Description

Technical Field

[0001] This utility model belongs to the field of centering and clamping mechanisms, and relates to a high-precision centering and positioning mechanism and assembly equipment for flat products. Background Technology

[0002] For example, Chinese patent literature discloses an automatic centering mechanism for automobile steering knuckles [201520467882.2], which includes a support base, on which a clamping mechanism and a driving mechanism are mounted. The clamping mechanism includes two clamping heads arranged opposite each other, a reset member is arranged between the two clamping heads, and a positioning shaft is arranged on the opposite surface of the two clamping heads. The driving mechanism and the reset member cooperate to drive the opening and closing of the two clamping heads.

[0003] The drawbacks of the above technical solution are: the drive structure is located below the support base, which still occupies a lot of three-dimensional space. At the same time, the vertical drive method is not easy to eliminate the influence of gravity, and the clamping force remains uneven, which leads to a decrease in accuracy after long-term use. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a high-precision centering and positioning mechanism and assembly equipment for flat panel products.

[0005] The objective of this utility model can be achieved through the following technical solutions: The high-precision centering and positioning mechanism for the flat panel product includes: The machine has product support columns spaced apart in the middle. The clamping assembly includes clamping blocks arranged symmetrically in pairs and slidably connected to both sides of the machine table along the width direction of the machine table, and an elastic element is provided on the machine table that acts on the clamping blocks and forces the clamping blocks away from the product support column. The drive assembly includes an abutting inclined surface disposed on the side of the clamping block away from the elastic member, first drive sliders disposed on both sides of the machine tool and slidably disposed along the length of the machine tool, second drive parts disposed on one side of the first drive sliders and acting on the abutting inclined surface of the clamping block on the same side, and a third drive rod connected at both ends to the middle of the two second drive parts.

[0006] Furthermore, the machine tool is also provided with a first slide rail that is slidably connected to the first drive slider, and a return limit block is provided at one end of the first slide rail.

[0007] Furthermore, the machine base is provided with a second slide rail that is slidably connected to the clamping block, and a clamping limit block is provided at one end of the second slide rail near the product support column.

[0008] Furthermore, the elastic element is disposed between the clamping limiting block and the clamping block, and the clamping limiting block is provided with a guide blind hole for one end of the elastic element to be inserted.

[0009] Furthermore, one end of the clamping block is provided with a clearance notch into which one end of an elastic element extends.

[0010] Furthermore, the machine tool has an installation notch in the middle, and the installation notch is equipped with a driver connected to the middle of the third drive rod, and the middle of the third drive rod has a U-shaped segment that is recessed downwards.

[0011] Furthermore, the clamping block has a protruding pointed end at one end near the product support column.

[0012] Furthermore, the second driving part is a driving slope that protrudes from one side of the first driving slider and is in contact with the abutting slope.

[0013] Furthermore, the second driving part is a driving roller hinged to the clamping block, and the circumferential outer wall of the driving roller rolls into contact with the abutting inclined surface.

[0014] This utility model also provides an assembly device having a high-precision centering and positioning mechanism for flat products as described above.

[0015] Compared with existing technologies, the high-precision centering and positioning mechanism of this flat panel product places all the driving components above the machine tool and arranges them horizontally at intervals, reducing space occupation and avoiding the influence of gravity.

Detailed Implementation

[0021] Example 1, please refer to Figures 1 to 3 This is a schematic diagram of a high-precision centering and positioning mechanism for a flat panel product provided by this utility model. The high-precision centering and positioning mechanism for the flat panel product includes: a machine base 10; a clamping assembly 20 and a driving assembly 30 for driving the clamping assembly 20 are provided on the machine base 10. It is conceivable that this high-precision centering and positioning mechanism for the flat panel product also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, all of which are well-known to those skilled in the art, and therefore will not be described in detail here.

[0022] In this embodiment, the product is a rectangular flat plate structure with a recessed mounting groove in the center of the bottom.

[0023] In this embodiment, the upper end of the machine base 10 is a flat surface, which serves as the mounting carrier and is typically set on the equipment platform. Four product support columns 11 are spaced apart in the middle of the machine base 10. Depending on the exposed surface requirements of the product, the product can be placed on the product support column 11, or the product's mounting slot can be inverted onto the product support column 11. This lowers the product's center of gravity on the product support column 11, resulting in more stable installation and placement.

[0024] In this embodiment, the clamping assembly 20 includes clamping blocks 21 slidably connected to both sides of the machine base 10 along its width direction. Two clamping blocks 21 are spaced apart on each side of the machine base 10, and the clamping blocks 21 on both sides of the machine base 10 are symmetrically arranged in pairs. The machine base 10 is also provided with a second slide rail 23 slidably connected to the clamping blocks 21. The second slide rail 23 provides motion guidance for the clamping blocks 21, and the clamping blocks 21 move along the slide rail to achieve four-point symmetrical clamping of both sides of the product. Specifically, the end of the clamping block 21 near the product support column 11 has a protruding pointed end 27. The pointed end 27 has a T-shaped cross-section, and its outer diameter gradually decreases outward axially. The pointed end 27 reduces the contact area between the clamping block 21 and the product, which facilitates reducing torsional damage between the clamping block 21 and the outer wall of the product during centering adjustment.

[0025] Two clamping and limiting blocks 24 are provided at one end of the first slide rail 35 near the product support column 11 to prevent the clamping blocks 21 from excessively abutting against the outer wall of the product. An elastic element 22, which is a spring, is provided on the clamping and limiting blocks 24 to act on the clamping blocks 21. The elastic elements 22 apply force to the clamping blocks 21 on both sides, forcing the clamping blocks 21 away from the product support column 11, thus providing clamping buffering and return functions. A guide blind hole 25 is provided on the clamping and limiting blocks 24 for one end of the elastic element 22 to be inserted. The guide blind hole 25 provides elastic deformation guidance for the elastic element 22, reducing the error in the buffering force of the four clamping blocks 21. Optimally, one end of the clamping block 21 is provided with a clearance notch 26 into which one end of the elastic element 22 extends, making the connection point between the elastic element 22 and the clamping block 21 closer to the center point of the clamping block 21, reducing its own offset problem.

[0026] In this embodiment, the drive assembly 30 includes an abutment slope 31 disposed on the side of the clamping block 21 away from the elastic member 22, first drive sliders 32 slidably disposed on both sides of the machine base 10 along the length of the machine base 10, second drive parts 33 acting on the abutment slope 31 of the clamping block 21 on the same side spaced apart on one side of the first drive sliders 32, and a third drive rod 34 connected at both ends to the middle of the two second drive parts 33. The third drive rod 34 is connected to a driver 37, which is a cylinder. The connection between the output end of the driver 37 and the third drive rod 34 is located at the center point between the four clamping blocks 21. The center point drive applies force, and the four-point symmetrical clamping method improves the uniformity of force for centering and clamping the product, improves the synchronization of the dual-side drive, and improves the centering accuracy during long-term use.

[0027] In this embodiment, the machine base 10 has a mounting notch 12 in the middle, and the mounting notch 12 is equipped with a driver 37 connected to the middle of the third drive rod 34. This provides sufficient space for the driver 37 to be installed and facilitates the routing of the driver 37's wiring. All drive components are positioned above the machine base 10 and spaced horizontally, reducing space occupation and avoiding the influence of gravity. The U-shaped segment 38 recessed downward in the middle of the third drive rod 34 serves to facilitate product positioning, making the installation structure more compact.

[0028] The machine tool 10 is also provided with a first slide rail 35 that is slidably connected to the first drive slider 32. The first slide rail 35 is provided with a return limit block 36 at one end. The return limit block 36 restricts the sliding of the first sliding drive and prevents the first drive slider 32 from sliding off the first slide rail 35.

[0029] In this embodiment, the second driving part 33 is a driving roller 331 hinged on the clamping block 21. The circumferential outer wall of the driving roller 331 rolls into contact with the abutting inclined surface 31. The contact area between the driving roller 331 and the abutting inclined surface 31 is small and is rolling friction, so the driving is smoother and the force-bearing effect is better.

[0030] Please see Figure 4 In other embodiments, the second driving part 33 is a driving inclined surface 332 that protrudes from one side of the first driving slider 32 and is in contact with the abutting inclined surface 31. The driving inclined surface 332 and the abutting inclined surface 31 are interleaved and overlapped, which achieves the same driving effect as the roller.

[0031] Example 2: This utility model also provides an assembly device with a high-precision centering and positioning mechanism for flat products as described above. Except for the high-precision centering and positioning mechanism for flat products, the other components are all existing technologies or commercially available parts, and will not be described in detail here.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
