Description

Technical Field

[0001] This utility model relates to a convenient fixing fixture for a pipeline heater. Background Technology

[0002] With the rapid development of the new energy vehicle industry, traditional automobile companies are increasingly investing in the new energy field, leading to intensified competition in the industry. This not only places higher demands on the quality of complete vehicles but also imposes strict constraints on the production capacity and consistency of auto parts.

[0003] In new energy vehicles, the optimal operating temperature for batteries is 25-35℃. To cope with extreme weather conditions such as heat and cold, reduce battery damage during use, and extend their service life, the battery thermal management system has become a core component. At the same time, due to the imbalance between power generation and consumption in different regions and the differences in electricity demand in different seasons and times, the application of energy storage heaters in battery energy storage systems is becoming increasingly widespread.

[0004] As a key component for battery thermal management systems and energy storage systems, the PTC new structure liquid heater has secured a certain market share due to its unique performance. The pipeline heater, as a crucial part of this liquid heater, directly impacts the overall equipment's capacity and reliability through its production efficiency and quality. In the production process of the pipeline heater, the fixing and gluing of the end brackets is one of the core steps. Currently, factories generally use a processing mode of "manually straightening the end brackets + gluing," which has the following significant drawbacks:

[0005] 1. Significant waste of manpower: It is necessary to arrange dedicated personnel to continuously and manually straighten the end brackets until the glue is poured and cured, which consumes a lot of manpower.

[0006] Second, low production efficiency: manual straightening operation can only fix one end bracket at a time, which cannot achieve batch processing and restricts the increase of production capacity;

[0007] 3. Low product qualification rate: Manual straightening makes it difficult to ensure the balance of the end bracket. During the glue pouring process, the bracket is prone to displacement, which can lead to product defects (such as uneven glue pouring, poor sealing, etc.), significantly reducing the qualification rate and increasing production costs.

[0008] To solve the above problems, there is an urgent need for a tooling that can replace manual operation and achieve stable fixation of the end bracket, so as to balance the requirements of efficiency, quality and cost. Utility Model Content

[0009] The purpose of this invention is to reduce the reliance on manual labor in the end bracket gluing process, thereby lowering labor costs, and to provide a convenient fixing fixture for pipe heaters. The specific technical solution is as follows:

[0010] A convenient fixing fixture for a pipe heater is used to fix the pipe heater end bracket during the glue-filling process. The pipe heater includes a central pipe structure and several PTC receiving grooves evenly distributed around the central pipe structure. PTC heating cores are installed in the PTC receiving grooves.

[0011] This type of convenient fixed fixture for pipeline heaters includes:

[0012] Includes an end bracket, the end bracket including an annular main structure, the annular main structure having a plurality of buckles evenly distributed in the circumferential direction, the head of the buckle extending toward the central axis of the annular main structure and abutting against the outer surface of the pipe heater;

[0013] The bottom of the annular main structure has a rectangular notch along the axial direction, and a clamping plate that can move up and down along the axial direction of the annular main structure is provided in the notch. The upper surface of the clamping plate can abut against the outer surface of the pipe heater.

[0014] The lower surface of the clamping plate is fixedly connected to the transmission slider, and the transmission slider is connected to the output end of the telescopic rod. The telescopic rod can drive the transmission slider to move the clamping plate up and down. A fixing block is fixedly connected to the outer surface of the annular main structure. A connecting groove is opened on the outer surface of the fixing block. The connecting groove can cooperate with fasteners to fix the annular main structure to the workbench surface.

[0015] Furthermore, the inner wall of the annular main structure is uniformly provided with a number of positioning blocks along the circumference. The number of positioning blocks is consistent with the number of PTC receiving slots and their positions correspond one-to-one. The positioning blocks are adapted to the slot openings of the PTC receiving slots.

[0016] The compatibility between the positioning block and the PTC receiving tank opening forms a "fitting positioning", which can not only quickly guide the operator to complete the initial placement of the pipeline heater, but also provide a benchmark for the initial clamping of the subsequent buckles and the stable clamping of the clamping plate, reducing the problem of glue displacement caused by positioning deviation and significantly improving the product qualification rate of the glue filling process.

[0017] Furthermore, the number of clips is 2-6, the clips are made of elastic material, and the heads of the clips have inwardly protruding structures. The clips can achieve initial fixation of the pipe, creating a stable foundation for the subsequent precise clamping of the clamping plates and reducing reliance on manual support.

[0018] Furthermore, the positioning block is a detachable structure, connected to the inner wall of the annular main structure by screws or clips. This detachable design also facilitates individual maintenance or replacement of the positioning block, extending the overall service life of the tooling.

[0019] Furthermore, the upper surface of the clamping plate is provided with anti-slip texture or a high-temperature resistant silicone pad. The elasticity of the silicone can fill in the slight unevenness on the outer surface of the pipe, making the clamping force of the clamping plate more uniform and avoiding excessive local pressure that could cause pipe deformation.

[0020] Furthermore, the fixing block is square in shape, the connecting groove is an oblong groove or a U-shaped groove, and a buffer pad is provided inside the connecting groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] By replacing manual alignment with automated clamping, no dedicated operators are required to continuously monitor the equipment. One operator can manage 3-4 dispensing machines that assemble this tooling at the same time, which can effectively reduce the labor and operating costs of the production line.

[0023] The positioning block that fits the inner wall of the annular main body and the PTC receiving tank can achieve precise initial positioning of the pipeline heater. Combined with the evenly distributed buckles in the circumference, it forms an initial clamping. Then, the telescopic rod drives the transmission slider to move the clamping plate up and down to achieve stable clamping of the pipeline heater. This not only ensures the stability and positioning accuracy during the clamping process, but also effectively avoids defects such as uneven glue filling and poor sealing caused by bracket displacement during glue filling, and significantly improves the product qualification rate.

[0024] This stable and precise fixing structure facilitates automatic alignment and automatic glue dispensing of the glue-dispensing components, overcoming the limitation of traditional manual operation which can only fix one bracket at a time. This effectively improves the production efficiency of the glue dispensing process. At the same time, the overall structural design is compatible with the central pipe and PTC receiving tank structure of the pipe heater, making it easy to operate and reliable to fix. It takes into account the needs of production efficiency, product quality and cost control, and provides a basic structure for the mass production of pipe heaters. Attached Figure Description

[0032] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0033] Example 1: As Figure 1-6 As shown, a convenient fixing fixture for a pipe heater includes an end bracket 4 for fixing a pipe heater 1. The pipe heater 1 includes a central pipe structure and a plurality of PTC receiving slots distributed circumferentially along the central pipe structure. A PTC heating core 2 is assembled in the PTC receiving slot.

[0034] The end support 4 includes an annular main structure that matches the end structure of the pipe heater 1. The annular main structure has several buckles 3 in the circumferential direction. The head of the buckle 3 extends towards the central axis of the annular main structure and can abut against the outer surface of the pipe heater 1. The interior of the annular main structure has several positioning blocks 41 that match the structure at the opening of the PTC receiving groove. The bottom of the annular main structure has a notch, and the notch has a clamping plate 42 that can move up and down along the axial direction of the annular main structure. The upper surface of the clamping plate 42 can abut against the outer surface of the pipe heater 1. The lower surface of the clamping plate 42 is fixedly connected to the transmission slider 43. At the same time, a fixing block is fixedly connected to the outer surface of the annular main structure. The outer surface of the fixing block has a connecting groove 44.

[0035] How to use:

[0036] S1. Fixture fixing: First, fix the annular main structure of the end bracket 4 on the workbench, align the connecting groove 44 with the mounting hole of the workbench, and screw the fastener through the connecting groove 44 into the mounting hole. After locking, ensure that the annular main structure is not loose, laying the foundation for subsequent operations.

[0037] S2. Preliminary positioning and clamping: Hold the pipe heater 1 to be filled with glue and insert its end into the annular main structure of the end bracket 4, so that the PTC receiving groove of the pipe heater 1 corresponds one-to-one with the positioning block 41 on the inner wall of the annular main body. The positioning block 41 is inserted into the groove to achieve circumferential positioning; at the same time, the buckle 3 undergoes elastic deformation due to the insertion of the pipe heater 1, and the head abuts against the outer surface of the pipe heater 1 to complete the preliminary fixation.

[0038] S3. Stable clamping: Start the telescopic rod (not shown in the figure), its output end pushes the transmission slider 43, which drives the clamping plate 42 to move upward within the rectangular notch at the bottom of the annular body. The upper surface of the clamping plate 42 gradually presses the outer surface of the pipe heater 1 until the pressing force reaches the standard and there is no loosening. Close the telescopic rod (not shown in the figure) to achieve stable clamping.

[0039] S4. Glue Dispensing and Part Removal: Direct glue dispensing is carried out. Due to precise positioning and stable clamping, the glue dispensing parts can be automatically aligned to ensure uniform glue dispensing. After the glue has cured, the telescopic rod is activated in the reverse direction. The transmission slider 43 drives the clamping plate 42 to move down and separate from the pipe heater 1, pulling the pipe heater 1 outward to separate it from the positioning block 41 and the buckle 3, thus completing the part removal.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
