Description

Technical Field

[0001] This utility model relates to machining equipment, and in particular to a simple cutting machine support that can feed linearly. Background Technology

[0002] In machining and other fields, cutting equipment such as angle grinders are widely used. However, when operated by hand, the linear feed stability is poor, easily leading to problems such as cutting trajectory deviation and uneven cuts, affecting processing quality and posing safety hazards. Although existing cutting machine supports attempt to solve this problem, they generally suffer from the core pain points of low linear feed guidance accuracy and insufficient stability. They are also often accompanied by defects such as complex structure, poor adaptability, and unreliable workpiece fixation, failing to meet the actual needs of precise linear cutting. There is an urgent need to develop a simple cutting machine support with high linear feed accuracy. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a simple cutting machine support with linear feed capability, which achieves the technical effects of improving the stability of linear feed, simplifying the structure, and enhancing adaptability.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a simple cutting machine support with linear feed, including a base, a linear slide rail device and an angle grinder rotating arm. The base is a rectangular plate with rubber anti-slip pads at the bottom.

[0005] The linear slide rail device consists of a guide slide rail, a bearing bracket, and bearings. The bearing bracket consists of a vertical positioning plate and a horizontal connecting plate. The guide slide rail is set parallel to the long side of the base. Two bearing brackets are fixed to the two sides of one corner of the base by bolts. Each bearing bracket is equipped with two sets of four bearings that are parallel to each other. The guide slide rail is pressed down by the four upper bearings, while the four lower bearings provide support. The eight bearings form the movable track of the guide slide rail.

[0006] The guide rail has an I-shaped opening on its inner end facing the base for mounting the angle grinder's rotating arm. The angle grinder's rotating arm consists of a spring plate and a fixed plate. The spring plate is located near the guide rail, and its outer side has a cylindrical hole for bolt installation into the I-shaped opening. The angle between the spring plate and the angle grinder is an obtuse angle. A spring rod is vertically mounted on the spring plate, with a ring at its upper end and a spring fitted on the ring. The other end of the spring is fixed to the upper surface of the guide rail. The fixed plate has through holes for mounting bolts, which are used to fix the angle grinder. The angle grinder is equipped with matching threaded holes.

[0007] The angle grinder has a cutting groove under its rotating arm, which is located near the edge of the base and moves in the same direction as the angle grinder blade.

[0008] A superior technical solution involves a workpiece clamping strip on the base. The clamping strip is parallel to the cutting groove, and its two ends are screwed onto the base by two clamping bolts. The workpiece is completely fixed by the clamping strip, preventing movement or lifting during the cutting process, thus reducing cutting deviations and safety risks (such as saw blade breakage or workpiece flying out).

[0009] A superior technical solution features a limiting rod at one end of the guide rail, with a 150° angle between the spring plate and the fixed plate. This conforms to an ergonomic operating posture, reducing hand fatigue during prolonged operation, while also ensuring more even force distribution on the angle grinder and a smoother cutting process.

[0010] This utility model has the following advantages: 1. Simple structure, using ordinary plates and standard parts for assembly, resulting in low processing and maintenance costs and convenient assembly and disassembly; 2. Eight bearings constrain the slide rail to achieve stable linear feed, rolling friction reduces resistance, and spring rods buffer the reaction force and assist in fitting the workpiece, ensuring both cutting accuracy and labor saving; 3. Bolt-tightened angle grinders are easy to replace and maintain, and the cutting groove matches the trajectory, with many details reducing operational risks; 4. Adaptable to conventional angle grinders and plate cutting scenarios, with strong versatility, meeting the low-cost and practical needs of small-scale processing / DIY. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Furthermore, the accompanying drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the purpose of illustrating the embodiments of this utility model. Example 1

[0017] like Figure 1 , 2 As shown, Figure 1 The dashed line structure represents the angle grinder and the workpiece. The dashed line in the figure represents the angle grinder. A simple cutting machine support with linear feed includes a base 1, a linear slide rail device, and an angle grinder rotating arm. The base 1 is a rectangular plate with rubber anti-slip pads on the bottom.

[0018] The linear slide rail device consists of a guide rail 2, a bearing bracket 3, and bearings 4. The bearing bracket consists of a vertical positioning plate and a horizontal connecting plate. The guide rail 2 is set parallel to the long side of the base 1. Two bearing brackets 3 are respectively fixed to the two sides of one corner of the base 1 by bolts. Each bearing bracket 3 is provided with two sets of four bearings 4 that are parallel to each other. Multiple sets of rotating shafts are supported on the positioning plate of the bearing bracket 3 through the bearings 4. The guide rail 2 passes between the two sets of vertical bearings 4. The four bearings 4 at the upper end press against the upper surface of the guide rail 2, while the four bearings 4 at the lower end form the support of the guide rail 2. The eight bearings 4 form the movable track of the guide rail 2. The guide rail 2 can move in a certain direction in the horizontal direction without deviating.

[0019] A limiting rod 5 is provided at one end of the outer side of the guide slide rail 2. An I-shaped opening 6 is provided at the end of the guide slide rail 2 facing the inner side of the base for installing the rotating arm of the angle grinder. The rotating arm of the angle grinder consists of a spring plate 7 and a fixing plate 8. The spring plate 7 is located on the side closer to the guide slide rail 2. The outer side of the spring plate 7 has a cylindrical hole, which is bolted into the I-shaped opening to serve as the rotation center of the entire rotating arm. The included angle between the spring plate 7 and the fixing plate 8 is 150°. A spring rod 9 is vertically provided on the spring plate 7. A ring is provided at the upper end of the spring rod 9, and a spring 10 is fitted on the ring. The other end of the spring 10 is fixed to the upper surface of the guide slide rail 2 to provide the restoring force of the rotating arm. The fixing plate 8 has a through hole for installing bolts 801. Bolts 801 are used to fix the angle grinder 11. The angle grinder 11 is equipped with a matching threaded hole.

[0020] A cutting groove 12 is provided under the rotating arm of the angle grinder, and the cutting groove 12 is located near the edge of the base 1. The cutting groove 12 is consistent with the movement trajectory of the angle grinder blade. The base 1 is also equipped with a workpiece clamping strip 13, which is parallel to the cutting groove 12. The two ends of the clamping strip 13 are screwed onto the base by two clamping bolts 14. The workpiece 15 is completely fixed by the clamping strip, and there will be no movement or lifting during the cutting process, which reduces cutting deviation and safety risks (such as saw blade breakage or workpiece flying out).

[0021] The core working logic of this cutting machine support is "positioning-guiding-elastic feed-precise cutting".

[0022] In the initial state, the cutting machine 11 is placed vertically upwards, the thin handle is installed near the spring 10, the spring 10 is in a retracted state to reduce the impact of deformation performance, the thick handle is vertically upwards, and the cutting machine 11 is in its original position.

[0023] The procedure is as follows: First, place the workpiece 15 at the desired cutting position under the cutting blade of the angle grinder 11 and adjust the cutting position. Secure it by tightening the clamping bolts 14 at both ends of the pressure strip 13. Align the workpiece 15 with the cutting groove 12 on the edge of the base to calibrate the cutting trajectory. Secure the angle grinder 11 to the rotating arm using the bolts 801 on the fixing plate 8 (normally, the angle grinder 11 is always fixed on the rotating arm 7). Press down on the angle grinder 11. The spring rod 9 and spring 10 of the rotating arm of the angle grinder form an elastic structure. The spring 10 extends, and the angle grinder enters normal cutting. After the workpiece is cut, release the cutting machine handle. The spring 10 retracts, quickly pulling the cutting machine back, ensuring that the angle grinder can quickly detach from the workpiece and improving safety.

[0024] During cutting, the linear guide rail device provides precise guidance. The guide rail 2 is parallel to the long side of the base 1. The upper and lower eight sets of bearings 4 of the bearing bracket 3 form a constraint track. The resistance is reduced by rolling friction. Pushing the guide rail 2 can drive the angle grinder 11 to feed linearly. The bearing bracket 3 ensures the straightness of the trajectory. The spring 10 continuously provides elastic support to ensure that the blade fits the workpiece. The operator controls the feed speed to complete a smooth cut. The cutting groove avoids the blade trajectory, avoids damage to the base, and helps to predict the cutting position.

[0025] After cutting, the restoring force provided by the spring 10 to the rotating arm can pull the cutting machine 11 back to vertical and upward, and the cutting machine returns to its original position.
