Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically to a heat exchanger assembly substrate fixing and clamping device. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. During the manufacturing process, the components of the heat exchanger are assembled. The base plate of the heat exchanger is placed on the platform structure and clamped and positioned during assembly. This clamping device is used to clamp and position the base structure of the heat exchanger.

[0003] When clamping and positioning, ordinary clamping structures are simple, using threaded parts with a single structural direction to move from a fixed position and position the base in a fixed position. The single positioning method results in poor flexibility and adaptability during positioning. Summary of the Invention

[0004] The purpose of this invention is to provide a heat exchanger assembly base fixing clamping device to solve the problem mentioned in the background art that the existing clamping and positioning methods are simple, use threaded parts with a single structural direction, and move from a fixed position to fix the base in a fixed position. The positioning method is singular, resulting in poor flexibility and adaptability during positioning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat exchanger assembly base fixing clamping device, comprising a base in the shape of a square, a top seat connected to the top of the base, a notch in the shape of a concave character opened on the end wall of the top seat, a screw rod threaded to both end walls of the top seat, a fixed block fixedly connected to the end of the screw rod, an inclined wall formed on the side wall of the fixed block, and a screw push rod vertically threaded to the inclined wall.

[0006] Preferably, there are two screw rods, and the number of the fixed block and the screw push rod are twice the number of screw rods.

[0007] Preferably, a pair of slide rails are fixedly connected to the upper wall of the bottom of the base, and a slide block is movably connected to the end of the slide rails.

[0009] Preferably, the threaded opening is internally threaded and connected to a threaded rod, and two slides are provided.

[0010] Preferably, each end of the base has an opening for movement, and a movable plate is movably connected to the opening.

[0011] Preferably, the movable plate has vertically spaced screw holes at equal intervals in the center, and the movable plate has placement openings symmetrically arranged about the screw holes. A positioning rod that is threadedly connected to the screw holes is movably connected to the placement opening, and a screw is threadedly connected to the top side wall of the base.

[0013] Preferably, the base has a through-hole at the top center, a connecting rod is threaded to the side wall of the through-hole, and a support seat is fixed to the side wall of the connecting rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the recess of the top seat to place the heat exchanger base. The screw rotates and the end of the screw is used to position and clamp the base. At the fixed block on the end wall of the screw, a screw push rod is threadedly connected to the inclined wall. The screw push rod is arranged at an inclination. The screw push rod rotates and the screw push rod moves. It squeezes and limits the unevenness or inclined end wall of the base from the inclination angle. It is used to adapt and position bases of different shapes, making positioning more flexible and convenient. 2. The movable plate at the movable opening is movable and used to move the movable plate and top seat, changing the height position of the top seat. The height of the top seat is controllable and adjustable, making it more convenient and flexible to use. Tighten the screw and insert it into the screw hole to lock and limit the top seat after the position is adjusted. 3. At the same time, after the movable plate moves up, the end wall of the movable plate is exposed, and the screw holes are also exposed. At this time, the positioning rod in the placement port can be moved up and taken out, and then the positioning rod can be inserted into the exposed screw holes. Multiple positioning rods can be screwed at the same time, and the ends form a clamping shape to clamp and position the base placed on the upper wall of the base. The base support method is more diverse. The top seat can be used to place the base material. When the top seat moves up, the upper wall of the base is exposed, which can also be used to place the base material. 4. The slide rail and slide groove are movable, which is used for moving the slide block. It is convenient to change the position of the slide block. The position of the slide block is controllable and adjustable, making it more flexible to use. The threaded hole at the end wall of the slide block is connected to the threaded rod, which facilitates the adjustment of the displacement of the threaded rod. When the threaded rod is displaced, the end wall of the threaded rod is exposed, which can be used to support the heat exchanger accessories to be assembled. 5. The through-hole can be used to penetrate the top cylinder. The connecting rod rotates to move the support seat laterally. The position of the support seat is controllable and adjustable. The end wall of the support seat can be used to assist in supporting the reference material of the heat exchanger. The upper wall of the top cylinder is used to support the material. After the top cylinder rotates, the displacement height of the top cylinder is controllable and adjustable to change the height of the supported material. Attached Figure Description
