Description

Technical Field

[0001] This utility model relates to the field of tooling technology, specifically to a tooling for fixing iron accessories. Background Technology

[0002] like Figure 3 The diagram shown is a schematic of an arched iron accessory, with its central section arching upwards and mounting holes drilled on both sides. (The diagram is incomplete and requires further context.) Figure 3 When processing iron accessories, they need to be fixed and holes need to be drilled on both sides. Therefore, a fixing fixture is needed to fix the iron accessories. However, the following problems generally exist when fixing arched iron accessories: (1) Generally, the iron accessories are pressed tightly onto the fixture table by a clamping device, but since the iron accessories are arched, the clamping device is easy to crush the arched part; (2) Since the length of the iron accessories is different, the current fixture is difficult to fix iron accessories of different lengths, and the adaptability is low; (3) Drill holes at both ends of the iron accessories by a drill bit, but the bottom surface of the iron accessories is generally the fixture table, and the drill bit is easy to come into contact with the fixture table during the drilling process, which can easily damage the fixture table or the drill bit. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a tooling for fixing iron accessories to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A fixture for fixing iron accessories includes a base, a central seat fixed at the center of the base, and sliding blocks slidably disposed on both sides of the central seat on the base, with the two sliding blocks being equidistant from the central seat. The base is also provided with a drive mechanism for driving the two sliding blocks to move simultaneously relative to each other or in opposite directions. Support seats are detachably connected to both sliding blocks, and grooves are formed on the top surface of the support seats. A cylinder is fixed on the central seat, and a support block with an arc-shaped top surface is detachably connected to the telescopic end of the cylinder. An outwardly extending extension plate is fixed on the opposite sides of the upper end of the two support seats, and a sliding hole is formed on the extension plate. A screw is slidably connected in the sliding hole, and a pressure plate extending towards the support block is connected to the upper end of both screws. A fastening mechanism is installed on the screw to fix the screw in the sliding hole.

[0006] Preferably, the driving mechanism includes bearing seats connected to both ends of the base, a lead screw rotatably connected to the two bearing seats, guide rails located on the base and on both sides of the lead screw, and a motor installed at one end of the base and connected to the lead screw for transmission. The lead screw has reverse threads on both sides, and two slide blocks are threadedly connected to both sides of the lead screw. The two slide blocks are slidably connected to the guide rails on both sides of the center seat. The middle part of the lead screw is rotatably connected to the center seat through a rotary bearing.

[0007] The above technical solution involves starting the motor and driving the lead screw to rotate, which in turn drives the two slides to move relative to or in opposite directions to accommodate iron accessories of different lengths and improve adaptability.

[0008] Preferably, the top surface of the slide is connected to a positioning post, and the bottom surface of the support base is provided with a positioning groove that matches the positioning post.

[0009] The above technical solution requires different drilling positions due to the different lengths or widths of the iron accessories. The support base is installed on the slide through the cooperation of the positioning groove and the positioning post. Therefore, the support base with different lengths or widths of grooves can be replaced according to the model of the iron accessory so that the drill bit can be inserted into the groove after drilling.

[0010] Preferably, the telescopic end of the cylinder is provided with an external spline, the bottom of the support block is connected to a connecting sleeve, the connecting sleeve is provided with an internal spline, and the telescopic end of the cylinder is connected to the spline of the connecting sleeve.

[0011] The above technical solution allows for the replacement of different models of support blocks based on the curvature or height of the iron accessories, since the telescopic end of the cylinder is connected to the connecting sleeve via a spline.

[0012] Preferably, the fastening mechanism consists of two nuts threaded onto the screw, with the two nuts located on the upper and lower sides of the extension plate, respectively.

[0013] The above technical solution involves loosening the two nuts on the screw, allowing the screw to slide within the sliding hole. When the pressure plate reaches above both ends of the iron accessory, the screw is pushed downwards to press the pressure plate tightly against the outer edge of the iron accessory end. Then, the two nuts are tightened to press the two ends of the iron accessory firmly, thus stabilizing it.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) Place both ends of the iron accessory on the support base, then control the cylinder to extend, drive the support block to rise, and abut against the bottom surface of the arched surface of the iron accessory to support the iron accessory and prevent it from collapsing. Then, press the edges of both ends of the iron accessory tightly onto the support base through the two pressure plates, so that the iron accessory can remain stable.

[0016] (2) Moreover, the two slides can be controlled to move relative to each other or in opposite directions at the same time through the drive mechanism, and the distance between the two slides and the center seat is the same. Therefore, after the two slides move the same distance at the same time, they can be adapted to iron accessories of different lengths, thus improving adaptability.

[0017] (3) When drilling, the pressure plate only presses on the edge of the iron accessory. The top surface of the support seat has a groove. The drill bit will not directly contact the support seat, but will enter the groove, thereby reducing damage to the support seat and the drill bit. Attached Figure Description

Detailed Implementation

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

[0023] Example 1

[0024] Please see Figure 1 and Figure 2 A fixture for fixing iron accessories includes a base 1, a central seat 2 fixed at the center of the base 1, and sliding blocks 3 slidably disposed on both sides of the central seat 2 on the base 1. The distances of the two sliding blocks 3 to the central seat 2 are the same. The base 1 is also provided with a drive mechanism for driving the two sliding blocks 3 to move simultaneously relative to each other or in opposite directions. Specifically, the drive mechanism includes bearing seats 12 connected to both ends of the base, a lead screw 13 rotatably connected to the two bearing seats, guide rails 14 disposed on the base and located on both sides of the lead screw, and a motor 15 installed at one end of the base and driven by the lead screw. The lead screw 13 has reverse threads on both sides. The two sliding blocks 3 are respectively threaded to both sides of the lead screw 13. The two sliding blocks 3 are slidably connected to the guide rails 14 on both sides of the central seat. The middle part of the lead screw 13 is rotatably connected to the central seat 2 through a rotary bearing. When the motor 15 is started, the lead screw 13 is rotated, which can drive the two slides 3 to move relative to or in opposite directions. Since the two slides 3 are equidistant from the center seat 2, after the two slides 3 move at the same speed, the distance from the two slides 3 to the center seat 2 is the same, thus enabling them to accommodate iron accessories of different lengths and improving adaptability.

[0025] Both slides 3 are detachably connected to support seats 4. Specifically, the top surface of the slide 3 is connected to a positioning post 16, and the bottom surface of the support seat 4 is provided with a positioning groove that matches the positioning post 16. Because the length or width of the iron accessories are different, the required drilling positions are also different. The support seat is installed on the slide through the cooperation of the positioning groove and the positioning post. Therefore, according to the model of the iron accessory, support seats with grooves of different lengths or widths can be replaced so that the drill bit can be inserted into the groove after drilling.

[0026] The top surface of the support base 4 has a groove 5, and a cylinder 6 is fixed on the central base 2. The telescopic end of the cylinder 6 is detachably connected to a support block 7 with an arc-shaped top surface. The telescopic end of the cylinder 6 has an external spline, and the bottom of the support block 7 is connected to a connecting sleeve 17 with an internal spline. The telescopic end of the cylinder 6 is splinedly connected to the connecting sleeve 17. The two ends of the iron accessory are placed on the support base 4, and then the cylinder 6 is extended to raise the support block 7, which then rests against the bottom surface of the arched surface of the iron accessory to support it and prevent it from collapsing. Since the curvature or height of the iron accessory varies, and the telescopic end of the cylinder 6 is splinedly connected to the connecting sleeve 17, different models of support blocks 7 can be replaced according to the curvature or height of the iron accessory.

[0027] On opposite sides of the upper ends of the two support bases 4, outwardly extending extension plates 8 are fixed. Sliding holes 9 are provided on the extension plates 8, and screws 10 are slidably connected within the sliding holes 9. The upper ends of both screws 10 are connected to pressure plates 11 extending towards the support block 7. Fastening mechanisms are installed on the screws 10 to fix them within the sliding holes 9. The fastening mechanisms consist of two nuts 18 threaded onto the screws 10, located on the upper and lower sides of the extension plates 8, respectively. Loosening the nuts 18 allows the screws 10 to slide within the sliding holes 9. When the pressure plates 11 reach above both ends of the iron accessory, the screws 10 are pushed downwards, causing the pressure plates 11 to press tightly against the outer edges of the iron accessory ends. Tightening the nuts then presses the iron accessory ends together, stabilizing it.

[0028] The working principle of this embodiment is as follows: The two ends of the iron attachment 18 are placed on the support base 4. Then, the cylinder 6 is extended, causing the support block 7 to rise and abut against the bottom surface of the arched surface of the iron attachment 18, thus supporting the iron attachment and preventing it from collapsing. Then, two pressure plates 11 press the edges of the two ends of the iron attachment tightly against the support base 4, thereby maintaining the stability of the iron attachment. Furthermore, the drive mechanism can control the two sliding blocks 3 to move simultaneously or in opposite directions to accommodate iron attachments of different lengths, improving adaptability. During drilling, the pressure plate 11 only presses on the edge of the iron attachment. The top surface of the support base 4 has a groove 5, so the drill bit does not directly contact the support base 4 but enters the groove 5, thereby reducing damage to the support base and the drill bit.
