Description

Technical Field

[0001] This utility model relates to a tooling fixture, specifically a fixture for processing a flywheel housing to prevent slippage, and belongs to the field of machining technology. Background Technology

[0002] The flywheel housing is installed on the outside of the flywheel to cover it and provide safety protection. The flywheel housing has a stop surface and a body surface. The stop surface of the flywheel housing mates with the engine to cover the flywheel, and the body surface of the flywheel housing mates with the clutch.

[0003] In the prior art, such as the flywheel housing large stop end face hole system and scribing fixture disclosed in announcement number CN202120347750.1, the flywheel housing is mounted on the upper surface of the mounting frame, the clamping plate fixes the flywheel housing, the anti-slip pad prevents the flywheel housing from loosening, the slide block slides in the slide groove, allowing the position of the flywheel housing to be finely adjusted, and it can clamp flywheel housings of different sizes; the telescopic column extends and retracts in the buffer groove, improving the stability of the slide block movement, the buffer spring gives the slide block an excellent buffering effect, and the limiting edge slides into the limiting groove to prevent the slide block from falling off; the above-mentioned prior art solution The following shortcomings exist: When clamping the flywheel housing, the fixture relies solely on friction to prevent the workpiece from slipping, lacking an effective anti-slip mechanical structure. During long-term use, as the fixture surface wears and the workpiece surface condition changes (such as oil stains and chips adhering during processing), the friction will gradually decrease, further reducing the fixture's anti-slip performance. This may cause the flywheel housing to loosen and slip during processing, which will not only damage the quality of the processed surface, causing surface scratches, dimensional deviations, and other problems, but may also lead to safety accidents, posing a threat to the personal safety of operators. Utility Model Content

[0004] The purpose of this utility model is to provide a non-slip flywheel housing processing fixture in order to solve at least one of the above-mentioned technical problems.

[0005] The present invention achieves the above objectives through the following technical solution: a jig for processing a flywheel housing with anti-slip properties, comprising a base;

[0006] A clamping assembly is installed on the surface of the base. The clamping assembly includes a fixing frame that is evenly fixed in a ring on the surface of the base. A guide rod is slidably connected in a through hole on the surface of the fixing frame. A clamping arc plate is installed at one end of the guide rod. A cylinder is fixed on the bottom surface of the base. The piston end of the cylinder is connected to a cone top set on the surface of the base. One end of the guide rod abuts against one side surface of the cone top.

[0007] As a further improvement of this utility model: the bottom surface of the tightening arc plate is integrally formed with an anti-slip support plate, and both the surface of the tightening arc plate and the anti-slip support plate are provided with anti-slip textures.

[0008] As a further embodiment of this utility model: a spring is sleeved on the surface of the guide rod, one end of the spring abuts against one side of the fixing frame, and the other end of the spring abuts against a fixing retaining ring integrally formed on the surface of the guide rod.

[0009] As a further embodiment of this utility model: a pressure-fixing assembly is installed on the surface of the base. The pressure-fixing assembly includes a fixed bracket fixed to the surface of the base. A threaded sleeve is rotatably connected to the bottom surface of the fixed bracket. A hinge block is threadedly connected to the surface of the threaded sleeve. A hinge rod is hinged to the surface of the hinge block. An anti-slip pressure plate is hinged to the other end of the hinge rod.

[0010] As a further embodiment of this utility model: a guide block is integrally formed on one side of the anti-slip pressure plate, a fixed guide plate is fixed on one side of the top clamping arc plate, and the guide block is slidably connected in a guide groove opened on the surface of the fixed guide plate.

[0011] As a further embodiment of this utility model: a fixing rod is fixed to the surface of the cone top, a spiral groove is provided on the outer side of the fixing rod, and a sliding protrusion is integrally formed inside one end of the threaded sleeve. The threaded sleeve is slidably connected to the surface of the fixing rod through the sliding protrusion and the spiral groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a clamping assembly, in which multiple clamping arc plates are simultaneously clamped against the inner circular surface of the flywheel housing to achieve initial positioning and fixation of the flywheel housing. The contact between the multiple clamping arc plates and the inner circular surface of the flywheel housing can provide multi-dimensional positioning support. Compared with traditional fixtures with a single or few positioning points, this method can more accurately determine the position of the flywheel housing in the fixture. The simultaneous clamping of multiple clamping arc plates against the inner circular surface of the flywheel housing forms a multi-point friction and support system, which can effectively resist the component of cutting force in different directions and prevent the flywheel housing from slipping or rotating in the fixture.

[0014] The anti-slip support plate can support and limit the bottom of the fixed flywheel housing, greatly improving the reliability and stability of anti-slip. It can ensure that the flywheel housing will not change shape while being firmly fixed, and ensure that the dimensional accuracy after processing meets the requirements.

[0015] 2. This utility model is equipped with a pressure-fixing component, which causes the anti-slip pressure plate to press against the surface of the flywheel housing, providing additional fixing force to prevent the flywheel housing from shifting or vibrating under the action of cutting force. The pressure of the anti-slip pressure plate can effectively suppress such displacement and vibration, keeping the flywheel housing in a more stable state in the fixture, ensuring the smooth progress of the machining process, avoiding damage to the machined surface and dimensional deviations caused by workpiece loosening, and reducing the risk of safety accidents that may be caused by workpiece slippage, thus providing a safer working environment for operators.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 1

[0023] like Figures 1 to 5 As shown, a jig for machining a flywheel housing to prevent slippage includes a base 1;

[0024] A clamping assembly 2 is installed on the surface of the base 1. The clamping assembly 2 includes a cylinder 21, a conical top 22, a fixing frame 23, a guide rod 24, a clamping arc plate 25, an anti-slip support plate 26, a spring 27, and a fixing retaining ring 28. The fixing frame 23 is evenly fixed to the surface of the base 1 in a ring. The guide rod 24 is slidably connected in the through hole opened on the surface of the fixing frame 23. The clamping arc plate 25 is installed at one end of the guide rod 24. The cylinder 21 is fixed to the bottom surface of the base 1. The piston end of the cylinder 21 is connected to the conical top 22 set on the surface of the base 1. One end of the guide rod 24 abuts against one side surface of the conical top 22.

[0025] This causes multiple clamping arc plates 25 to simultaneously clamp against the inner circular surface of the flywheel housing, achieving initial positioning and fixation of the flywheel housing. The contact between the multiple clamping arc plates 25 and the inner circular surface of the flywheel housing provides multi-dimensional positioning support. Compared with traditional fixtures with a single or few positioning points, this method can more accurately determine the position of the flywheel housing in the fixture. The simultaneous clamping of multiple clamping arc plates 25 against the inner circular surface of the flywheel housing forms a multi-point friction and support system, which can effectively resist the component forces of cutting force in different directions and prevent the flywheel housing from slipping or rotating in the fixture.

[0026] The bottom surface of the top-tightening arc plate 25 is integrally formed with an anti-slip support plate 26, and both the surface of the top-tightening arc plate 25 and the anti-slip support plate 26 are provided with anti-slip textures.

[0027] The anti-slip support plate 26, when used in conjunction with the fixed flywheel housing, can support and limit the bottom of the fixed flywheel housing, which greatly improves the reliability and stability of anti-slip. This not only ensures the smooth progress of the processing process and avoids damage to the processing surface and dimensional deviations caused by workpiece loosening, but also reduces the risk of safety accidents that may be caused by workpiece slippage, providing a safer working environment for operators.

[0028] A spring 27 is fitted on the surface of the guide rod 24. One end of the spring 27 abuts against one side of the fixing bracket 23, and the other end of the spring 27 abuts against the fixing retaining ring 28 integrally formed on the surface of the guide rod 24.

[0029] When the limiting fixation of the flywheel housing is released, the compressed spring 27 can cause the clamping arc plate 25 to move in the opposite direction to one side and disengage from the surface of the flywheel housing under its own elastic action, thereby causing the clamping arc plate 25 to reset. Example 2

[0030] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0031] A clamping assembly 3 is installed on the surface of the base 1. The clamping assembly 3 includes a fixed guide plate 31, a guide groove 32, a guide block 33, a fixed bracket 34, a hinge rod 35, an anti-slip pressure plate 36, a fixed rod 37, a spiral groove 38, a threaded sleeve 39, a hinge block 310, and a sliding protrusion 311. The fixed bracket 34 is fixed to the surface of the base 1. The bottom surface of the fixed bracket 34 is rotatably connected to the threaded sleeve 39. The surface of the threaded sleeve 39 is threadedly connected to the hinge block 310. The surface of the hinge block 310 is hinged to the hinge rod 35. The other end of the hinge rod 35 is hinged to the anti-slip pressure plate 36.

[0032] The anti-slip pressure plate 36 presses against the surface of the flywheel housing, providing additional fixing force to prevent the flywheel housing from shifting or vibrating under the action of cutting force. The pressure of the anti-slip pressure plate 36 can effectively suppress such displacement and vibration, keeping the flywheel housing in a more stable state in the fixture.

[0033] One side of the anti-slip pressure plate 36 is integrally formed with a guide block 33, and the other side of the pressing arc plate 25 is fixed with a fixed guide plate 31. The guide block 33 is slidably connected in the guide groove 32 opened on the surface of the fixed guide plate 31.

[0034] It can guide the moving anti-slip pressure plate 36, thereby improving the stability of the anti-slip pressure plate 36 during movement.

[0035] A fixing rod 37 is fixed to the surface of the cone top 22. A spiral groove 38 is provided on the outer side of the fixing rod 37. A sliding protrusion 311 is integrally formed inside one end of the threaded sleeve 39. The threaded sleeve 39 is slidably connected to the surface of the fixing rod 37 through the sliding protrusion 311 and the spiral groove 38.

[0036] Working principle: In use, the flywheel housing is first placed outside the multiple clamping arc plates 25 arranged in a ring. Then, by controlling the extension of the piston end of the cylinder 21, the cone apex 22 is moved upward and contacts one end of multiple guide rods 24. As the cone apex 22 moves upward, the multiple guide rods 24 can move to one side synchronously, which in turn causes the multiple clamping arc plates 25 to clamp against the inner circular surface of the flywheel housing at the same time, realizing the initial limiting and fixing of the flywheel housing. The contact between the multiple clamping arc plates 25 and the inner circular surface of the flywheel housing can provide multi-dimensional positioning support. Compared with traditional fixtures with a single or a few positioning points, this method can more accurately determine the position of the flywheel housing in the fixture. The multiple clamping arc plates 25 clamping against the inner circular surface of the flywheel housing at the same time form a multi-point friction and support system, which can effectively resist the component of cutting force in different directions and prevent the flywheel housing from slipping or rotating in the fixture.

[0037] The anti-slip support plate 26, when used in conjunction with the fixed flywheel housing, can support and limit the bottom of the fixed flywheel housing, which greatly improves the reliability and stability of anti-slip and ensures that the flywheel housing will not change shape while being firmly fixed, thus ensuring that the dimensional accuracy after processing meets the requirements.

[0038] As the cone apex 22 moves upward, the fixing rod 37 mounted on the surface of the cone apex 22 slides into the threaded sleeve 39. With the cooperation of the spiral groove 38 and the sliding protrusion 311, the threaded sleeve 39 can rotate on the bottom surface of the fixing bracket 34 as the fixing rod 37 slides into the threaded sleeve 39. This causes the hinge block 310, threaded onto the surface of the threaded sleeve 39, to move on the surface of the threaded sleeve 39. The hinge block 310 then moves downward to push against the hinge rod 35, thereby preventing slippage at one end of the hinge rod 35. The pressure plate 36 slides to one side, causing the anti-slip pressure plate 36 to press against the surface of the flywheel housing, providing additional fixing force to prevent the flywheel housing from shifting or vibrating under the action of cutting force. The pressure of the anti-slip pressure plate 36 can effectively suppress such displacement and vibration, keeping the flywheel housing in a more stable state in the fixture, ensuring the smooth progress of the machining process, avoiding damage to the machined surface and dimensional deviations caused by workpiece loosening, and reducing the risk of safety accidents that may be caused by workpiece slippage, providing a safer working environment for operators.
