Description

Technical Field

[0001] This utility model relates to the field of honing machine processing technology, specifically to a honing machine workpiece fixture with redundant buffer. Background Technology

[0002] Reaming, as a high-precision machining method, is widely used for precision machining of internal holes and other parts of workpieces to achieve extremely high dimensional accuracy, shape accuracy, and good surface quality. The reaming machine, as the core equipment in the reaming process, directly affects the quality of the machined workpiece and production efficiency. The workpiece fixture, as a key component in the reaming machine used to fix and position the workpiece, plays a crucial role throughout the entire machining process.

[0003] Reaming requires extremely high positional accuracy from the workpiece; the cutting edge of the tool must be precisely aligned with the workpiece's machining datum surface or a pre-set machining position. Without redundancy, there is a lack of additional adjustment space or error-correction mechanisms during workpiece installation. Even a slight deviation in the installation position makes it difficult to achieve a perfect match between the tool and the workpiece datum through simple adjustments. Without redundancy, each workpiece installation may result in inconsistent repeatability due to variations in operator technique or workpiece inconsistencies. Each reinstallation requires significant time for tool setting to ensure machining accuracy. Utility Model Content

[0004] This utility model provides a workpiece fixture for a honing machine with redundant buffer, which solves the problems of poor positioning accuracy caused by difficulty in alignment during installation and poor machining accuracy caused by repeated tool setting before machining.

[0005] To address the aforementioned problems, this utility model provides a workpiece fixture for a honing machine with redundant buffering, comprising: a base, columns fixed to the two sides of the base, a hexagonal prism with an internal hexagonal through hole located between the two columns and connected to the columns via a first connecting group, a hexagonal prism sleeve located at the center of the hexagonal prism with an internal hexagonal through hole and connected to the hexagonal prism with an internal hexagonal through hole via a second connecting group, a support member located within the hexagonal prism sleeve, a clamping sleeve nested within the support member, several pillars fixed above the base, and a bellows connected between the pillars and the support member via a flange;

[0006] Through the above scheme, the rational layout and connection method of components such as the hexagonal prism with internal hexagonal through holes, hexagonal prism sleeve, first connecting group, second connecting group, and bellows form a redundant buffer structure, providing stable and reliable support and positioning for workpiece clamping. Compared with traditional fixtures, this structure makes it easier for the workpiece to find an accurate positioning position during installation, effectively reducing positioning deviations caused by alignment difficulties during installation, thereby significantly improving positioning accuracy, improving workpiece machining accuracy, ensuring consistent machining quality, and reducing the defect rate.

[0007] According to one embodiment of the present invention, the corrugated pipe is provided with a support spring, and a steel ball is provided below the support spring. The addition of the support spring further strengthens the buffer structure. Through the synergistic effect of the corrugated pipe, the support spring and the steel ball, the impact force brought by the weight of the workpiece can be effectively buffered, reducing damage to other parts of the honing machine and extending the service life of the equipment.

[0008] According to one embodiment of the present invention, a compensator is provided on the outside of the corrugated pipe. Through the above scheme, the compensator makes real-time adjustments to the internal structure or state of the workpiece based on the slight deformation and displacement caused by factors such as force and temperature changes during the workpiece installation process, and compensates for the offset, so that the fixture always maintains a relatively stable state, thereby ensuring the positioning accuracy and processing quality of the workpiece installation.

[0009] According to one embodiment of the present invention, the outer wall of the clamping sleeve is provided with a threaded hole that mates with the first bolt group, and a sliding groove for the first bolt group to slide is provided at the relative position of the support member. With the above solution, after the first bolt group is tightened, the first bolt group is inserted into the sliding groove, and at the same time, the clamping sleeve is nested into the support member. The first bolt has a certain sliding allowance in the sliding groove, which allows the clamping sleeve to be dynamically adjusted within a small range to ensure positioning accuracy.

[0010] According to one embodiment of the present invention, both the first connecting group and the second connecting group are composed of a rotating shaft, a connecting bolt, and an adjusting bolt. Through the above scheme, when the workpiece is clamped and positioned in the honing machine, the rotating shaft allows the components to rotate to a certain extent relative to each other. With the elastic deformation of the connecting bolt and the adjusting bolt, a precise positioning system can be formed. At the same time, the connecting parts form a rigid connection structure, which enhances the stability of the entire fixture structure.

[0011] According to one embodiment of the present invention, the aforementioned rotating shaft is connected to the hexagonal prism with an internal hexagonal through hole by a key. Through the above solution, the key connection achieves a rigid connection between the rotating shaft and the hexagonal prism with an internal hexagonal through hole through the tight fit between the key and the keyway, effectively avoiding relative slippage between the two during torque transmission.

[0012] According to one embodiment of the present invention, the outer wall of the aforementioned hexagonal prism with internal hexagonal through hole is provided with a threaded hole for connecting bolts. When it is necessary to adjust the processing parameters, the fixture component that mates with the connecting bolts can be quickly replaced by loosening the connecting bolts.

[0013] According to one embodiment of this utility model, the aforementioned adjusting bolt is provided with a locking nut. With the above solution, after the adjusting bolt is adjusted to the correct position, the thread friction alone may not be able to completely resist these dynamic forces, and it is easy to loosen. However, the locking nut, through its tight cooperation with the adjusting bolt, generates additional friction and clamping force after tightening, which can effectively resist the bolt loosening caused by vibration and impact, ensuring that the adjusting bolt always remains in the set accurate position and ensuring stable operation of the equipment.

[0014] According to one embodiment of the present invention, the upper wall of the clamping sleeve is provided with a spring pin. With the above solution, when clamping the workpiece, the spring pin can play a quick positioning role. When the workpiece is placed in a suitable position in the clamping sleeve, the spring pin can automatically engage in the preset positioning hole or slot of the workpiece by means of its own elasticity, so as to achieve the initial fixation of the workpiece. There is no need for the operator to perform complex positioning operations manually, which greatly shortens the clamping time of the workpiece and improves the production efficiency. It is especially suitable for batch production scenarios and can effectively reduce the clamping auxiliary time of each workpiece.

[0015] The technical advantages of this application are as follows:

[0016] This application provides a workpiece fixture for a honing machine with redundant buffering. The rational layout and connection of components such as the hexagonal prism with internal hexagonal through holes, the hexagonal prism sleeve, the first connecting group, the second connecting group, and the bellows form a redundant buffering structure, providing stable and reliable support and positioning for workpiece clamping. Compared with traditional fixtures, this structure makes it easier for the workpiece to find an accurate positioning position during installation, effectively reducing positioning deviations caused by alignment difficulties during installation, thereby significantly improving positioning accuracy, improving workpiece machining accuracy, ensuring consistent machining quality, and reducing the defect rate.

Detailed Implementation

[0024] The following will be combined with the appendix Figures 1-5 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0025] Reference Figures 1-5 This utility model provides a workpiece fixture for a honing machine with redundant buffer, comprising: a base 1, columns 2 fixed to the two sides of the base 1, a hexagonal prism 4 with an internal hexagonal through hole located between the two columns 2 and connected to the columns 2 through a first connecting group 3, a hexagonal prism sleeve 10 located at the center of the hexagonal prism 4 with an internal hexagonal through hole and connected to the hexagonal prism 4 through a second connecting group 7, a support member 6 located inside the hexagonal prism sleeve 10, a clamping sleeve 5 nested inside the support member 6, a plurality of support columns 9 fixed above the base 1, and a bellows 8 located between the support column 9 and the support member 6 connected by a flange;

[0026] Through the above scheme, the reasonable layout and connection of components such as the hexagonal prism 4 with internal hexagonal through hole, the hexagonal prism sleeve 10, the first connecting group 3, the second connecting group 7, and the bellows 8 form a redundant buffer structure, providing stable and reliable support and positioning for workpiece clamping. Compared with traditional fixtures, this structure makes it easier for the workpiece to find an accurate positioning position during installation, effectively reducing positioning deviations caused by alignment difficulties during installation, thereby significantly improving positioning accuracy, improving workpiece processing accuracy, ensuring consistent processing quality, and reducing the defect rate.

[0027] The aforementioned bellows 8 is equipped with a support spring 11, and a steel ball 12 is located below the support spring 11. When the workpiece is placed in the mounting position of the honing machine, the weight of the workpiece is applied to the bellows 8. Under pressure, the bellows 8 begins to elastically deform and compress downwards. Simultaneously, the support spring 11 is also compressed, working together with the bellows 8 to absorb the impact force from the workpiece weight. The steel ball 12 provides support and rolls from below, assisting the bellows 8 in buffering and adjustment, allowing the workpiece to be placed stably in the mounting position. As the workpiece is stably placed, the deformation of the bellows 8 and the support spring 11 gradually reaches a relatively stable state. Due to the supporting effect of the steel ball 12 and the elastic characteristics of the bellows 8 and the support spring 11, the bellows 8 can no longer be further adjusted, and the entire structure remains in a fixed position, ensuring the stability of the workpiece installation on the honing machine.

[0028] The above-mentioned bellows 8 is equipped with a compensator on its outer side. Through the above scheme, the compensator can adjust in real time according to the slight deformation and displacement of the fixture caused by factors such as force and temperature changes during the processing. It can automatically adjust its internal structure or state, compensate for the offset, and keep the fixture in a stable state, thereby ensuring the positioning accuracy and processing quality of the workpiece.

[0029] The outer wall of the clamping sleeve 5 is provided with a threaded hole that mates with the first bolt group 13. The support member 6 is provided with a sliding groove 61 for the first bolt group 13 to slide at a relative position. With the above scheme, after the first bolt group 13 is tightened, the first bolt group 13 is inserted into the sliding groove 61. At the same time, the clamping sleeve 5 is nested into the support member 6. The first bolt has a certain sliding allowance in the sliding groove 61, which allows the clamping sleeve 5 to be dynamically adjusted within a small range to ensure positioning accuracy.

[0030] Both the first connecting group 3 and the second connecting group 7 are composed of a rotating shaft 32, a connecting bolt 33, and an adjusting bolt 31. With the above scheme, when the workpiece is clamped and positioned in the honing machine, the rotating shaft 32 allows the components to rotate to a certain extent relative to each other. Combined with the elastic deformation of the connecting bolt 33 and the adjusting bolt 31, a precise positioning system can be formed. At the same time, the connecting parts form a rigid connection structure, which enhances the stability of the entire fixture structure.

[0031] The aforementioned rotating shaft 32 is connected to the hexagonal prism 4 with an internal hexagonal through hole via a key. Through the above scheme, the key connection achieves a rigid connection between the rotating shaft 32 and the hexagonal prism 4 with an internal hexagonal through hole through the tight fit of the key and the keyway, effectively avoiding relative slippage between the two during torque transmission.

[0032] The outer wall of the aforementioned hexagonal prism 4 with internal hexagonal through holes is provided with threaded holes for connecting bolts 33. When it is necessary to adjust the processing parameters, the fixture component that mates with the connecting bolts 33 can be quickly replaced by loosening the connecting bolts 33.

[0033] The aforementioned adjusting bolt 31 is equipped with a locking nut. With the above solution, after the adjusting bolt 31 is adjusted to the correct position, the thread friction alone may not be able to completely resist these dynamic forces, and it is easy to loosen. However, the locking nut, through its tight fit with the adjusting bolt 31, generates additional friction and clamping force after tightening, which can effectively resist the bolt loosening caused by vibration and impact, ensuring that the adjusting bolt 31 always remains in the set accurate position and ensuring stable operation of the equipment.

[0034] The upper wall of the clamping sleeve 5 is provided with a spring pin 51. With the above solution, when clamping the workpiece, the spring pin 51 can play a quick positioning role. When the workpiece is placed in the appropriate position in the clamping sleeve 5, the spring pin 51 can automatically engage in the preset positioning hole or slot of the workpiece by its own elasticity, so as to achieve the initial fixation of the workpiece. There is no need for the operator to perform complex positioning operations manually, which greatly shortens the clamping time of the workpiece and improves the production efficiency. It is especially suitable for batch production scenarios and can effectively reduce the clamping auxiliary time of each workpiece.

[0035] Working principle:

[0036] The workpiece to be processed is placed in the clamping sleeve 5. According to the elastic deformation of the spring pin 51, the head of the spring pin 51 abuts against and fixes the outer wall of the workpiece to be processed. According to the processing technology, the first connecting group 3 or the second connecting group 7 is adjusted so that the hexagonal prism with internal hexagonal through hole drives the hexagonal prism sleeve 10 and the support 6 to swing radially. When making fine adjustments, the hexagonal prism with internal hexagonal through hole 4 is first fixed to the column 2 by the connecting bolt 33. The rotating shaft 32 has scale lines on its side. After rotating the rotating shaft 32 and rotating it a certain angle, the hexagonal prism with internal hexagonal through hole is fixed by the fastening of the adjusting bolt 31 and the locking nut.

[0037] Meanwhile, a support column 9, a bellows 8, a support spring 11, and a steel ball 12 are provided between the base 1 and the support member 6. The bellows 8 and the support spring 11 are compressed, while the steel ball 12 provides support for the bellows 8 and the support spring 11, assisting the bellows 8 in buffering and adjustment. The compensator performs fine-tuning compensation, allowing the workpiece to be placed stably in the installation position. As the workpiece is placed stably, the deformation of the bellows 8 and the support spring 11 gradually reaches a relatively stable state. Due to the supporting effect of the steel ball 12 and the elastic characteristics of the bellows 8 and the support spring 11 themselves, the bellows 8 cannot be further adjusted, and the entire structure remains in a fixed position. The engagement of the bolt 31 and the locking nut is adjusted again to fix the workpiece, ensuring the processing stability of the workpiece on the honing machine.

[0038] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
