top of the sleeve body, the pressure rod has the pressure block at its front end, and the extrusion spring is disposed between the rear end of the pressure rod and the spring stop.

[0017] This utility model provides a pressure-compensated quick-release grinding fixture. During use, by pushing and rotating the rotating sleeve at a certain angle, the pressing component inside the rotating sleeve, guided by a pin, pushes the pressure block, positioning and clamping the multi-core connector onto the fixture base. When clamping the multi-core connector, the pressure rod retracts a certain distance due to the compression spring and spring baffle, ensuring consistent and stable clamping force. This also ensures stable pressure even with slight wear on components during long-term use. Furthermore, the return spring allows the rotating sleeve to return to its initial position when the knob is released, facilitating the next operation.

[0018] Compared with existing technologies, this technical solution achieves rapid assembly and disassembly while maintaining a stable and consistent clamping force on the product through pressure and positioning compensation. It has great compatibility and solves the problem of rapid assembly and disassembly in grinding multi-core products. At the same time, it can compensate for changes in clamping position / parameters caused by wear during long-term use, and has a long stable service life, solving the problems of short life and unstable clamping that are common in existing quick-assembly fixtures.

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] A quick-release grinding fixture with pressure compensation is provided, such as... Figures 1 to 4 As shown, it includes:

[0030] The fixture base 100 has a fixing block 102 installed on it. The fixing block has an oblique hole 103 at a first preset angle to the fixture base. A pin 104 is installed on one or both sides of the oblique hole.

[0031] The rotating sleeve 200 includes a sleeve body 201 and a knob 202 connected to the top of the sleeve body; a pressing assembly 300 is provided in the cavity of the sleeve body, and a pressure block 203 is provided at the position where the pressing assembly extends beyond the bottom of the sleeve body; the pressure block is used to contact a preset multi-core connector 204.

[0032] After passing through a return spring, the sleeve body is fitted into the oblique hole; when the knob is pushed and rotated to the second preset angle, the pressing component pushes the pressure block under the guidance of the pin, positioning and pressing the multi-core connector on the fixture base.

[0033] The fixture base can be round, square, or other shapes. The specific shape of the fixing block and the way it is fixed to the fixture base are not limited. For example, the fixing block can be locked from the side by screws 206 or by drilling screw holes in the top and locking it with screws.

[0034] The first preset angle ensures that the rotating sleeve is inserted into the inclined hole at a certain angle. The pressing component, guided by the pin, pushes the pressing block to move, thereby positioning and pressing the multi-core connector onto the fixture base. This locking scheme, which uses the pushing and rotating of the rotating sleeve to drive the pressing block to press the product, has pressure and positioning compensation functions. While achieving quick assembly and disassembly, it can maintain a stable and consistent clamping force on the product and has great compatibility.

[0035] Furthermore, the extrusion assembly includes a pressure rod 301, an extrusion spring 302, and a spring stop 303; the spring stop is disposed on the top inner side of the sleeve body, the front end of the pressure rod is provided with a pressure block, and the extrusion spring is disposed between the rear end of the pressure rod and the spring stop.

[0036] When locked, the pressure bar will retract a certain distance under pressure to ensure that the clamping force of the product is stable over a long period of time. It can compensate for changes in clamping position / parameters caused by wear during long-term use, and has a long stable service life, solving the problems of short service life and unstable clamping that are common in existing quick-release clamps.

[0037] Furthermore, one or more L-shaped grooves 205 are provided on the outer wall of the sleeve body; a protrusion matching the L-shaped groove is provided on the inner wall of the oblique hole (not visible in the figure); when the knob is pushed and rotated to the second preset angle, the protrusion slides from the starting point of the L-shaped groove to the ending point of the L-shaped groove.

[0038] During the movement of the sleeve body, the L-shaped groove and the protrusion cooperate to limit the rotation angle of the sleeve body, i.e., the second preset angle, thus serving as a limit travel. It can be understood that the configuration can also be reversed, with one or more L-shaped grooves formed on the inner wall of the inclined hole, and a protrusion matching the L-shaped grooves provided on the outer wall of the sleeve body; the effect is the same.

[0039] Furthermore, there are multiple fixing blocks, which are evenly arranged on the fixture base with the geometric center of the fixture base as the center, so as to facilitate the operation of multiple multi-core connectors.

[0040] Furthermore, a device connection post 400 is provided at the geometric center of the fixture base for device connection.

[0041] The above is a description of the quick-release grinding fixture with pressure compensation of this utility model, which is used to help understand this utility model. However, the implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of this utility model shall be considered as equivalent substitutions and shall be included within the protection scope of this utility model.
