Description

Technical Field

[0001] This utility model relates to a clamp for easy positioning in railing processing, belonging to the field of railing technology. Background Technology

[0002] A railing is a protective structure made of wood, metal, or other materials that surrounds spaces such as platforms, stairs, and railings, serving both a barrier and auxiliary function. Railings are widely used in architecture, transportation, landscaping, and other fields.

[0003] During the processing of railings, they need to be clamped and positioned. However, due to the different application scenarios and sizes of the railings, if the spacing of the clamps cannot be adjusted synchronously with the size of the railings, some railings may not be firmly clamped and fixed by the clamps. In this case, the force applied to the workpiece by the cutting tool during machining will cause the railings to shift, thus affecting the dimensional accuracy of the machining. For example, during operations such as cutting and drilling, the movement of the railings will lead to problems such as inaccurate cutting length and drilling position deviation, making it inconvenient for operators to use.

[0004] To address this, a fixture for easy positioning in railing processing is proposed. Utility Model Content

[0005] In view of this, the present invention provides a clamp for railing processing that is easy to position, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model is implemented as follows: A clamp for easy positioning of railing processing includes a work box, a support frame fixedly installed on the top of the work box, a cylinder fixedly installed on the top of the support frame, a drilling device fixedly installed on the bottom of the cylinder, a clamping mechanism provided on the surface of the work box, the clamping mechanism including a motor and connecting rods, four connecting rods are all located in the inner cavity of the work box, mounting blocks are movably connected to the outer sides of the four connecting rods, fixing rods are fixedly installed on the outer sides of two mounting blocks, moving blocks are fixedly installed on the tops of two fixing rods, L-shaped rods are fixedly installed on the tops of two moving blocks, and clamping plates are fixedly installed on the inner sides of two L-shaped rods.

[0007] More preferably, the motor is fixedly installed on the front side of the work box, and the output end of the motor is fixedly connected to a bidirectional screw. Both the front and rear sides of the surface of the bidirectional screw are threaded with screw blocks, and the four connecting rods are movably connected to the left and right sides of the two screw blocks.

[0008] More preferably, protective pads are glued to the inner surfaces of both clamps with PP adhesive, and both protective pads are made of rubber.

[0009] More preferably, the top of the work box is provided with sliding grooves on both the left and right sides, and the bottom sides of the two clamping plates are slidably connected to the inner cavities of the four sliding grooves.

[0010] More preferably, the top of the work box has movable slots on both the left and right sides, and the two movable blocks are slidably connected in the inner cavities of the two movable slots.

[0011] More preferably, a limiting rod is fixedly installed in the inner cavity of the working box, and the inner surfaces of the two screw blocks are slidably connected to the surface of the limiting rod.

[0012] More preferably, the left side of the work box has a slot, and the left side of the work box is connected to a maintenance door by bolts and threads.

[0013] More preferably, mounting plates are fixedly installed on both the front and rear sides of the bottom of the work box, and anchor bolts are threaded onto the left and right sides of the surfaces of the two mounting plates.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model, by setting up a clamping mechanism, uses the output of a motor to drive the connecting rod to swing, thereby causing the mounting block to move the clamping plate inward, thus clamping and positioning the railing. This effectively prevents the railing from shifting due to contact with the processing equipment during processing, which would affect the support processing of the railing, ensuring the stability of the railing during processing and making it convenient for operators to use.

[0016] II. This utility model, by setting protective pads, can prevent the clamping plates from scratching the surface of the railings when clamping them. By setting sliding grooves, the movement of the clamping plates can be limited to prevent them from shifting and affecting the clamping of the railings. By setting moving grooves, the movement of the moving blocks can be limited to prevent them from shifting and affecting the normal clamping of the railings. By setting limiting rods, the movement of the screw blocks can be limited to prevent them from rotating synchronously with the bidirectional screw, thus affecting the positioning of the railings. By setting maintenance doors and slots, maintenance and repair of the components inside the work box can be easily carried out, ensuring the convenience of maintenance. By setting anchor bolts, the overall equipment can be stabilized to prevent the entire equipment from tipping over due to accidental collisions, thus affecting the processing of the railings.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model embodiment provides a railing processing fixture for easy positioning, including a work box 1. A support frame 3 is fixedly installed on the top of the work box 1, and a cylinder 4 is fixedly installed on the top of the support frame 3. A drilling device 5 is fixedly installed on the bottom of the cylinder 4. A clamping mechanism 2 is provided on the surface of the work box 1. The clamping mechanism 2 includes a motor 201 and connecting rods 204. All four connecting rods 204 are located in the inner cavity of the work box 1. Mounting blocks 205 are movably connected to the outer sides of the four connecting rods 204. Fixing rods 206 are fixedly installed on the outer sides of two mounting blocks 205. Moving blocks 207 are fixedly installed on the top of two fixing rods 206. L-shaped rods 208 are fixedly installed on the top of two moving blocks 207. Clamping plates 209 are fixedly installed on the inner sides of two L-shaped rods 208. The motor 201 is fixedly installed on the work box 1. On the front side, the output end of the motor 201 is fixedly connected to a bidirectional screw 202. Both the front and rear sides of the surface of the bidirectional screw 202 are threaded with screw blocks 203. Four connecting rods 204 are movably connected to the left and right sides of two screw blocks 203. The inner surfaces of the two clamping plates 209 are glued with protective pads 210 by PP glue. The material of the two protective pads 210 is rubber. The top left and right sides of the work box 1 are provided with sliding grooves 211. The bottom front and rear sides of the two clamping plates 209 are slidably connected to the inner cavities of the four sliding grooves 211. The top left and right sides of the work box 1 are provided with moving grooves 212. Two moving blocks 207 are slidably connected to the inner cavities of the two moving grooves 212. A limit rod 213 is fixedly installed in the inner cavity of the work box 1. The inner surfaces of the two screw blocks 203 are slidably connected to the surface of the limit rod 213.

[0029] By setting up the clamping mechanism 2, the screw block 203 drives the connecting rod 204 to swing through the output of the motor 201, thereby causing the mounting block 205 to move the clamping plate 209 inward. This clamps and positions the railing, effectively preventing the railing from shifting due to contact with the processing equipment during processing, thus ensuring the stability of the railing during processing and making it convenient for operators to use. By setting up the protective pad 210, the clamping plate 209 can be prevented from scratching the surface of the railing when clamping it. By setting the sliding groove 211, the movement of the clamping plate 209 can be limited to prevent the clamping plate 209 from deviating during movement, thus affecting the clamping work of the railing. By setting the moving groove 212, the movement of the moving block 207 can be limited to prevent the moving block 207 from deviating during movement, thus affecting the normal clamping work of the railing. By setting the limiting rod 213, the movement of the screw block 203 can be limited to prevent the screw block 203 from rotating synchronously with the bidirectional screw 202 during movement, thus affecting the positioning work of the railing.

[0030] Example 2

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, a slot 6 is provided on the left side of the work box 1, and a maintenance door 7 is connected to the left side of the work box 1 by bolt thread. Mounting plates 8 are fixedly installed on the front and rear sides of the bottom of the work box 1, and anchor bolts 9 are threadedly connected to the left and right sides of the surfaces of the two mounting plates 8.

[0032] By setting up maintenance doors 7 and slots 6, it is convenient to carry out maintenance and repair work on the parts inside the working box 1, ensuring the convenience of maintenance of the parts inside the working box 1. By setting up anchor bolts 9, the overall equipment can be stabilized, preventing the equipment from tipping over due to accidental collisions, which would affect the processing of the railing.

[0033] When this utility model is in operation: First, the railing is placed inside the clamping plate 209. Then, through the output of the motor 201, the bidirectional screw 202 rotates, causing the screw block 203 to move outward. At this time, the screw block 203 and the connecting rod 204 cooperate with each other, causing the mounting block 205 to pull the fixing rod 206 to move inward. At this time, the fixing rod 206 simultaneously drives the moving block 207 and the L-shaped rod 208 to move inward, and causes the clamping plate 209 to move inward synchronously. The clamping plate 209 clamps the railing. Then, the extension drilling device 5 of the cylinder 4 drills holes in the railing downward, thereby completing the processing of the railing.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
