Description

A thimble polishing jig

technical field

The utility model relates to the technical field of metal accessories processing tools, in particular to a thimble polishing fixture.

Background technique

In the processing of metal parts, metal parts such as thimbles are usually formed by direct casting. For the first use, the shaft surface of the thimble needs to be polished. The thimble used in the plastic mold generally has a variety of specifications, and after the thimble has been used for a period of time, the surface of the shaft body needs to be re-polished. The thimbles used in plastic molds are small in number and have different specifications. Therefore, the existing plastic mold processing workshops usually use manual operations to polish each thimble in a complete set of plastic molds separately, and the processing efficiency is low.

Contents of the invention

The purpose of the utility model is to propose a thimble polishing jig with high processing efficiency and low cost.

The thimble polishing jig provided according to the utility model includes a jig body, the key is that the end face of the jig body is provided with a plurality of parallel grooves, the cross section of the groove is triangular, and the depth of the groove is along the length of the jig body. The longitudinal direction of the clamping body is arranged gradually, and the end surface of the clamp body is also provided with a clamping block, and the clamping block has a clamping plane, and the clamping plane covers the openings of the plurality of grooves.

The thimble polishing jig of the utility model, when in use, put multiple thimbles in the complete set of plastic molds into the matching grooves on the end surface of the fixture body according to the diameter, and then install the clamping block to position the thimbles in the grooves Inside, the shaft surface of the thimble can be polished by the grinding wheel, which is very convenient and quick; the thimble is positioned in the groove, but the rotation of the thimble itself is not restricted, so the thimble itself can be on the grinding wheel during the process of polishing the shaft surface of the thimble. Rotate under the friction of the shaft to complete the overall polishing of the shaft surface; the depth of the grooves is arranged gradually, so that the diameters of the rows of thimbles positioned by the fixture can be arranged from small to large along the grinding direction of the grinding wheel, especially suitable for the current handle-type pressing This is due to people's habits. When using a handle-type press-down grinder, when the grinding wheel is pressed down with the handle, when it first touches the thimble with a smaller diameter in the front, the downward pressure during contact is The minimum, and then with the further pressing down of the grinding wheel, the fixture is pushed forward, so that the greater pressure of the grinding wheel corresponds to the polishing of a larger diameter thimble, thereby improving the polishing quality of the thimble.

Further, the side wall of the fixture body is provided with markings below the groove. Since the thimble in the complete set of plastic molds is generally provided with a corresponding label, the side wall of the fixture body is located below the groove to set the same label as the label, and the thimble removed from the mold can be directly put into the groove of the fixture body ,Improve work efficiency.

Detailed ways

Below with reference to the accompanying drawings, through the description of the implementation examples, the specific embodiments of the present utility model, such as the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part, etc. Further details.

As shown in Figures 1, 2, and 3, the thimble polishing fixture of the present utility model includes a fixture body 1. The end surface of the fixture body 1 is provided with a plurality of grooves 11 arranged in parallel. The cross section of the groove 11 is triangular, and the depth of the groove 11 is Arranged gradually along the length direction of the clamp body 1 , the end surface of the clamp body 1 is also provided with a clamping block 2 , the clamping block 2 has a clamping plane 21 covering the opening of the groove 11 . Wherein, the clamping block 2 is generally installed through bolts 20 .

The thimble polishing jig of the utility model, when in use, put multiple thimbles in the complete set of plastic molds into the groove 11 on the end surface of the fixture body 1 according to the diameter, and then install the clamping block 2 to position the thimbles In the groove 11, the shaft surface of the thimble can be polished by the grinding wheel, which is very convenient and fast; the thimble is positioned in the groove 11, but the rotation of the thimble itself is not restricted, so during the process of polishing the shaft surface of the thimble with the grinding wheel, The thimble itself can rotate under the friction of the grinding wheel to complete the overall polishing of the shaft body surface; the depth of the groove 11 is arranged gradually, so that the diameters of the rows of thimbles positioned by the fixture can be arranged from small to large along the grinding direction of the grinding wheel, especially suitable for current This is due to people's habits. When using a handle-type press-down grinder, when pressing the grinding wheel down with the handle, it first touches the thimble with a smaller diameter in front, and then touches the thimble with a smaller diameter. The downward pressure is the minimum, and then with the further force of the grinding wheel, the fixture is pushed forward, so that the greater pressure of the grinding wheel corresponds to the polishing of a larger diameter thimble, thereby improving the polishing quality of the thimble.

As a preferred embodiment, the side wall 12 of the fixture body 1 is located below the groove 11 and is provided with a reference numeral 13 . Since the thimble in the complete set of plastic molds is generally provided with a corresponding label, the side wall 12 of the fixture body 1 is located below the groove 11 and the same label as the label is set, and the thimble removed from the mold can be directly put into the fixture body 1 In the groove 11, work efficiency is improved.
