Description

Technical Field

[0001] This utility model belongs to the technical field of precision surface treatment machine tools, and more specifically, relates to an indexing method suitable for precision surface treatment machine tools. Background Technology

[0002] Machine tool indexing is a device used on machine tools to rotate and position workpieces or tools. It is one of the key equipment for precision machining. Since the indexing of machine tools is rotating, there is always a certain gap. If the gap is large, the overall load will be small, while if the gap is small, it is easy to cause wear between the indexing plate and the base, resulting in a short service life of the indexing plate. Utility Model Content

[0003] The present invention aims to provide an indexing method suitable for precision surface treatment machine tools, thereby solving at least one of the problems in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0005] An indexing method suitable for a precision surface treatment machine tool according to a first aspect embodiment of the present invention includes:

[0006] Indexing plate;

[0007] A rotating shaft, which is perpendicular to the indexing plate and fixedly connected to the axis of the indexing plate;

[0008] The first driving device drives the indexing plate to rotate at different angles around the rotation axis;

[0009] A first locking mechanism, the first locking mechanism including

[0010] Second hydraulic cylinder;

[0011] The first pressing member has its upper end fixedly connected to the output shaft of the second oil cylinder, and its lower end is provided with a first locking groove.

[0012] A plurality of first locking rods are fixedly connected to the indexing plate. The first pressing member is driven by the second hydraulic cylinder, so that the first locking groove is engaged and fixed with one of the first locking rods.

[0013] Several second locking mechanisms;

[0014] Locking disc; the locking disc is coaxially arranged with the indexing disc and fixedly connected by a concentric shaft, and the second locking mechanism locks the locking disc.

[0015] According to the indexing mechanism of this utility model embodiment applicable to precision surface treatment machine tools, by setting a first locking mechanism, a second hydraulic cylinder drives a first pressing member, so that the first locking groove and the first locking rod engage to fix the indexing plate and prevent the indexing plate from shaking, thus forming the first fixing of the indexing plate; by setting a second locking mechanism and fixing the locking plate through the second locking mechanism, the connection between the locking plate and the base is more stable, that is, the supporting force of the indexing plate is greater, the overall supporting force is greater, and the load is greater, thus forming the second fixing of the indexing plate; through the two fixings of the indexing plate, the overall load can be guaranteed even when the gap is large.

[0016] According to the indexing method applicable to precision surface treatment machine tools in this embodiment of the present invention, the second locking mechanism uniformly locks the locking disc.

[0017] According to the indexing method applicable to precision surface treatment machine tools according to the embodiments of this utility model, the second locking mechanism includes:

[0018] The third hydraulic cylinder includes a cylinder seat;

[0019] The second pressing member has a pressing part at its first end, a middle part of the second pressing member is hinged to the cylinder seat, and a second end of the second pressing member is connected to the output shaft of the third cylinder. The output shaft of the third cylinder pushes up the second end of the second pressing member.

[0020] The locking disc and the indexing disc are fixedly connected by a concentric shaft, forming a second locking groove. The diameter of the locking disc is smaller than that of the indexing disc. The pressing part extends into the second locking groove and, driven by a third hydraulic cylinder, lifts the second end of the second pressing member, causing the pressing part to press the locking disc. Due to the pressing part's pressure on the locking disc, zero gap is achieved between the locking disc and the base, thus achieving a second fixation of the indexing disc. The evenly distributed, uniformly pressed locking disc by the second locking mechanism ensures uniform force on the locking disc and rotating shaft, resulting in a more stable fixation, greater overall support, and a larger load capacity.

[0021] According to the indexing method applicable to precision surface treatment machine tools according to the embodiments of the present invention, the first driving device includes...

[0022] First oil cylinder;

[0023] The first connector, the first end of the first connector is fixedly connected to the output shaft of the first oil cylinder;

[0024] The first fixing member is fixedly connected to the indexing plate and is hinged to the first connecting member. The indexing plate is driven by the first hydraulic cylinder to rotate around the rotation axis at different angles.

[0025] According to the present invention, an indexing mechanism suitable for precision surface treatment machine tools is provided, wherein a positioning groove is provided on the circumferential surface of the indexing plate, and a positioning protrusion is provided at the bottom of the first fixing member. The positioning protrusion is engaged in the positioning groove for positioning and to facilitate installation.

[0026] According to an embodiment of the present invention, an indexing method suitable for precision surface treatment machine tools is provided, wherein the indexing plate is provided with a locking hole in the axial direction, and the first locking rod passes through the locking hole and is fixedly connected to the indexing plate.

[0027] According to the indexing method of this utility model embodiment applicable to precision surface treatment machine tools, there are two locking holes, which are located near the positioning groove and symmetrically arranged on both sides of the positioning groove. Different locking holes are provided depending on the adjustment angle of the indexing plate. In this device, the indexing plate is adjusted to 0 degrees and 22.5 degrees. When the first driving device drives the indexing plate to rotate to 0 degrees or 22.5 degrees, the second hydraulic cylinder drives the first holding member, causing the first locking groove to engage with the first locking rod to fix the indexing plate and prevent it from shaking. A third hydraulic cylinder drives the second holding member, causing the holding part of the second holding member to symmetrically press the locking plate, thereby achieving zero gap between the locking plate and the base, resulting in a more stable fixation, greater overall support force, and greater load capacity.

[0028] The indexing system for precision surface treatment machine tools according to an embodiment of the present invention also includes a base, and the rotating shaft is rotatably connected to the base; the first oil cylinder, the second oil cylinder, and the third oil cylinder are all fixed on the base.

[0029] According to one embodiment of the present invention, the first locking mechanism further includes

[0030] The first slide rail is fixedly connected to the base;

[0031] The first slide plate has a first groove on one side that matches the first slide rail. The first slide plate is slidably connected to the first slide rail through the first groove. The other side of the first slide plate is fixedly connected to the first pressing member. The second hydraulic cylinder drives the first pressing member to move along the direction of the first slide rail.

[0032] According to the indexing of the precision surface treatment machine tool according to the embodiment of the present utility model, the first locking groove is an isosceles trapezoidal structure to prevent damage to the opening of the first pressing member when the second oil cylinder presses the first pressing member when the first driving device drives the indexing plate to not be in position; the isosceles trapezoid can also make the indexing plate rotate into position by pressing the first locking rod when the first driving device drives the indexing plate to not be in position.

[0045] The indexing method applicable to precision surface treatment machine tools according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 3 As shown, an indexing mechanism suitable for precision surface treatment machine tools includes an indexing plate 100, a rotating shaft 200, a first drive device 300, a first locking mechanism 400, several second locking mechanisms 500, a locking plate 600, and a base 700. The first locking mechanism 400 includes a second hydraulic cylinder 410, a first pressing member 420, and several first locking rods 430. Its function is to enable the second hydraulic cylinder 410 to drive the first pressing member 420, thereby engaging the first locking groove 421 with the first locking rod 430. The indexing plate 100 is fixed to prevent it from shaking, thus forming the first fixation of the indexing plate 100. A second locking mechanism 500 is set up to fix the locking plate 600, thereby achieving a more stable connection between the locking plate 600 and the base 700. This means that the supporting force of the indexing plate 100 will be greater, the overall supporting force will be greater, and the load will be greater, thus forming the second fixation of the indexing plate 100. Through the two fixations of the indexing plate 100, the overall load can be guaranteed even when the gap is large.

[0047] like Figure 2 and Figure 3As shown, the first locking rod 430 is integrally formed and includes a limiting part and a locking part. The locking part passes through the locking hole 110 and fixes the first locking rod 430 to the indexing plate 100 through the limiting part. The first locking groove 421 engages with the locking part that passes through the locking hole 110 to fix the indexing plate 100.

[0048] Specifically, such as Figures 1-3 As shown, the first locking mechanism 400 also includes a first slide rail 440 and a first slide plate 450. The first slide rail 440 is fixedly connected to the base 700. One side of the first slide plate 450 is provided with a first slide groove that matches the first slide rail 440. The first slide plate 450 is slidably connected to the first slide rail 440 through the first slide groove. The other side of the first slide plate 450 is fixedly connected to the first pressing member 420. The second hydraulic cylinder 410 drives the first pressing member 420 to move along the direction of the first slide rail 440.

[0049] As a preferred option, such as Figures 1-3 As shown, the first locking groove 421 is an isosceles trapezoidal structure to prevent damage to the opening of the first locking groove 421 of the first pressing member 420 when the second oil cylinder 410 presses the first pressing member 420 when the first driving device 300 fails to drive the indexing plate 100 into position; the isosceles trapezoidal shape can also make the indexing plate 100 rotate into position by pressing the first locking rod 430 through the first pressing member 420 when the first driving device 300 fails to drive the indexing plate 100 into position.

[0050] Specifically, the rotating shaft 200 is perpendicular to the indexing plate 100 and is fixedly connected to the axis of the indexing plate 100; the first driving device 300 drives the indexing plate 100 to rotate at different angles around the rotating shaft 200 as the axis.

[0051] In one embodiment, such as Figures 1-3 As shown, the first locking mechanism 400 includes a second hydraulic cylinder 410, a first pressing member 420, and a plurality of first locking rods 430; the upper end of the first pressing member 420 is fixedly connected to the output shaft of the second hydraulic cylinder 410, and the lower end of the first pressing member 420 is provided with a first locking groove 421; the first locking rods 430 are fixedly connected to the indexing plate 100, and the first pressing member 420 is driven by the second hydraulic cylinder 410, so that the first locking groove 421 is engaged and fixed with one of the first locking rods 430, wherein the fixed position of the first locking rod 430 is determined according to the angle that the indexing plate 100 needs to rotate, as well as the distance between two adjacent first locking rods 430; Figure 5 As shown, the locking disc 600 and the indexing disc 100 are coaxially arranged and fixedly connected by a concentric shaft, and the second locking mechanism 500 locks the locking disc 600.

[0052] As a preferred option, such as Figure 5As shown, the locking plate 600, the indexing plate 100, and the concentric shaft are integrally formed and have a coaxial structure, which facilitates subsequent processing and installation.

[0053] As a preferred option, such as Figures 1-3 As shown, there are four second locking mechanisms 500, among which the second locking mechanisms 500 uniformly lock the locking disc 600.

[0054] According to one embodiment of the present invention, such as Figure 4 As shown, the second locking mechanism 500 includes a third hydraulic cylinder 510 and a second pressing member 520. The third hydraulic cylinder 510 includes a cylinder seat 511. The first end of the second pressing member 520 is provided with a pressing portion 521. The middle part of the second pressing member 520 is hinged to the cylinder seat 511. The second end of the second pressing member 520 is connected to the output shaft of the third hydraulic cylinder 510. Figure 1 As shown, the output force from the output shaft of the third hydraulic cylinder 510 pushes the second end of the second pressing member 520 upward, causing the first end of the second pressing member 520 to press down on the locking disc 600, thereby fixing the indexing disc 100. Through the pressing of the locking disc 600 by multiple second locking mechanisms 500, a zero-gap relationship is achieved between the locking disc 600 and the base 700, better supporting and fixing the indexing disc 100. The locking disc 600 and the indexing disc 100 are fixedly connected by a concentric shaft, forming a second locking groove 610. The diameter of the locking disc 600 is smaller than the diameter of the indexing disc, and the pressing part 521 extends into it. The second locking groove 610, driven by the third hydraulic cylinder 510, pushes the second end of the second pressing member 520 upward, causing the pressing part 521 to move downward to press the locking disc 600, thereby achieving the second fixation of the indexing disc 100. Several second locking mechanisms 500 are evenly arranged. Through the even pressing of the locking disc 600 by the second locking mechanisms 500, the force on the locking disc 600 and the rotating shaft 200 is evenly distributed, which can achieve zero gap between the locking disc 600 and the base 700, that is, the locking disc 600 and the base 700 are formed into a whole, the overall structure is more stable, the support is stronger, and the load is greater.

[0055] Among them, such as Figure 4 As shown, a first hinge groove 512 is provided on the cylinder seat 511, and a second pressing member 520 is hinged in the first hinge groove 512, and the middle part of the second pressing member 520 is hinged to the cylinder seat 511.

[0056] According to one embodiment of the present invention, such as Figure 1 and Figure 3As shown, the first driving device 300 includes a first hydraulic cylinder 310, a first connecting member 320, and a first fixing member 330. The first end of the first connecting member 320 is fixedly connected to the output shaft of the first hydraulic cylinder 310; the first fixing member 330 is fixedly connected to the indexing plate 100, and the first fixing member 330 is hinged to the first connecting member 320. Figure 6 As shown, the first fixing member 330 is provided with a second hinge groove 331, and the second end of the first connecting member 320 is hinged to the first fixing member 330 through the second hinge groove 331. The indexing plate 100 is driven by the first oil cylinder 310 to rotate at different angles around the rotating shaft 200 as the axis.

[0057] In other words, such as Figure 6 As shown, a positioning groove 120 is provided on the circumferential surface of the indexing plate 100, and a positioning protrusion 332 is provided at the bottom of the first fixing member 330. The positioning protrusion 332 is engaged in the positioning groove 120 for positioning and to facilitate installation.

[0058] As a preferred option, such as Figure 5 As shown, the indexing plate 100 is provided with a locking hole 110 in the axial direction, and the first locking rod 430 passes through the locking hole 110 and is fixedly connected to the indexing plate 100.

[0059] Specifically, such as Figure 5 As shown, there are two locking holes 110, which are located near the positioning groove 120 and symmetrically arranged on both sides of the positioning groove 120, facilitating the setting of the angle at which the first driving device 300 drives the indexing plate 100 to rotate. Figure 1 As shown, depending on the angle of adjustment of the indexing plate 100, different locking holes 110 are provided on the indexing plate 100. The indexing plate 100 of this device can be adjusted to 0 degrees and 22.5 degrees. When the first driving device 300 drives the indexing plate 100 to rotate to 0 degrees or 22.5 degrees, the second hydraulic cylinder 410 drives the first pressing member 420, so that the first locking groove 421 and the first locking rod 430 are engaged to fix the indexing plate 100 and prevent the indexing plate 100 from shaking; and the third hydraulic cylinder 510 drives the second pressing member 520, so that the pressing part 521 of the second pressing member 520 evenly presses the locking plate 600, thereby achieving zero gap between the locking plate 600 and the base 700, that is, the locking plate 600 and the base 700 form a whole, the overall structure is more stable, the support is stronger, and the load is greater.

[0060] According to one embodiment of the present invention, such as Figure 1 As shown, it also includes a base 700, and a rotating shaft 200 is rotatably connected to the base 700; the first hydraulic cylinder 310, the second hydraulic cylinder 410 and the third hydraulic cylinder 510 are all fixed on the base 700 and supported by the base 700.

[0061] During operation, the first hydraulic cylinder 310 drives the indexing plate 100 to rotate to a set position, and the second hydraulic cylinder 410 drives the first pressing member 420 to slide along the first slide rail 440, locking the first locking groove 421 onto the first locking rod 430. Since the first locking rod 430 is fixed to the indexing plate 100, the first fixing of the indexing plate 100 is achieved. Then, the output shaft of the third hydraulic cylinder 510 outputs force to push the second end of the second pressing member 520 upward, and the first end of the second pressing member 520 presses down on the locking plate 600, thereby fixing the indexing plate 100. Through the pressing of the locking plate 600 by multiple second locking mechanisms 500, the locking plate 600 and the base 700 can achieve zero clearance, which better supports and fixes the indexing plate 100.
