Description

Technical Field

[0001] This utility model relates to the field of honing technology, and in particular to a single-hole vertical honing fixture. Background Technology

[0002] When machining cylinder bores with short shaft diameters, a vertical honing machine is generally used. This type of single-hole cylinder bore has a small machining allowance and a short honing time, so the clamping speed determines the machining efficiency.

[0003] The existing vertical honing machine clamping fixture uses an angle wrench in conjunction with the clamping platform. The clamping platform is tilted, and after the bottom of the cylinder hole is flat against the clamping platform, pads are placed on the columns on both sides of the cylinder hole to press the cylinder hole. Then the angle is adjusted to the correct position. This method is time-consuming and cumbersome, and has low efficiency for processing large batches of cylinder holes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a single-hole vertical honing fixture that is suitable for workpieces of various sizes and has high clamping efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a single-hole vertical honing fixture, which includes a pressure plate and a base plate. The base plate is provided with a sliding plate that can slide back and forth, and a slide rail for guiding the sliding plate to slide back and forth. Both the base plate and the sliding plate are provided with through holes for the workpiece to pass through. A three-jaw chuck is installed on the upper surface of the sliding plate. There is a vertical pressure rod on each side of the sliding plate. Multiple pressure rod sleeves are fitted on the pressure rods. The pressure rod sleeves are tapered sleeves that are thinner at the top and thicker at the bottom. Each pressure rod sleeve is fitted from bottom to top in such a way that the thick end of the upper pressure rod sleeve is fitted with the thin end of the adjacent lower pressure rod sleeve. The thick end of the first pressure rod sleeve is fitted with the upper end of the pressure rod. The pressure plate has a honing opening in the middle for the honing head to pass through. The pressure plate has a mounting hole on the left and a mounting hole on the right. The honing opening is located between the two mounting holes. The thin ends of the pressure rod sleeves at the top of the two pressure rods are inserted into the two mounting holes in a movable fit manner.

[0006] Furthermore, a cylinder is installed on the base plate to drive the sliding plate to slide back and forth.

[0007] Furthermore, the narrow end of the pressure rod sleeve is threaded, and the pressure plate is fixed to the pressure rod sleeve by a nut.

[0008] Furthermore, a notch is provided on the left side of the pressure plate, which communicates with the mounting hole on the left side of the pressure plate, so that the pressure rod sleeve in the left mounting hole can be disengaged from the pressure plate through the notch.

[0009] The single-hole vertical honing fixture provided by this utility model uses a slide rail to adjust the movement of the workpiece between the clamping station and the honing station, which facilitates clamping. It uses a three-jaw chuck and a pressure plate to fix the workpiece in place, which can quickly clamp workpieces of various sizes and has high clamping efficiency. Attached Figure Description

[0010] Figure 1 This is a structural schematic diagram of a single-hole vertical honing fixture according to an embodiment of the present invention. Detailed Implementation

[0011] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and.

[0012] like Figure 1 As shown in the figure, the single-hole vertical honing fixture provided in this embodiment of the present invention includes a pressure plate 6 and a base plate 1. The base plate 1 is provided with a sliding plate 3 that can slide back and forth, and a slide rail 2 for guiding the sliding plate 3 to slide back and forth. Both the base plate 1 and the sliding plate 3 are provided with through holes for the workpiece to pass through. A three-jaw chuck 8 is installed on the upper surface of the sliding plate 3. A vertically placed pressure rod 4 is fixed on the left and right sides of the sliding plate 3. Multiple pressure rod sleeves 5 are sleeved on the pressure rod 4. The pressure rod sleeve 5 is a tapered sleeve that is thinner at the top and thicker at the bottom. Each pressure rod sleeve 5 is sleeved from bottom to top in such a way that the thick end of the upper pressure rod sleeve is sleeved with the thin end of the adjacent lower pressure rod sleeve. The thick end of the first pressure rod sleeve 5 is sleeved with the upper end of the pressure rod 4. The pressure plate 6 has a honing opening 61 in the middle for the honing head to pass through. The pressure plate 6 has a mounting hole on the left and a mounting hole on the right. The honing opening 61 is located between the two mounting holes. The thin ends of the pressure rod sleeves 5 at the top of the two pressure rods 4 are inserted into the two mounting holes in a movable fit manner.

[0013] In this embodiment of the present invention, a cylinder 7 for driving the sliding plate 3 to slide back and forth is installed on the base plate 1; The pressure plate 6 has a notch 62 on its left side, which is connected to the mounting hole on the left side of the pressure plate 6, so that the pressure rod sleeve 5 in the left mounting hole can be disengaged from the pressure plate 6 through the notch 62. The thin end of the pressure rod sleeve 5 is threaded, and the pressure plate 6 is fixed to the pressure rod sleeve 5 by a nut.

[0014] The device provided in this embodiment of the invention is suitable for single-hole vertical honing. When using the fixture, install it on the work platform. When clamping the workpiece, start the cylinder 7 to drive the sliding plate 3 to move to the clamping position, loosen the nut on the top of the pressure plate 6, and screw the pressure plate 6 outward through the concave hole 62. Then, put the workpiece into the three-jaw chuck 8 and clamp and fix the workpiece. Rotate the pressure plate 6 back to its original position. After tightening the nut on the top of the pressure plate 6, start the cylinder 7 to drive the sliding plate 3 to move to the honing position for processing. Depending on the workpiece height, the number of pressure bar sleeves 5 can be increased or decreased to match the height of the pressure plate 6 with the workpiece.
