Description

Technical Field

[0001] The present utility model relates to the technical field of tooling, and in particular to a fixing tool for bracket grinding. Background Art

[0002] Bracket-type workpieces are common basic components in the field of mechanical manufacturing, and the grinding quality of their mounting holes directly affects subsequent assembly accuracy, connection stability and appearance consistency. Therefore, the bracket needs to be strictly fixed and limited during the grinding process. However, there are still many technical defects in the current fixing methods for bracket grinding in the industry, which are difficult to meet the processing requirements of high precision and high efficiency: Existing fixing tools mostly adopt planar clamping or single pin positioning, which cannot adapt to the irregular contour of the bracket. Especially for brackets with arc-shaped or special-shaped side edges, it is difficult to achieve accurate lateral positioning, which easily causes the bracket to generate horizontal displacement perpendicular to the grinding direction, resulting in dimensional deviation of the grinding surface and even workpiece scrap.

[0020] like Figure 1-4 As shown, this utility model provides a fixing fixture for grinding brackets, including a base 1, a positioning seat 2, a fixing seat 3 and a limiting component 4. The positioning seat 2 and the fixing seat 3 are respectively located on both sides of the base 1 and the bracket 5 is placed between them. The base 1 is provided with through holes 11 corresponding to the mounting holes on the bracket 5. In addition, the positioning base 2 includes a connecting plate 21 and a positioning plate 22. The connecting plate 21 is connected to the chassis 1 by screws. The positioning plate 22 is located inside the connecting plate 21 and has a V-groove 23. The clamping characteristics of the V-groove are used to achieve the initial lateral positioning of the bracket 5 and avoid the horizontal displacement of the bracket 5 along the direction perpendicular to the grinding. The fixing seat 3 is connected to the chassis 1 by screws. The fixing seat 3 has an "L" shaped structure and a mounting seat 31 is provided on its outer side.

[0021] In addition, the fixed base 3 is provided with a limiting component 4 for fixing the bracket 5. The limiting component 4 includes a pressure plate 41, a sleeve 45 and a threaded rod 46. The pressure plate 41 has a "U" shaped structure and its opening faces downward. Support plates 42 are provided at both ends of the top of the pressure plate 41. Threaded rods 43 are symmetrically provided on both sides of the mounting base 31. The two threaded rods 43 are connected to the corresponding support plates 42 by nuts. The bottom of each support plate 42 is also provided with a guide rod 44 that slides into the mounting base 31 to ensure that the pressure plate 41 does not shift during movement and always maintains parallelism with the fixed base 3 and the bracket 5. Meanwhile, two sleeves 45 are provided and symmetrically arranged on both sides of the pressure plate 41, and two threaded rods 46 are provided and respectively pass through the positioning holes on the fixed seat 3 and the bracket 5 and the sleeves 45 and are connected to the pressure plate 41 by nuts.

[0022] Detailed implementation methods and principles: Place the bracket 5 to be ground in the area of ​​the chassis 1 between the positioning seat 2 and the fixed seat 3, so that one side of the bracket 5 fits the V-groove of the positioning plate 22 of the positioning seat 2. The clamping characteristics of the V-groove are used to achieve the initial lateral positioning of the bracket 5. At the same time, the mounting hole on the bracket 5 is aligned with the preset through hole 11 on the chassis 1. Then, the two support plates 42 on the pressure plate 41 are respectively sleeved on the threaded rod 43. At the same time, the guide rod 44 at the bottom of the support plate 42 is slidably inserted into the mounting seat 31. The two sides of the pressure plate 41 press on the bracket 5, and the nut on the threaded rod 43 is rotated to lock it. Then, the two threaded rods 46 pass through the fixed seat 3, the positioning hole on the bracket 5 to be ground, and the sleeves 45 on both sides of the pressure plate 41 respectively, and are locked with the pressure plate 41 by the nut. That is, the bracket 5 is finally tightened by the limiting component 4. The operator can then grind the part of the bracket 5 to be ground.
