Description

Technical Field

[0001] This utility model belongs to the field of valve metal parts processing technology, specifically relating to a positioning device for valve metal parts processing. Background Technology

[0002] Valve metal parts refer to the components made of metal materials in valves. During the processing of valve metal parts, positioning devices are usually used to position the valve shell to ensure that the metal parts can be accurately positioned and fixed during processing, so as to guarantee processing quality and improve production efficiency.

[0003] For example, patent CN222289428U discloses a positioning device for processing valve metal parts. Technical problem: Existing valve positioning devices are generally inconvenient for quickly loading and unloading valves, and for quickly moving the valves to the processing area for positioning, resulting in poor valve positioning performance. Technical solution: A positioning device for processing valve metal parts includes a moving component; it also includes a valve body component, a guide component, a loading component, a first positioning component, and a second positioning component.

[0004] In the process of using the aforementioned positioning device for processing valve metal parts, the valve body needs to be unloaded by personnel pulling the mounting plate below it one by one. Without the mounting plate limiting the movement, the valve body will fall vertically into the middle of the moving plate along the guide body, thus achieving the effect of portable unloading. However, without personnel assistance, both the valve body and the moving plate may be damaged when they come into contact with each other during the vertical fall. Furthermore, the valve body needs to be manually pulled out multiple times to achieve the purpose of unloading, which is quite troublesome and not portable. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a positioning device for processing metal valve parts. This device aims to solve the problem that in existing technologies, unloading valve bodies requires personnel to sequentially pull the mounting plate below them. Without the mounting plate limiting the movement, the valve body will fall vertically into the middle of the moving plate along the guide body, thus achieving a portable unloading effect. However, without personnel assistance, both the valve body and the moving plate may be damaged when they come into contact with each other during the vertical drop. Furthermore, manually pulling the valve body multiple times to achieve the purpose of unloading the valve body is also quite cumbersome and not portable enough.

A transmission screw is installed in the middle of one of the guide grooves, and a first motor is installed at one end of the transmission screw. A screw sleeve is screwed around one side of the transmission screw.

[0010] Furthermore, there are two guide slots, and one of the guide slots is connected to the operating table via a movable guide connection.

[0011] Furthermore, the feeding assembly includes two first rotating rods, which are symmetrically mounted on the rear sides of the assembly frame. A gear is fixed around one end of each of the two first rotating rods, and a first synchronous pulley is fixed around the other end of each of the two first rotating rods. A second motor is mounted on one end of one of the first rotating rods.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention allows operators to pre-place multiple valve metal parts to be processed on rubber blocks on opposite sides of two belts inside the assembly frame. When processing is required, the operator starts a second motor to rotate one of the first rotating rods and gears. This causes the other gear, meshing with the first rotating rod, to rotate in the opposite direction. Guided by a first synchronous pulley on each first rotating rod, the first rotating rod rotates along with a synchronous belt and another second synchronous pulley. Since a drive belt roller is installed in the middle of the two second synchronous pulleys, the drive belt roller, in conjunction with the driven belt roller, rotates the rubber blocks around the belt. At this moment, the valve metal parts placed on the inner rubber blocks of the two belts descend at a uniform speed until the lowest valve metal part is stably placed above the operating table. Then, the operator starts the first motor to rotate the transmission screw. The screw sleeve interacting with the screw moves the operating table and the valve metal parts to the processing area on one side of the base. This process is repeated, and the operator can replenish the empty parts by adding materials.

[0018] When the valve metal part is positioned above the operating table, the operator can activate two electric push rods. The extended ends of the two push rods, along with positioning guide blocks, guide the valve metal part to clamp and position both ends along the guide groove. At this time, the operator can then perform processing operations on the valve metal part. Attached Figure Description

[0025] 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.

[0026] This specific embodiment is a positioning device for machining valve metal parts, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the system includes a base 1, an assembly frame 2 fixedly mounted on one side of the upper part of the base 1, and a preset groove 3 opened in the middle of the upper part of the base 1. A stable feeding mechanism 4 is jointly installed in the middle of the preset groove 3 and the assembly frame 2. The stable feeding mechanism 4 includes a displacement component 41 and a lead screw sleeve 414 therein. An operating table 5 is fixedly mounted on the inner side of the lead screw sleeve 414. Positioning mechanisms 6 are installed on both sides of the upper part of the operating table 5. The displacement component 41 is installed on both sides inside the preset groove 3. The displacement component 41 includes a guide groove 411, which is located on both sides of the middle of the preset groove 3. A transmission lead screw 412 is installed in the middle of one of the guide grooves 411, and a first motor 413 is installed at one end of the transmission lead screw 412. A screw thread is installed around one side of the transmission lead screw 412. The assembly frame 2 is equipped with a lead screw sleeve 414 and two guide grooves 411, one of which is connected to the operating table 5 via a movable guide connection. A feeding assembly 42 is installed in the middle of the assembly frame 2. The feeding assembly 42 includes two first rotating rods 421, which are symmetrically installed on the rear sides of the assembly frame 2. A gear 422 is fixed around one end of each of the two first rotating rods 421, and a first synchronous pulley 424 is fixed around the other end. A second motor 423 is installed at one end of one of the first rotating rods 421. A synchronous belt 425 is provided around the two first synchronous pulleys 424, and a second synchronous pulley 426 is provided inside one end of each synchronous belt 425. Each of the synchronous pulleys 426 has a drive belt roller 427 installed in its middle, and each of the two drive belt rollers 427 has a belt 428 installed around its periphery. A driven belt roller 4211 is installed on the inner side of the other end of each of the two belts 428, and rubber side blocks 429 are provided on the outer periphery of each of the two belts 428. A limit block 4210 is fixed on one side above the rubber side block 429. Two first rotating rods 421 are provided, and the gears 422 installed around the two first rotating rods 421 are aligned and meshed. Workers can pre-place multiple valve metal parts to be processed on the rubber side blocks 429 on the opposite sides of the two belts 428 inside the assembly frame 2. When processing is required, the second motor 423 can be started. When one of the first rotating rods 421 and gears 422 rotates, the other gear 422 meshing with it can rotate in the opposite direction, causing the corresponding fixed first rotating rod 421 to rotate. At this time, guided by a first synchronous pulley 424 on each of the first rotating rods 421, the synchronous belt 425 and another second synchronous pulley 426 can rotate. Since a drive belt roller 427 is installed in the middle of the two second synchronous pulleys 426, the drive belt roller 427 can cooperate with the driven belt roller 4211 to drive the belt 428 and the rubber side blocks 429 around it to rotate. At this time, the valve metal parts that are placed on the rubber side blocks 429 on the inner side of the two belts 428 can descend at a constant speed until the lowest valve metal part can be stably placed above the operating table 5.Next, the operator starts the first motor 413, causing the transmission screw 412 to rotate. At this moment, the screw sleeve 414, which interacts with the screw, can move the operating table 5 and the valve metal parts to one side of the processing area on the base 1. This process is repeated, and subsequent operators can replenish materials in the empty areas.

[0027] The positioning mechanism 6 includes fixed blocks 61, which are located on both sides above the operating table 5. Electric push rods 62 are installed in the middle of the two fixed blocks 61, and the extended ends of the two electric push rods 62 are connected to positioning guide clamps 63. Guide grooves 64 are provided on both sides above the operating table 5. The guide grooves 64 and the positioning guide clamps 63 are connected by a movable guide. When the valve metal part is above the operating table 5, the operator can activate the two electric push rods 62. The extended ends of the two push rods can guide the positioning guide clamps 63 along the guide grooves 64 to clamp and position the two ends of the valve metal part. At this time, the operator can perform processing operations on the valve metal part.

[0028] Working principle: Workers can pre-place multiple valve metal parts to be processed on the rubber blocks 429 on opposite sides of two belts 428 inside the assembly frame 2. When processing is required, the worker can start the second motor 423 to rotate one of the first rotating rods 421 and gears 422. This causes the other gear 422, which meshes with it, to rotate the corresponding fixed first rotating rod 421 in the opposite direction. Guided by a first synchronous pulley 424 on each first rotating rod 421, it rotates the synchronous belt 425 and another second synchronous pulley 426. Since a drive belt roller 427 is installed in the middle of the two second synchronous pulleys 426, the drive belt roller 427, in conjunction with the driven belt roller 4211, drives the belt 428, which is surrounded by rubber blocks 429. When the rubber edge block 429 rotates, the valve metal parts, which are mounted on the rubber edge blocks 429 inside the two belts 428, can descend at a constant speed until the lowest valve metal part can be stably placed above the operating table 5. Then, the operator starts the first motor 413 to rotate the transmission screw 412. At this time, the screw sleeve 414, which interacts with the screw, can move the operating table 5 and the valve metal parts to the processing area on one side of the base 1. This process is repeated, and the operator can replenish the empty parts. After the valve metal parts are above the operating table 5, the operator can start the two electric push rods 62. The extended ends of the two push rods can carry the positioning guide blocks 63 along the guide groove 64 to clamp and position the two ends of the valve metal parts. At this time, the operator can start processing the valve metal parts.

[0029] All technical features in this embodiment can be freely combined according to actual needs.
