Description

Technical Field

[0001] The invention relates to the technical field of fixtures and clamps, and in particular to a guide rail straightening device. Background Art

[0002] In the field of industrial automation and precision machinery, guide rails are key guiding and supporting components, and their accuracy and stability are crucial to the normal operation of mechanical equipment. Guide rails are usually used to support and guide sliding parts, such as the cutting head of a machine tool, the robotic arm of an automated production line, etc., to ensure that they move smoothly on a predetermined path.

[0003] Traditional guide rail straightening technology mainly relies on manual operation and simple mechanical devices. These methods often have problems such as low efficiency, low precision, and complex operation. For example, operators use tools such as hammers and pry bars to adjust the straightness of the guide rail by knocking and prying. This method relies on the experience and skills of the operator, the straightening effect is difficult to guarantee, and the labor intensity is high and the efficiency is low. There are also some more efficient methods, which mainly use laser measurement technology to detect the straightness of the guide rail through the reflection of the laser beam, and achieve straightening by adjusting the position of the guide rail. This method has high precision, but the equipment is expensive and has high requirements for environmental conditions. It is not suitable for all occasions. Summary of the invention

[0004] The object of the present invention is to provide a guide rail straightening device to improve the efficiency of straightening and reduce the operating difficulty and equipment cost.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a guide rail straightening device, comprising a base, wherein the front and rear ends of the base are respectively detachably connected to a support block, the top of the support block is provided with a positioning groove for placing the workpiece, the base is provided with a left slide rail and a right slide rail along the front and rear directions, the left slide rail and the right slide rail are respectively distributed on the left and right sides of the workpiece, the left slide rail is slidably connected to a detection device for detecting the curvature of the workpiece, and the right slide rail is slidably connected to a straightening mechanism for pushing the workpiece for straightening.

[0006] Preferably, the detection device comprises a left sliding block slidably connected to the left sliding rail and a dial indicator mounted on the left sliding block, and the position of the ejector pin of the dial indicator is adjustable so that it can abut against the left side of the workpiece.

[0014] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0015] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact through another feature between them.

[0016] like Figure 1As shown, a guide rail straightening device comprises a base 1, and a support block 2 is detachably connected to the front and rear ends of the base 1, and a positioning groove for placing a workpiece 3 is provided at the top of the support block 2. The base 1 is provided with a left slide rail 4 and a right slide rail 5 along the front and rear directions, and the left slide rail 4 and the right slide rail 5 are respectively distributed on the left and right sides of the workpiece 3. The left slide rail 4 is slidably connected to a detection device for detecting the curvature of the workpiece 3, and the right slide rail 5 is slidably connected to a straightening mechanism for pushing against the workpiece 3 for straightening. Those skilled in the art should know that usually a long strip of guide rail will only bend to one side, so it only needs to be pushed against and straightened on one side.

[0017] In the above structure, the detection device includes a left slider 6 slidably connected to the left slide rail 4 and a dial indicator 7 installed on the left slider 6 . The position of the ejector pin of the dial indicator 7 is adjustable so that it can abut against the left side of the workpiece 3 .

[0018] The straightening mechanism includes a right slider 8 slidably connected to the right slide rail 5 and an adjusting bolt 9 threadedly connected to the right slider 8. One end of the rod of the adjusting bolt 9 can be pushed against the right side of the workpiece 3 for straightening. This allows the straightening force to act directly on the workpiece, improving the accuracy and effectiveness of the straightening. The adjusting bolt 9 is threadedly connected to the right slider 8, so that the magnitude of the straightening force can be accurately controlled by rotating the adjusting bolt, which is easy to operate and easy to achieve fine adjustment, thereby improving the flexibility and accuracy of the straightening.

[0019] Among them, the head of the adjusting bolt 9 is fixedly connected with a knob block 10, and the outer wall surface of the knob block 10 is provided with a through hole in the radial direction, so that during the adjustment process, auxiliary tools such as a wrench or a pin can be used to insert into the pipe through hole, so as to facilitate the force and easily rotate the adjusting bolt 9, thereby speeding up the straightening process and improving work efficiency.

[0020] In this embodiment, the base 1 is provided with a plurality of mounting holes for mating with the support block 2 at intervals along its length. This allows the support block 2 to be flexibly mated with the base 1 to adapt to workpieces of different lengths, thereby improving the adaptability and flexibility of the device. The base 1 is provided with a strip-shaped positioning groove 11 along its length, and the bottom end of the support block 2 is provided with a positioning protrusion 12 (such as Figure 2 This ensures the stable positioning of the workpiece on the support block, prevents displacement during measurement and alignment, and improves the accuracy of measurement and alignment.

[0021] The guide rail straightening device provided in the above embodiment, in the specific straightening process, after the workpiece 3 is placed in the positioning grooves of the two support blocks 2, the position of the pin of the dial gauge 7 can be adjusted first, and the side of the workpiece 3 close to the positioning groove of the support block 2 is used as the reference position, which is usually straight, and then the dial gauge 7 is adjusted to zero with this as the reference for straightening, so that after the position of the sliding dial gauge 7 is adjusted, the reading of the dial gauge 7 can be observed to see if there is a deviation by adjusting its pin against the left side of the workpiece 3. When there is a deviation, the right slider 8 can be moved so that the adjusting bolt 9 is at that position, and then the adjusting bolt 8 is rotated to push and straighten from the right side of the guide rail. During the straightening process, the reading change of the dial gauge can be observed, and the reading can be returned to zero. In the actual straightening process, since the straightening can be performed by slightly turning the adjusting bolt 8, the operation strength and difficulty are not great, and the operator does not need to fix the left slider 6 and the right slider 8 on the corresponding slide rail, but can hold the left slider 6 with one hand and quickly turn the adjusting bolt 8 with the other hand, thereby ensuring sufficient straightening efficiency.

[0022] Since the long guide rails may bend to the other side, some guide rails need to be flipped 90 degrees and placed on the device for straightening. Therefore, the support block 2 in this embodiment is removable and replaced with another support block 2 to change the size of its top positioning groove so that it can adapt to the width of the flipped guide rail for subsequent straightening.

[0023] It can be seen from the above-mentioned straightening processing that the principle of the present invention is to use the detachable support block 2 on the base 1 to fix the guide rail, accurately detect the curvature of the guide rail by the dial indicator 7 on the left slide rail 4, and accurately straighten the guide rail by the adjusting bolt 8 on the right slide rail 5, which effectively improves the accuracy and efficiency of the guide rail straightening, reduces the operating difficulty and equipment cost, and at the same time enhances the flexibility and adaptability of the equipment, ensuring the straightness and quality of the workpiece.

[0024] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
