Technical Field

[0001] This utility model relates to the field of grinding auxiliary equipment, and in particular to a grinding clamp for iron pads. Background Technology

[0002] During the production process, some burrs will remain on the mold closing surface of the iron pad. At the same time, due to the draft angle, the edge will not be perpendicular. There will also be gate residue on the iron pad during casting. These burrs, bevels, and gate residue will affect normal assembly. In order to improve the surface quality of the iron pad and facilitate subsequent assembly, it is necessary to repair the iron pad and grind away the burrs and gate residue.

[0003] In order to facilitate the grinding of the iron pad, it is necessary to fix the iron pad in place. Based on this, the applicant proposes an iron pad grinding clamp. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Please combine Figures 1-3 This embodiment introduces a steel pad grinding clamp, which is mainly used to fix the steel pad and facilitate the grinding of burrs and gate residues on the steel pad.

[0037] To facilitate grinding of the iron pad, it is first necessary to secure the iron pad. This embodiment includes a base plate 1, and a leveling support plate 3 is provided to support the iron pad. The leveling support plate 3 is fixedly connected to the base plate 1 with bolts. (Refer to...) Figure 2 There are eight equal-height support plates 3.

[0038] In addition, a positioning mechanism 4 is provided on the base plate 1. The positioning mechanism 4 includes a middle positioning structure 5 and a side positioning structure 6.

[0039] Specifically, the intermediate positioning structure 5 includes an intermediate positioning seat 51 and an intermediate positioning bolt 52. The intermediate positioning seat 51 is fixedly connected to the base plate 1, and a threaded hole is provided on the intermediate positioning seat 51. The intermediate positioning bolt 52 is threaded into the threaded hole. The intermediate positioning mechanism 4 is provided in four sets, which are installed on the base plate 1 in a rectangular shape.

[0040] Similarly, the side positioning structure 6 includes a side positioning base 61 and a side positioning bolt 62. The side positioning base 61 is fixedly connected to the base plate 1. A threaded hole is provided on the side positioning base 61, and the side positioning bolt 62 is threaded into the threaded hole. Both ends of the side positioning bolt 62 extend out of the side positioning base 61. Two sets of side positioning mechanisms 4 are provided, located on both sides of the central positioning structure 5.

[0041] Additionally, a side positioning auxiliary support structure 7 is provided. The side positioning auxiliary support structure 7 includes an auxiliary support base 71 and an auxiliary support bolt 72. The auxiliary support base 71 is fixedly connected to the base plate 1, while the auxiliary support bolt 72 is threadedly connected to the replica base.

[0042] To secure the iron pad, a clamping structure 2 is provided, which includes clamps 22 and clamp base 21. The clamp base 21 is fixedly installed on the base plate 1, while the clamps 22 are vertical clamps installed on the clamp base 21.

[0043] The implementation process and principle of a grinding clamp for iron pads in this application embodiment are as follows:

[0044] Reference Figure 2 ,by Figure 2 For example, coordinates:

[0045] (1): First, place two iron pads horizontally on the equal height support plate 3. One iron pad is placed on the four equal height support plates 3 located above the x-axis, and the other iron pad is placed on the four equal height support plates 3 located below the x-axis.

[0046] (2): Make the side of the iron pad fit against the middle positioning bolt 52, and make the opposite side of the two iron pads (the side closer to the x-axis) fit against the two ends of the middle positioning bolt 52 respectively.

[0047] (3): Rotate the intermediate positioning bolt 52. The two intermediate positioning bolts 52 located above the x-axis form a group. By rotating the two intermediate positioning bolts 52, the length of the intermediate positioning bolts 52 extending out of the intermediate positioning seat 51 can be controlled. That is, the ends of the two intermediate positioning bolts 52 are in contact with the iron pad (bottom protrusion). At this time, the iron pad cannot move in the x-axis direction.

[0048] (4): Rotate the auxiliary bolt to gradually move one end of the auxiliary support bolt 72 and make it fit against the side of the iron pad. The iron pad is then clamped by the intermediate positioning bolt 52. At this time, the iron pad cannot move further in the y-axis direction.

[0049] (5): Control the clamp 22 to rotate, and the clamp 22 presses the iron pad onto the higher support plate from above. At this time, the iron pad cannot move in the height direction. This makes it convenient to grind the iron pad to remove burrs and gate residue.

[0050] Example 2:

[0051] Please combine Figures 4-6 The aforementioned intermediate positioning structure 5 has four sets, requiring two sets to be used in pairs. That is, when positioning a metal pad, the ends of the two intermediate positioning bolts 52 need to abut against the protrusions of the metal pad. This method is cumbersome, requiring the rotation of two bolts for each metal pad. Furthermore, as described in Embodiment 1, it is possible to simultaneously position and fix two metal pads. However, the above method makes it difficult to ensure complete alignment of the two metal pads (see reference). Figure 2 (in the x-axis direction). Therefore, Embodiment 2 is provided with a replacement positioning mechanism 8, which is used to replace the intermediate positioning structure 5 in Embodiment 1.

[0052] Specifically, the replacement positioning mechanism 8 includes a support frame 81, which is also fixedly connected to the base plate 1. The support frame 81 has an installation groove 82, and two spring guide rods 83 are fixedly installed in the installation groove 82.

[0053] Additionally, a drive wheel 84 is rotatably mounted in the center of the mounting slot 82. A drive shaft 85 is fixedly connected to the bottom of the drive wheel 84, and the lower end of the drive shaft 85 extends out of the mounting bracket. A diagonal connecting rod 87 is rotatably connected to the drive wheel 84, and a positioning block 86 is rotatably connected to the other end of the diagonal connecting rod 87. The positioning block 86 is T-shaped. The aforementioned spring guide rod 83 passes through the positioning block 86, and the positioning block 86 can only move along the direction of the spring guide rod 83. The other end of the positioning block 86 extends out of the side of the mounting bracket.

[0054] Therefore, when the drive shaft 85 and drive wheel 84 are rotated, the drive wheel 84 pushes the T-shaped positioning blocks 86 on both sides to move to the sides via the inclined connecting rod 87. When the iron pad is placed on the equal-height support plate 3, the two positioning blocks 86 move to the sides simultaneously, centering the iron pad. The above description can simultaneously achieve the positioning and fixing of two iron pads. Using the replacement positioning mechanism 8 in Embodiment 2, the operation is simple and can ensure that the two iron pads are aligned and positioned in the center, which is convenient for subsequent grinding, especially for machine grinding.

[0055] Additionally, the lower end of the aforementioned drive shaft 85 extends out of the mounting bracket, and a housing 10 is fitted onto the outside of the drive shaft 85, with the housing 10 fixedly connected to the support frame 81. To facilitate control of the rotation and fixation of the drive shaft 85, a handle (not shown in the figure) is first connected to the end of the drive shaft 85 for easy manual rotation. Furthermore, a fixing structure 9 is provided on the outside of the drive shaft 85. The fixing structure 9 is used to fix the drive shaft 85.

[0056] Specifically, the fixing mechanism includes a fixing cylinder 91, which is fixedly connected to one side of the housing 10 and communicates with the housing 10. A fixing rod 93 is fixedly connected inside the fixing cylinder 91, and a return spring 94 is sleeved on the outer side of the fixing rod 93. Additionally, a movable rod 95 is movably disposed inside the fixing cylinder 91. One end of the movable rod 95 has a stepped hole, and one end of the fixing rod 93 is movably installed inside the stepped hole of the movable rod 95. A movable pin 96 is also fixedly connected to the movable rod 95, and the other end of the movable pin 96 extends out of the fixing cylinder 91. A control hole 92 is also provided on the side wall of the fixing cylinder 91, along which the fixing pin can move.

[0057] Meanwhile, a fixing hole 11 is provided on the drive shaft 85. When the movable rod 95 is pushed to move by the movable pin 96, one end of the movable rod 95 extends out of the fixing cylinder 91 and into the fixing hole 11 on the drive shaft 85, at which time the drive shaft 85 cannot rotate.

[0058] Conversely, the movable pin 96 drives the movable rod 95 away from the drive shaft 85, at which point the return spring 94 is compressed. The drive shaft 85 can then rotate freely.

[0059] The implementation process and principle of Embodiment 2 of this application are as follows:

[0060] (1) After placing the iron pad on the equal-height support plate 3, control the drive shaft 85 to rotate. When the drive shaft 85 drives the drive wheel 84 to rotate, the inclined connecting rod 87 on the drive wheel 84 pushes the positioning block 86 to move to both sides at the same time. The two positioning blocks 86 gradually approach and fit the bottom protrusion of the iron pad, and center the iron pad. The movement process of the positioning block 86 is simple to operate and can ensure that the two iron pads are aligned and positioned in the center, which is convenient for subsequent grinding, especially for machine grinding.

[0061] (2): When the movable rod 95 is moved by the movable pin 96, one end of the movable rod 95 extends out of the fixed cylinder 91 and into the fixed hole 11 on the drive shaft 85. At this time, the drive shaft 85 cannot rotate. The drive plate and the positioning block 86 are fixed and cannot continue to move, thus preventing the iron pad from moving during grinding.

[0062] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
