Description

Technical Field

[0001] This utility model relates to a clamp, and more particularly to a tooling clamp for flange drilling. Background Technology

[0002] A flange, also known as a disc, is typically a disc-shaped metal body with several holes around its perimeter for connecting other components. Generally, a flange has a central shaft hole and bolt holes evenly distributed around its circumference. CNC drilling machines are typically used to drill the flange, which needs to be clamped with a fixture before drilling.

[0003] For example, a flange drilling fixture, disclosed in Chinese Patent Publication No. CN219310157U, belongs to the field of flange processing technology. It includes a base, a support shaft, and a drill jig. The base has a circular slot in the middle. The drill jig is disc-shaped, with multiple positioning holes evenly distributed along its circumference and a through hole at its center. Positioning plates are arranged on both sides of the drill jig in a radial direction away from the disc, and the positioning plates are detachably connected to the base. The support shaft is vertically arranged, with its lower end placed in the slot and its upper part passing through the through hole. Multiple flanges are fitted onto the support shaft between the drill jig and the base. The base has an annular groove along the outer circumference of the slot, and the positioning holes are projected downwards into the annular groove. This invention uses a support shaft to fit flanges, with the drill jig and base respectively positioned above and below, detachably connecting the drill jig and base. Bolts are used to connect the drill jig and base, allowing for simultaneous fixing of multiple flanges. During flange processing, this ensures the flanges remain stationary, avoiding processing errors.

[0004] Some problems were found when using the existing flange drilling fixture. First, the flange is placed directly on the base, and the drill rod needs to penetrate the flange during the drilling process, which will cause interference between the drill rod and the base. Second, the flange is sleeved on the support shaft. The through hole size of the center of the flange is different for different specifications. When the through hole is small, it is difficult to sleeve it on the support shaft, making it difficult for the device to adapt to the problem of clamping flanges of different specifications. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling fixture for flange drilling to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for drilling flanges, comprising a base and a flange to be processed, wherein an installation slide rail is embedded in the base, and a T-shaped slide groove is provided at the front end of the installation slide rail, wherein a first T-shaped slider and a second T-shaped slider are slidably installed in the T-shaped slide groove, positioning rods are symmetrically fixed on the base, a sliding rod is fixed on the first T-shaped slider, and a support ring is fixed on both the sliding rod and the positioning rod, a threaded rod is fixed on the second T-shaped slider, and a pressure plate is slidably sleeved on the threaded rod.

[0007] Preferably, the pressure plate has a through hole, which cooperates with the threaded rod.

[0008] Preferably, a fixing nut is threaded onto the threaded rod.

[0009] Preferably, the pressure plate has limit grooves at both ends, and a limit slider is slidably installed in the limit groove.

[0010] Preferably, a pressure head is fixedly connected to the other end of the limiting slider, and the pressure head cooperates with the flange to be processed.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The outer wall of the flange to be processed is pressed against the positioning rod between the two. Then, by moving the first T-shaped slider, the sliding rod is moved so that the first T-shaped slider also presses against the outer wall of the flange to be processed. Then, the pressure plate is tightened to move the pressure head down and fix the flange to be processed. This method can clamp and fix flanges of different sizes and specifications.

[0013] 2. By using the support rings on the positioning rod and sliding rod to lift the lower edge of the flange to be processed, the flange to be processed is suspended in the air, thus avoiding interference between the drill rod and the base during the drilling process.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a tooling fixture for drilling flanges, including a base 1 and a flange 7 to be processed. The base 1 is embedded with an installation slide rail 101. The front end of the installation slide rail 101 is provided with a T-shaped slide groove 102. A first T-shaped slider 3 and a second T-shaped slider 5 are slidably installed in the T-shaped slide groove 102. A positioning rod 2 is symmetrically fixed on the base 1. A sliding rod 301 is fixed on the first T-shaped slider 3. A support ring 4 is fixed on both the sliding rod 301 and the positioning rod 2. A threaded rod 501 is fixed on the second T-shaped slider 5. A pressure plate 6 is slidably sleeved on the threaded rod 501.

[0021] In this embodiment, a ring-shaped limiting mechanism is formed by symmetrically arranging positioning rods 2 and sliding rods 301. The outer wall of the flange to be processed 7 is pressed against the two positioning rods 2 for initial positioning of the flange to be processed. The sliding rods 301 are slidably mounted on the mounting slide rail 101 via the first T-shaped slider 3. The sliding rods 301 can be adjusted according to the size of the flange to be processed 7 to press against the outer wall of the flange to be processed 7. The lower edge of the flange to be processed 7 is lifted by the support rings 4 on the positioning rods 2 and the sliding rods 301, so that the flange to be processed 7 is in a suspended state, avoiding interference between the drill rod and the base 1 during drilling. The threaded rod 501 passes through the center of the flange to be processed 7, and the pressure plate 6 is slidably mounted on the threaded rod 501. The pressure plate 6 presses down on the flange to be processed 7 and fixes it on the base 1, thus achieving the purpose of clamping and fixing flanges 7 of different specifications and sizes.

[0022] In order to achieve the purpose of pressing down and fixing the flange 7 to be processed, the device adopts the following technical solution: a through hole 601 is opened in the pressure plate 6, the through hole 601 cooperates with the threaded rod 501, a fixing nut 502 is threaded on the threaded rod 501, a limit groove 602 is opened at both ends of the pressure plate 6, a limit slider 603 is slidably installed in the limit groove 602, and a pressure head 604 is fixedly connected to the other end of the limit slider 603, the pressure head 604 cooperates with the flange 7 to be processed.

[0023] The pressure plate 6 can be fitted onto the threaded rod 501 through the through hole 601. The second T-shaped slider 5 is slidably installed in the T-shaped slide groove 102. Tightening the fixing nut 502 can press down the pressure plate 6, allowing the threaded rod 501 to slide and adjust to the center position of the flange 7 to be processed. The limiting slider 603 is slidably installed inside the limiting slide groove 602, allowing the pressure head 604 to extend and pull for adjustment. The pressure head 604 can be adjusted according to the diameter of the center through hole of the flange 7 to be processed, pressing the pressure head 604 against the upper edge of the flange 7 to be processed, so that the pressure plate 6 can press down on flanges 7 of different specifications.

[0024] The working principle and usage process of this utility model are as follows: The outer wall of the flange 7 to be processed is placed against the two positioning rods 2. Then, by moving the first T-shaped slider 3, the sliding rod 301 is moved, so that the first T-shaped slider 3 also abuts against the outer wall of the flange 7 to be processed. The lower edge of the flange 7 to be processed is lifted by the support ring 4 on the positioning rod 2 and the sliding rod 301, so that the flange 7 to be processed is in a suspended state. The pressure plate 6 is sleeved and installed on the threaded rod 501, and the position of the pressure head 604 is manually adjusted so that the pressure head 604 rests on the edge of the inner hole of the flange 7 to be processed. At the same time, the pressure head 604 is tightened to move the pressure plate 6 down, and the pressure plate 6 will drive the pressure head 604 down to fix the flange 7 to be processed.
