Description

Technical Field

[0001] This utility model belongs to the field of side-press tooling technology, and specifically relates to an assembly fixture for side-press fitting on a vertical assembly machine. Background Technology

[0002] In the field of mechanical manufacturing, vertical assembly machines use vertical driving force to achieve vertical pressing of parts, and are widely used in mass assembly in industries such as automobiles and electronics. However, for some parts with side wings and radial clips, lateral force must be applied simultaneously to ensure accurate assembly and avoid misalignment or tilting.

[0003] Traditional processes employ a step-by-step approach: first, vertical positioning is performed, followed by manual or multi-station lateral pressing, which has significant drawbacks. Step-by-step processing extends the assembly cycle and makes it difficult to meet high-speed production requirements; when manually applying lateral force, the force and timing depend on experience, which can easily lead to insufficient accuracy and workpiece damage; multi-station collaboration requires additional equipment and transfer mechanisms, increasing costs and floor space, and may also introduce secondary positioning errors. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An assembly fixture for lateral pressing on a vertical assembly machine includes a lower pressing assembly, a side pressing assembly, and a pre-fixing assembly. Two sets of side pressing assemblies are symmetrically installed on both sides of the pre-fixing assembly. The lower pressing assembly includes a lifting push plate, and the side pressing assembly includes a slider. A side pressing block is installed inside the slider. The push plate descends and pushes the slider to move toward the pre-fixing assembly. The side pressing block presses the blank on the pre-fixing assembly.

[0007] Preferably, the pressing component includes a pressing block that moves up and down synchronously with the push plate, and the pre-fixing component includes a contour positioning block.

[0011] Preferably, a second elastic element is installed between the slider and the pre-fixing component. When the push plate is pressed down, the slider slides toward the pre-fixing component, and the second elastic element is compressed. When the push plate is raised, the slider slides away from the pre-fixing component under the action of the second elastic element.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1

[0024] refer to Figures 1 to 5 The assembly fixture for lateral pressing on a vertical assembly machine described in this embodiment includes a base plate 3, a lower pressing component 1, a side pressing component 2, and a pre-fixing component 4. Both the side pressing component 2 and the pre-fixing component 4 are mounted on the base plate 3. Two sets of side pressing components 2 are symmetrically mounted on both sides of the pre-fixing component 4. The lower pressing component 1 includes a lifting push plate 16. The side pressing component 2 includes a slider 23. A side pressing block 24 is installed inside the slider 23. The push plate 16 descends and pushes the slider 23 to move towards the pre-fixing component 4. The side pressing block 24 presses the blank on the pre-fixing component 4.

[0025] Preferably, the pressing assembly 1 includes an upper plate 11 and a pressure plate 12. The upper plate 11 is mounted on the output end of the hydraulic press. Multiple sets of push plates 16 are fixedly mounted on the upper plate 11. Two sets of guide rods 15 are mounted on the bottom end of the upper plate 11. The guide rods 15 are slidably connected to the pressure plate 12. A first elastic element 14 is installed between the pressure plate 12 and the upper plate 11. When the upper plate 11 is pressed down, the first elastic element 14 is compressed. The first elastic element 14 provides a certain descent space for the pressure plate 12 to accommodate product tolerances and avoid the pressure plate 12 not pressing tightly enough, causing processing deviations and affecting processing accuracy.

[0026] Preferably, the pressing component 1 includes a pressing block 13 that moves up and down synchronously with the push plate 16. The pressing block 13 is installed at the bottom of the pressure plate 12. The pre-fixing component 4 includes a contour positioning block 42 installed on the base plate 3. The contour positioning block 42 and the pressing block 13 are set according to the shape to be processed according to actual needs. The pressing block 13 presses down to cooperate with the contour positioning block 42 to process the top and bottom of the blank.

[0027] Preferably, the pre-fixed component 4 includes two sets of placement columns 45, which are located on both sides of the contour positioning block 42. The blank is fixedly installed on the placement columns 45 by fixing bolts 44. The pressure plate 12 on the outer side of the lower pressure block 13 is provided with corresponding receiving holes 43 for accommodating the fixing bolts 44, so as to fix the blank and avoid the blank from shifting during processing, causing processing position errors and reducing the quality of the finished product.

[0028] Preferably, the pre-fixed component 4 includes a fixed side plate 41. The top of the fixed side plate 41 is designed with a reasonable shape according to the actual processing needs. During processing, the side end of the blank is clamped between the side pressure block 24 and the fixed side plate 41 to process the required shape.

[0029] The slider 23 is equipped with slide rails 21 on both its front and rear sides, and the slider 23 is slidably connected to the slide rails 21. A limiting plate 22 for limiting the slider 23 is installed at the end of the slide rail 21 away from the contour positioning block 42. A second elastic element 27 is installed between the slider 23 and the fixed side plate 41. When the push plate 16 is pressed down, the slider 23 slides towards the fixed side plate 41 to bend the blank, at which time the second elastic element 27 is compressed. When the push plate 16 is raised, the slider 23 slides along the slide rail 21 away from the fixed side plate 41 under the action of the second elastic element 27 and is limited and stopped by the blocking of the limiting plate 22 to prevent derailment.

[0030] The slider 23 has symmetrical sides, each including an inner plate 231 and an outer plate 232. The outer plate 232 is slidably connected to the slide rail 21. A rotating shaft 25 is rotatably mounted between the inner plate 231 and the outer plate 232. The length direction of the rotating shaft 25 is perpendicular to the moving direction of the slider 23, and the slider 23 is close to the fixed side plate 41. The push plate 16 is inserted between the rotating shaft 25 and the slider 23.

[0031] Preferably, a rotating sleeve 26 is fitted onto the rotating shaft 25. The rotating sleeve 26 is made of an elastic material to protect the rotating shaft 25 and the push plate 16 and reduce damage.

[0032] Preferably, the bottom end of the push plate 16 is an inclined surface that gradually rises near the fixed side plate 41.

[0033] Multiple sets of positioning guide posts 5 are installed at the bottom of the upper plate 11, and multiple sets of positioning guide sleeves 6 are installed on the bottom plate 3. When the upper plate 11 is pressed down for processing, the positioning guide posts 5 and the positioning guide sleeves 6 are interference-fitted.

[0034] Working principle:

[0035] Before processing, the blank is placed on the contour positioning block 42, and both ends of the blank are placed on the fixed side plate 41. The fixing bolt 44 is passed through the blank and fixedly installed on the placement column 45. At this time, the first elastic element 14 and the second elastic element 27 are not under force, and the slider 23 abuts against the limiting plate 22.

[0036] During processing, the upper plate 11 presses down, causing the push plate 16 and the pressure plate 12 to press down, and the first elastic element 14 is gradually compressed. The pressure plate 12 causes the lower pressure block 13 to press down together with the contour positioning block 42 to press out the required shape. The push plate 16 abuts against the rotating sleeve 26, which in turn pushes the rotating shaft 25 to drive the slider 23 to move closer to the center along the slide rail 21. The side pressure block 24 on the slider 23 processes the side of the blank. At this time, the second elastic element 27 is gradually compressed.

[0037] After processing, the upper plate 11 rises, the first elastic element 14 gradually returns to its original shape, the force of the push plate 16 on the rotating shaft 25 gradually disappears, and the rebound of the second elastic element 27 pushes the slider 23 to move to both sides along the slide rail 21 until it is blocked by the limit plate 22. The finished product can be taken out by removing the fixing bolt 44.

[0038] This machining fixture positions and processes both the side and front sides simultaneously, avoiding the impact of multiple fixings on machining accuracy. It also saves time and labor costs associated with transfers, resulting in high machining efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
