A manifold B is respectively installed, spliced and fixed in the grooves at the left and right ends of the heat dissipation core body A. A pipe one C is connected through the back end of the manifold B on the left side, and a pipe two D is connected through the front end of the manifold B on the right side. The right end of the pipe one C and the pipe two D are connected together by a bracket E located therebetween. The assembly and processing process of the parallel-flow oil cooler includes multiple processing procedures. Among them, the clamping and splicing procedure between the heat dissipation core body and the manifold has always relied on the simple cooperation of a press and a worker's hammer. This assembly method is greatly affected by human operation factors, it is difficult to ensure the assembly accuracy between the heat dissipation core body and the manifold, and the labor intensity is high and the assembly efficiency is low, which seriously restricts the production and processing efficiency of the parallel-flow oil cooler. Therefore, the utility model provides an assembling device for a parallel-flow oil cooler in order to solve the above technical problems. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide an assembling device for a parallel-flow oil cooler.

The second clamping assembly is used to push the right manifold to the left and splice it into the groove at the right end of the heat dissipation core body, and the third clamping assembly is used to push the left manifold to the right and splice it into the groove at the left end of the heat dissipation core body. Compared with the traditional clamping and splicing method between the heat dissipation core body and the manifold, it effectively reduces the positioning difficulty during the assembly of each component, the operation is simple, and at the same time, the manual operation difficulty and labor amount are greatly reduced, thereby significantly improving the assembly efficiency between the heat dissipation core body and the manifold, overcoming the influence of human factors on the positioning of each component, and effectively improving the assembly accuracy between the heat dissipation core body and the manifold; the overall structure is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0004] To achieve the above purpose, the technical solution of the utility model is to design an assembling device for a parallel-flow oil cooler, which includes a bottom plate. A first clamping assembly for placing and clamping the heat dissipation core body on the parallel-flow oil cooler is arranged in the middle of the upper end surface of the bottom plate. A second clamping assembly for pushing the right manifold to the left and splicing it into the groove at the right end of the heat dissipation core body is arranged at the right end of the upper end surface of the bottom plate. A third clamping assembly for pushing the left manifold to the right and splicing it into the groove at the left end of the heat dissipation core body is arranged at the left end of the upper end surface of the bottom plate.

When in use, one side strip is clamped on the front edge of the heat dissipation core body, and the other side strip is clamped on the rear edge of the heat dissipation core body.

[0005] An assembly device for a parallel flow oil cooler of the present utility model, when in use, the fins, flat tubes and side plates that make up the heat dissipation core are assembled and clamped on the first clamping assembly to form the heat dissipation core. The right collector pipe is pushed leftward by the second clamping assembly and spliced into the groove at the right end of the heat dissipation core. The left collector pipe is pushed rightward by the third clamping assembly and spliced into the groove at the left end of the heat dissipation core. Compared with the traditional clamping and splicing method between the heat dissipation core and the collector pipe, it effectively reduces the positioning difficulty during the assembly of each component, has a simple operation, and at the same time greatly reduces the manual operation difficulty and labor volume, thereby significantly improving the assembly efficiency between the heat dissipation core and the collector pipe, overcoming the influence of human factors on the positioning of each component, and effectively improving the assembly accuracy between the heat dissipation core and the collector pipe; the overall structure is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0006] The preferred technical solution is that the first clamping assembly includes a fixed plate, a first movable plate, two first pillow beams and two second pillow beams. The two first pillow beams are fixedly arranged in parallel at intervals on the front side of the middle part of the upper end surface of the bottom plate. The fixed plate is fixedly arranged on the upper end surfaces of the two first pillow beams. A first stop block along the left-right direction is fixedly arranged at the front end edge of the upper end surface of the fixed plate. The two second pillow beams are fixedly arranged in parallel at intervals on the rear side of the middle part of the upper end surface of the bottom plate. A first slide rail along the front-rear direction is fixedly arranged on the upper end surface of the second pillow beam. Slide sleeves that are slidably matched with the corresponding first slide rails are respectively arranged on the left and right sides of the lower end surface of the first movable plate. An internal thread sleeve is fixedly arranged in the middle of the lower end surface of the first movable plate. It also includes a first lead screw that is screwed and matched with the internal thread sleeve. The first lead screw passes through the lower part of the fixed plate along the front-rear direction. The front and rear ends of the first lead screw are respectively rotatably installed on a support seat fixedly arranged on the upper end surface of the bottom plate. A handwheel for rotating the first lead screw to drive the first movable plate to horizontally move back and forth along the front end surface of the fixed plate is arranged at the front end of the first lead screw. The handwheel is located outside the front end surface of the fixed plate, and several handles are arranged on the outer peripheral side of the handwheel. The structure of the first clamping assembly is simply designed. When in use, only a plurality of fins and flat tubes need to be alternately placed in parallel on the fixed plate, and the fins, flat tubes and the two ends of the front and rear side plates are positioned by cooperating with the third clamping assembly on the left and the second clamping assembly on the right. By holding the handle and rotating the handwheel on the first clamping assembly, the first movable plate can be driven to move forward to clamp a plurality of fins, flat tubes and the front and rear side plates, or move backward to release a plurality of fins, flat tubes and the front and rear side plates. The operation is simple.

[0007] Further preferred technical solutions also include that on the front and rear sides of the left and right end faces of the fixed plate, second stoppers for limiting the corresponding side bars are fixedly provided respectively; on the upper end face of the fixed plate, positioning blocks corresponding to the left front end of the left pillow beam 1 and the right front end of the right pillow beam 1 are fixedly provided. On the left and right side edges of the lower end face of the first movable plate, a third stopper is fixedly provided respectively, and a limiting screw rod cooperating with the corresponding side positioning block is screwed and installed on the third stopper. The second stopper plays a role in limiting the corresponding side bar placed on the fixed plate, ensuring that the side bar can be completely and correspondingly attached to the corresponding side edge of the heat dissipation core; when the components of the heat dissipation core are clamped by driving the first movable plate to move forward by holding the handle and rotating the handwheel on the first clamping assembly, when the limiting screw rod abuts against the corresponding side positioning block, stop rotating the handwheel. This is convenient for accurately judging whether the first movable plate has moved in place, has low requirements for operators, is simple to operate, and helps to eliminate the influence of human factors.

[0008] Further preferred technical solutions also include that there are two first stoppers, and a first notch groove located in the middle of the fixed plate is formed between the two first stoppers. The middle of the front end of the first movable plate has a second notch groove corresponding to the first notch groove.

[0009] Preferred technical solutions also include that the second clamping assembly includes a second movable plate, two pillow beams 3, and a lifting and horizontal plate.

The lower end of the piston rod of the first cylinder movably penetrates through the through hole in the middle of the lifting and horizontal plate and is fixedly provided at the left end of the second movable plate. An arc-shaped groove for placing and clamping the manifold is formed by enclosing the left end of the second movable plate and the left end of the lifting and horizontal plate. An internal thread sleeve is fixedly provided on the lower end face of the second movable plate. It also includes a second lead screw screwed and cooperating with the internal thread sleeve. The two ends of the second lead screw are respectively rotatably installed on a support seat fixedly provided on the upper end face of the bottom plate. A handwheel for rotating the second lead screw to drive the second movable plate to horizontally move along the left-right direction is provided at the right end of the second lead screw. The handwheel is located outside the right end face of the second movable plate, and a plurality of handles are provided on the outer peripheral side of the handwheel;

[0010] The third clamping component has the same structure as the second clamping component, and the two are arranged symmetrically with respect to the first clamping component as mirror images on the bottom plate. The structure of the second clamping component or the third clamping component is simple. During use, the manifold is first placed and clamped inside the arc-shaped groove on the second clamping component or the third clamping component. By rotating the handwheel, the manifold is driven to move towards the end of the assembled and clamped heat dissipation core, and finally is embedded and spliced inside the corresponding groove at the end of the heat dissipation core. The operation steps are simple.

[0011] A further preferred technical solution is that there are also two core end limiting components for limiting the two ends of the heat dissipation core on the parallel flow oil cooler. One of the core end limiting components is located between the second clamping component and the first clamping component, and the other core end limiting component is located between the third clamping component and the first clamping component. When using the first clamping component to splice a number of fins and flat tubes alternately to form a heat dissipation core, the core end limiting components on the left and right sides of the first clamping component play a role in limiting the two ends of the flat tube, thereby facilitating the positioning of the flat tube and the fins, and helping to improve the splicing and positioning efficiency and accuracy of the heat dissipation core.

[0012] A further preferred technical solution is that the core end limiting component includes two L-shaped support plates fixed on the upper end surface of the bottom plate, a lifting vertical plate, a second cylinder, and a core limiting block. The two L-shaped support plates are correspondingly located on the front and rear sides of the left end of the second clamping component or the front and rear sides of the right end of the third clamping component. A third slide rail in the longitudinal direction is fixed on the two L-shaped support plates. Sliding sleeves that are slidably matched with the corresponding third slide rails are respectively provided at the front and rear ends of the lifting vertical plate. The second cylinder is fixed on the lower side of the bottom plate. The upper end of the piston rod of the second cylinder movably penetrates the through hole on the bottom plate and is fixedly connected to the middle of the lifting vertical plate. The cross-section of the core limiting block is a "7"-shaped structure. The vertical plate of the core limiting block faces the left or right side of the first clamping component in parallel, and a number of gap grooves for inserting and limiting the flat tube on the heat dissipation core are arranged at intervals in the front and rear directions on the vertical plate of the core limiting block. A number of fixing blocks extending downward are fixedly arranged at intervals on the vertical surface of the horizontal plate of the core limiting block away from the first clamping component. The fixing blocks and the core limiting block enclose a downward-opening clamping groove, and a handle is provided at the top of the horizontal plate of the core limiting block. The structure of the core end limiting component is simple. When using the first clamping component to splice a number of fins and flat tubes alternately to form a heat dissipation core, the end of the flat tube can be inserted into the gap groove on the corresponding core limiting block. The operation is simple. After the first clamping component clamps and splices the heat dissipation core, the core limiting block is removed, and then the lifting vertical plate is lowered to perform the subsequent docking and splicing operation between the manifold and the heat dissipation core.

[0013] A further preferred technical solution is that a positioning vertical plate for positioning the corresponding side manifold is vertically fixed on one side of the lifting vertical plate facing the movable plate two, and a positioning step adapted to the middle gap on the clamping side manifold placed on the second clamping assembly or the third clamping assembly is provided on the side of the positioning vertical plate away from the lifting vertical plate;

[0014] A limiting plate one for limiting the corresponding side manifold is fixed on the front end face or the rear end face of the movable plate two, and a limiting plate two for limiting the lifting vertical plate is fixed on the top of the L-shaped support plate. The positioning step on the positioning vertical plate is correspondingly adapted to the middle gap on the corresponding side manifold, so as to accurately position the corresponding side manifold by using the positioning step, ensure the accurate positioning between the manifold and the end groove of the heat dissipation core, ensure the smoothness when the manifold is embedded and spliced into the end groove of the heat dissipation core, and ensure the product accuracy at the same time.

[0015] A further preferred technical solution is that it includes a box body. On the upper end face of the top plate of the box body, a plurality of support frames are fixedly arranged at corresponding parallel intervals in the left-right direction. The upper end faces of the plurality of support frames are fixedly provided with the bottom plate, and the bottom plate is of an inclined structure with the front end lower and the rear end higher. The included angle between the bottom plate and the horizontal plane is 25-45°. The bottom plate is designed as an inclined structure with the front end lower and the rear end higher, and the included angle between the bottom plate and the horizontal plane is 25-45°, which conforms to the ergonomic principle, ensures the comfort of the splicing operation between the heat dissipation core and the manifold, helps to reduce the manual operation difficulty and improve the assembly efficiency.

[0018] 1. For the assembly equipment for a parallel flow oil cooler of the present utility model, when in use, the fins, flat tubes and side plates forming the heat dissipation core are assembled and clamped on the first clamping assembly to form the heat dissipation core. The second clamping assembly is used to push the right manifold to the left and splice it into the groove at the right end of the heat dissipation core, and the third clamping assembly is used to push the left manifold to the right and splice it into the groove at the left end of the heat dissipation core.

The operation is simple.

[0020] 3. When using the first clamping assembly to alternately arrange and splice a number of fins and flat tubes into a heat dissipation core body, the core body end limiting assemblies on the left and right sides of the first clamping assembly play a limiting role on the two ends of the flat tubes, thus facilitating the positioning of the flat tubes and fins, and helping to improve the splicing and positioning efficiency and accuracy of the heat dissipation core body.

[0052] The working principle of an assembly device for a parallel flow oil cooler of the present utility model:

[0053] Step 1: Rotate the handwheel F on the clamping assembly 1 to adjust the distance between the front end face of the movable plate 2-2 and the rear end face of the stop block 2-2a to the maximum. Then, start the cylinder 3-8 on the clamping assembly 3 and the cylinder 3-8 on the clamping assembly 4 through the control system, so that the piston rod of the cylinder 3-8 extends and raises the lifting vertical plate 3-7 to a certain height. Clamp two core limit blocks 3-9 on the lifting vertical plates 3-7 of the two core end limit assemblies 5 through the card slots 3-9c respectively, and make the gap grooves 3-9a of the core limit blocks 3-9 face the side of the clamping assembly 1.

[0054] Step 2: Arrange a certain number of flat tubes in parallel at intervals on the fixed plate 2-1 of the clamping assembly 1, and insert the two ends of the flat tubes into the gap grooves 3-9a on the corresponding core limit blocks 3-9 one by one. Then, insert a number of fins into the gaps between the two flat tubes one by one, and keep the orientations of the fins consistent.

[0055] Step 3: Place a side plate on the rear side of the last fin and the front side of the frontmost fin respectively. Then, place a side bar 6 on the rear side of the rear side plate and the front side of the front side plate respectively. Then, remove the two core limit blocks 3-9, hold the handle G on the clamping assembly 1 and rotate the handwheel F to make the movable plate 2-2 move forward and cooperate with the stop block 2-1a to clamp the fins, flat tubes, side plates and side bar 6 into a heat dissipation core A, and use a clapper board to flatten the upper edges of the fins, flat tubes and side plates.

[0056] Step 4: Start the first cylinder 3-4 on the second clamping assembly 3 through the control system, extend the piston rod of the first cylinder 3-4, place a manifold B inside the arc-shaped groove 3-5 on the second clamping assembly 3, and make one end of the manifold B abut against the corresponding first limiting plate 3-1a. Through the control system, make the piston rod of the first cylinder 3-4 on the second clamping assembly 3 retract a certain distance to clamp the manifold B inside the corresponding arc-shaped groove 3-5. Hold the handle G on the second clamping assembly 3 by hand and rotate the handwheel F to move the second movable plate 3-1 towards the corresponding core end limiting assembly 5, and use the positioning step 3-7b on the lifting vertical plate 3-7 to accurately calibrate and position the manifold B on the second clamping assembly 3. Then, through the control system, make the second cylinder 3-8 contract to lower the lifting vertical plate 3-7 below the horizontal movement track of the second movable plate 3-1, spray stamping oil on both ends of the heat dissipation core A. Continue to hold the handle G on the second clamping assembly 3 by hand and rotate the handwheel F to move the second movable plate 3-1 towards the right end of the corresponding heat dissipation core A until the manifold B is embedded in the corresponding groove at the right end of the heat dissipation core A. At this time, the right end of the flat tube is inserted into the corresponding gap on the manifold B to complete the assembly of the right end of the heat dissipation core A and the manifold B. Similarly, assemble and splice the manifold B on the third clamping assembly 4 with the left end of the heat dissipation core A (see Appendix Figure 13 );

[0057] Step 5: Start the first cylinder 3-4 on the second clamping assembly 3 and the first cylinder 3-4 on the third clamping assembly 4 through the control system, extend the piston rod of the first cylinder 3-4 to make the arc-shaped groove 3-5 larger to release the corresponding manifold B, rotate the handwheel F by holding the handle G on the second clamping assembly 3 or the third clamping assembly 4 to reset the second movable plate 3-1. Finally, use other clamping devices to unload the assembled and spliced heat dissipation core A and manifold B from the first clamping assembly 2 for subsequent processing operations.

[0058] An assembly device for a parallel flow oil cooler of the present utility model, when in use, assemble and clamp the fins, flat tubes and side plates constituting the heat dissipation core on the first clamping assembly to form the heat dissipation core, use the second clamping assembly to push the right manifold leftward and splice it into the groove at the right end of the heat dissipation core, use the third clamping assembly to push the left manifold rightward and splice it into the groove at the left end of the heat dissipation core. Compared with the traditional clamping and splicing method between the heat dissipation core and the manifold, it effectively reduces the positioning difficulty during the assembly of each component, has simple operation, and at the same time greatly reduces the manual operation difficulty and labor intensity, thus significantly improving the assembly efficiency between the heat dissipation core and the manifold, overcoming the positioning influence of human factors on each component, and effectively improving the assembly accuracy between the heat dissipation core and the manifold; the overall structure is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0059] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
