Description

Technical Field

[0001] This utility model relates to the field of air conditioning distribution pipe punching technology, and more specifically, it relates to a positioning tooling for air conditioning distribution pipe punching. Background Technology

[0002] Air conditioning distribution pipes are the core piping components in central air conditioning systems responsible for the transportation and distribution of cold and heat media. They serve as a bridge connecting the air conditioning unit and terminal equipment. Their main function is to accurately deliver the cooling or heating capacity processed by the unit to various spaces within the building that require temperature control. At the same time, through reasonable pipe design, pipe diameter matching, and valve regulation, they ensure that each terminal device receives a uniform and stable media flow, thereby achieving precise regulation of indoor temperature.

[0003] Currently, in order to install and use the air conditioning distribution pipe, the air conditioning distribution pipe needs to be punched during the manufacturing process. However, during the punching process, the end of the pipe is not supported. If the hole is punched directly near the end of the pipe, the end of the pipe will deform, affecting the subsequent use of the pipe. A positioning tool for punching the air conditioning distribution pipe is proposed to improve the existing problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning tool for punching holes in air conditioning distribution pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A positioning fixture for punching air conditioning distribution pipes includes a worktable, a punching assembly on the top of the worktable, a workpiece below the punching assembly, and a set of auxiliary components at each end of the workpiece.

[0006] The auxiliary component includes an electric slide rail, a mounting bracket is slidably connected above the electric slide rail, an auxiliary mechanism is provided on the mounting bracket, a plurality of support seats are provided on one side of the electric slide rail, a groove is provided on the top of the support seat, and the workpiece is placed inside the groove.

[0007] The punching assembly includes a punching cylinder, a connecting plate is provided on one side of the punching cylinder, and a plurality of punching heads are provided on the bottom of the connecting plate.

[0008] By adopting the above technical solution, punching can be performed on the workpiece by setting a punching assembly. Two sets of auxiliary components are respectively set at both ends of the workpiece, and the two sets of auxiliary components can provide auxiliary support for the workpiece, reducing the possibility of end deformation of the workpiece during the punching process.

[0009] The present invention is further configured such that: the auxiliary mechanism includes a telescopic cylinder, the output end of the telescopic cylinder is connected to an output shaft, and a filling seat is provided at the end of the output shaft away from the telescopic cylinder.

[0010] The present invention is further configured such that: three sets of connecting rods are provided on the outer side of the telescopic cylinder, and the three sets of connecting rods are respectively hinged to the telescopic cylinder.

[0011] The present invention is further configured such that: each of the three sets of connecting rods is provided with a set of grippers at the end away from the telescopic cylinder, the grippers are hinged to the connecting rods, and the grippers are configured with an L-shaped structure.

[0012] The present invention is further configured such that: a connecting block is provided on the outer side of the output shaft, the connecting block is fixedly connected to the output shaft, and the three sets of grippers are respectively hinged to the connecting block.

[0013] By adopting the above technical solution, the telescopic cylinder can provide power for the movement of the auxiliary mechanism. The extension and contraction of the telescopic cylinder can control the extension and contraction of the output shaft. Since the output shaft is fixedly connected to the filling seat, the filling seat can achieve extension and contraction movement under the drive of the output shaft. The filling seat is made of rubber and is cylindrical in shape with a conical end. The conical end facilitates the insertion of the filling seat into the workpiece, thereby facilitating the filling seat to provide auxiliary support for the workpiece inside and reducing the possibility of deformation of the workpiece end during punching.

[0014] The present invention is further configured such that: the punching assembly further includes a mounting bracket, the punching cylinder is disposed on the top of the mounting bracket, and the output end of the punching cylinder passes through the mounting bracket and is connected to the connecting plate.

[0015] The present invention is further configured such that: two sets of sliding rods are symmetrically arranged at the bottom of the mounting bracket, and a set of sliding cylinders are slidably connected to the outer side of each of the two sets of sliding rods, and the two sets of sliding cylinders are respectively connected to the connecting plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects: The electric slide rail facilitates the adjustment of the position of the auxiliary mechanism, enabling the auxiliary mechanism to clamp and limit the workpiece. By using the auxiliary mechanism to limit the workpiece, the possibility of workpiece deformation during the punching process is reduced. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] Please see Figures 1-4 The present invention provides the following technical solution: Example 1, see Figure 1 A positioning fixture for punching air conditioning distribution pipes includes a worktable 1, a punching assembly 3 on the top of the worktable 1, a workpiece 4 below the punching assembly 3, and a set of auxiliary components 2 at each end of the workpiece 4.

[0025] The punching assembly 3 can be used to punch the workpiece 4. Two sets of auxiliary assemblies 2 are respectively set at both ends of the workpiece 4. The two sets of auxiliary assemblies 2 can provide auxiliary support for the workpiece 4 and reduce the possibility of end deformation of the workpiece 4 during the punching process.

[0026] The specific structure of auxiliary component 2 is as follows: See Figure 2 and Figure 3 The auxiliary component 2 includes an electric slide rail 21, a mounting bracket 22 is slidably connected above the electric slide rail 21, an auxiliary mechanism 23 is provided on the mounting bracket 22, a number of support seats 24 are provided on one side of the electric slide rail 21, a groove is provided on the top of the support seat 24, and the workpiece 4 is placed inside the groove.

[0027] Among them, several support seats 24 are staggered on both sides of the punching position of the workpiece 4. The groove on the top of the support seat 24 is adapted to the shape of the workpiece 4. By setting multiple sets of support seats 24, the workpiece 4 can be supported.

[0028] The working principle of electric slide rail 21 is to use a motor to provide power, and the rotational motion of the motor is converted into linear motion through a ball screw, which drives the slider on the slide rail to move along the track.

[0029] The auxiliary mechanism 23 is installed on the mounting frame 22. When the electric slide rail 21 is activated, the electric slide rail 21 can drive the mounting frame 22 and the auxiliary mechanism 23 to move horizontally. The electric slide rail 21 facilitates the adjustment of the position of the auxiliary mechanism 23, which facilitates the auxiliary mechanism 23 to clamp and limit the workpiece 4. By using the auxiliary mechanism 23 to limit the workpiece 4, the possibility of deformation of the workpiece 4 during the punching process is reduced.

[0030] The specific structure of auxiliary mechanism 23 is as follows: See Figure 3 and Figure 4 The auxiliary mechanism 23 includes a telescopic cylinder 231, the output end of which is connected to an output shaft 236, and a filling seat 235 is provided at the end of the output shaft 236 away from the telescopic cylinder 231.

[0031] See Figure 3 and Figure 4 Three sets of connecting rods 232 are provided on the outside of the telescopic cylinder 231, and the three sets of connecting rods 232 are respectively hinged to the telescopic cylinder 231.

[0032] See Figure 3 and Figure 4 Each of the three sets of connecting rods 232 is provided with a set of grippers 233 at the end away from the telescopic cylinder 231. The grippers 233 are hinged to the connecting rods 232 and are configured as L-shaped structures.

[0033] See Figure 3 and Figure 4 A connecting block 234 is provided on the outer side of the output shaft 236. The connecting block 234 is fixedly connected to the output shaft 236, and three sets of grippers 233 are respectively hinged to the connecting block 234.

[0034] The telescopic cylinder 231 provides power for the movement of the auxiliary mechanism 23. The extension and retraction of the telescopic cylinder 231 can control the extension and retraction of the output shaft 236. Since the output shaft 236 is fixedly connected to the filling seat 235, the filling seat 235 can move by extension and retraction under the drive of the output shaft 236. The filling seat 235 is made of rubber and is cylindrical in shape with a conical end. The conical end makes it easy for the filling seat 235 to be inserted into the workpiece 4, thereby facilitating the filling seat 235 to provide auxiliary support for the workpiece 4 inside and reducing the possibility of deformation of the end of the workpiece 4 during the punching process.

[0035] The telescopic cylinder 231 provides power for the movement of the entire auxiliary mechanism 23. It is fixedly connected to the output shaft 236 and the connecting block 234. Since the connecting block 234 is hinged to the three sets of grippers 233, the three sets of grippers 233 are hinged to the three sets of connecting rods 232, and the three sets of connecting rods 232 are respectively hinged to the telescopic cylinder 231, when the telescopic cylinder 231 is in the extended state, the three sets of grippers 233 are in the far-away state, that is, the three sets of grippers 233 release the workpiece 4. When the telescopic cylinder 231 is in the retracted state, the three sets of grippers 233 are in the close-to-close state, that is, the three sets of grippers 233 can clamp the workpiece 4.

[0036] With the above settings, when the three sets of grippers 233 move away from each other, the filling seat 235 is in an extended state. At this time, the filling seat 235 can be inserted into the interior of the workpiece 4 to provide auxiliary support for the workpiece 4. When the three sets of grippers 233 are controlled to move closer to each other, the three sets of grippers 233 can clamp the workpiece 4.

[0037] During the clamping process, the movement of the three sets of jaws 233 remains synchronized, so that the workpiece 4 is subjected to uniform force, reducing the damage to the workpiece surface or displacement caused by excessive local pressure. At the same time, the tapered end design of the filler seat 235 can effectively guide it into the interior of the workpiece 4, reducing friction and jamming, thereby improving the smoothness of operation. In addition, the rubber filler seat 235 not only has good elasticity, but also provides a buffering effect when in contact with the workpiece 4, further protecting the workpiece surface from scratches or pressure damage.

[0038] In practical applications, firstly, the robot arm picks up the workpiece 4 and places it on the support seat 24. At this time, the robot arm has not left the workpiece 4. Then, the two sets of electric slide rails 21 are activated. The two sets of electric slide rails 21 drive the two sets of auxiliary mechanisms 23 to approach the two ends of the workpiece 4. When the auxiliary mechanisms 23 approach the two ends of the workpiece 4, the two sets of telescopic cylinders 231 are activated to extend. Driven by the two sets of telescopic cylinders 231, the two sets of filling seats 235 are inserted into the two ends of the workpiece 4 respectively. After the positions of the two sets of filling seats 235 are determined, the two sets of telescopic cylinders 231 are activated again to retract. Driven by the two sets of telescopic cylinders 231, the grippers 233 clamp the workpiece 4. After the two sets of auxiliary mechanisms 23 provide auxiliary support to the two ends of the workpiece 4 respectively, the robot arm releases the workpiece 4.

[0039] The specific structure of punching assembly 3 is as follows: See Figure 2 The punching assembly 3 includes a punching cylinder 33, a connecting plate 35 is provided on one side of the punching cylinder 33, and a plurality of punching heads 36 are provided at the bottom of the connecting plate 35.

[0040] See Figure 2 The punching assembly 3 also includes a mounting bracket 31, and a punching cylinder 33 is disposed on the top of the mounting bracket 31. The output end of the punching cylinder 33 passes through the mounting bracket 31 and is connected to the connecting plate 35.

[0041] See Figure 2 Two sets of sliding rods 32 are symmetrically arranged at the bottom of the mounting bracket 31. A set of sliding cylinders 34 is slidably connected to the outer side of each set of sliding rods 32. The two sets of sliding cylinders 34 are respectively connected to the connecting plate 35.

[0042] Among them, several punching heads 36 correspond to the punching points of workpiece 4 respectively. Driven by punching cylinder 33, several punching heads 36 can punch workpiece 4.

[0043] In practical applications, when the punching cylinder 33 is activated to extend, the two sets of sliding cylinders 34 slide downward along the two sets of sliding rods 32 under the drive of the punching cylinder 33. The connecting plate 35 moves downward with the two sets of sliding cylinders 34, and several punching heads 36 move downward with the connecting plate 35. During the movement, the punching heads 36 can perform punching processing on the workpiece 4. After the punching is completed, the punching cylinder 33 is activated again to retract, and the several punching heads 36 move away from the workpiece 4 under the drive of the punching cylinder 33.

[0044] During the punching process, the cooperative design of the slide bar 32 and the sliding cylinder 34 effectively reduces the shaking during the movement, thereby improving the overall processing accuracy. When the punching cylinder 33 retracts, the entire punching assembly 3 returns to its initial state, ready for the next processing.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
