Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing, and in particular relates to a buffer spring sheet assembly device. Background Art

[0002] The buffer assembly in a certain product's firing device consists of a buffer cylinder, a clamp, a buffer spring sheet, and a buffer rod. During assembly, the buffer spring sheet needs to be installed into the buffer rod. The direction of the spring is in a positive and negative corresponding form. Four pieces form a group, and the assembly sequence and quantity must be guaranteed. The current assembly process is to manually calculate the quantity, and the assembly direction of the spring also needs to be manually adjusted. Since each buffer cylinder needs to be installed with 40 sets of spring sheets, a total of 160 pieces, additional installation is required when necessary.

[0003] Each product contains one buffer. More than 300 buffers need to be produced throughout the year. Each buffer needs to be assembled with 160 spring leaves, which is characterized by large quantity and high labor intensity. In the original manual assembly process, the probability of error in the number of buffer spring leaves is 5%, and the probability of error in assembly direction is 12%. If there is a problem in the test, the buffer needs to be disassembled and reassembled, which wastes time and increases the intensity of the operator. There are problems such as wrong assembly and missing assembly during the assembly process, which affect product performance. Utility Model Content

[0016] The following description sufficiently illustrates specific embodiments of the present invention to enable those skilled in the art to practice and reproduce the same.

[0017] like Figure 1 The figure is a schematic diagram of the structure of the buffer spring sheet assembly device in the utility model.

[0018] The buffer spring sheet assembly device comprises: a spring sheet 1, a fixing block 4, and a bottom plate 5, wherein the fixing block 4 is provided with a mounting groove, and the spring sheet 1 is mounted in the mounting groove; a plurality of fixing blocks 4 are connected to the top of the bottom plate 5, and the fixing blocks 4 are fixed to the bottom plate 5 by screws and cylindrical pins;

[0019] The bottom of the fixed block 4 is provided with a baffle 51, and pads 52 are provided on both sides to prevent the spring sheet 1 from moving. The baffle is fixed to the fixed block by screws. The baffle 51 is used to fix the position of the spring sheet 1, and is fixed to the fixed block 4 by a hexagon socket head screw 1 to prevent the spring sheet 1 from sliding from both sides during assembly. The baffle 51 prevents the spring sheet 1 from moving when not in operation, and the pads 52 are used to eliminate the gap between the fixed blocks to prevent the spring sheet 1 from moving during assembly.

[0020] The mounting groove of the fixing block 4 is designed according to the structure of the spring sheet 1 and is divided into positive and negative directions for symmetrical mounting of the spring sheet 1 in the positive and negative directions.

[0021] The buffer rod 3 passes through the inner hole of the spring sheet 1 to form a spring sheet group; the buffer tube 2 is sleeved on the outside of the spring sheet group, and the buffer tube 2 is fixed in the installation groove to further fix the spring sheet 1.

[0022] like Figure 2 As shown, it is a schematic diagram of the fixing block 4 installed on the bottom plate 5 in the utility model; Figure 3 As shown, Figure 2 A top view of Figure 4 As shown, Figure 2 Side view of.

[0023] Hexagon socket head screws are arranged on both sides of the bottom plate 5 .

[0024] Installation grooves are opened on the fixing block 4. According to the forward and reverse assembly order, each installation groove can be installed with 4 spring leaves, and the installation direction is symmetrical (only 4 spring leaves 4 can be installed in the installation groove to ensure that there are no missed installations or excessive installations). Each fixing block 4 can be equipped with 40 spring leaves 4. 4 fixing blocks 4 can ensure the assembly of 160 spring leaves, avoiding wrong installation and missed installation, and meeting the product assembly requirements.

[0025] The pad 5 is used to fill the gap between each group of fixing blocks 4 to prevent the spring sheet 4 from sliding left and right during the assembly process, thereby affecting the assembly quality.

[0026] Example 1

[0027] The material of the spring sheet 1 is 60Si2MnA, with a hardness of 45.5-51.5HRC. To ensure the spring force required by the product, the spring sheet 1 of the buffer is composed of 4 sheets per group, and the number of groups is not less than 40. During assembly, 4 spring sheets 1 are grouped into 1 group, and the grouped spring sheets 1 are directly sleeved on the buffer rod. It is necessary to ensure that the spring sheets 1 are installed as a set, and each group of spring sheets is installed symmetrically in the positive and negative directions during assembly, so that each buffer rod finally has 40 groups of spring sheets.

[0028] Use working process:

[0029] 1. Place the assembly tool on the assembly platform, and insert the spring sheet 1 into the installation groove according to the requirements of each group of 4 spring sheets 1. Each fixed block 4 has 5 groups of installation grooves on the front and back sides, corresponding to the 5 groups of spring sheets on the front and back sides.

[0030] 2. Since the installation groove is symmetrical, the assembly direction of the spring piece 1 is also symmetrical to avoid wrong installation. Each fixing block 4 is installed with 10 groups of spring pieces 1, and 40 groups of spring pieces 1 are installed in total with 4 fixing blocks.

[0031] 3. Insert the spring sheet 1 into the corresponding installation slot of the fixing block 2, and use screws to fix Figure 3 The baffle plate 3 in the middle is fixed on the fixed block 2 to prevent the spring sheet 1 from sliding to both sides.

[0032] 4. Insert the backing plate 51 into the gap of the fixing block 4 to prevent the spring sheet 1 from sliding forward and backward and to fix the spring sheet 1.

[0033] 5. The buffer rod 3 is along the direction of the spring sheet 1 of the fixed block 4, and the buffer rod 3 passes through the driving spring sheet group along the inner hole of the spring sheet 1, so that the spring sheet 1 can be sleeved on the buffer rod 3, and so on, and finally all 40 groups of spring sheets 1 can be sleeved on the buffer rod 3.

[0034] 6. The assembly tool can realize the function of assembly error prevention, effectively avoid the problems of wrong installation direction of spring leaves, insufficient installation quantity, etc., reduce the labor intensity of operators, and improve the qualified rate of one-time assembly.
