[0002] Honing, also known as boring, is a finishing process performed on the finished surface using an oilstone embedded in the honing head. In order to improve work efficiency, most of the current honing machines use CNC honing machines and use mechanical claws to automatically load and unload materials. However, traditional CNC honing machines not only require manual cooperation for mechanical claw loading and unloading, but also require manual cooperation for the inspection of workpieces after processing. For example, when loading and unloading mechanical claws, the workpiece needs to be manually placed and loaded and unloaded by the mechanical claws; when inspecting, the workpiece needs to be manually placed on a special inspection device to check whether it is qualified, which greatly reduces production efficiency and does not achieve fully automated honing processing.

DETAILED DESCRIPTION

[0027] The present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0028] See also Figure 1~2The horizontal automatic honing machine shown includes a frame 1, a fixture 2 slidably set on the frame 1, a mechanical claw 3 slidably and rotatably set on the frame 1 and used to grab a workpiece, a storage bin 5 for placing workpieces to be processed, a detection unit 4 set on the frame 1 and used to detect whether the workpiece is qualified after processing, a product bin 7 for storing qualified workpieces after detection, and a waste bin 8 for storing unqualified workpieces after detection. The storage bin 5 and the detection unit 4 are respectively set on both sides of the fixture 2, and the mechanical claw 3 is slidably and rotatably set between the storage bin 5 and the detection unit 4, and the sliding extension direction of the fixture 2 is perpendicular to the sliding extension direction of the mechanical claw 3.

[0029] The storage bin 5 includes a bin seat 5a disposed on the frame 1, a bin body 5b that is rotatably and vibratingly disposed on the bin seat 5a and is used to store the workpieces to be processed, and a feeding channel 5c that is connected to the bin body 5b at one end and is used to transport the workpieces to be processed. The mechanical claw 3 grabs the workpieces to be processed at the other end of the feeding channel 5c. The workpieces to be processed are placed in the bin body 5b in a disorderly manner. Under the action of the rotation and vibration of the bin body 5b, the workpieces to be processed enter the feeding channel 5c in an orderly manner, and then are transported to the grabbing position of the mechanical claw 3 through the feeding channel 5c. The disorderly discharge of materials greatly reduces the loading time.

[0030] The honing machine also includes a slide rail 6 arranged on the frame 1 and extending in the horizontal direction. The mechanical claw 3 includes a base 3a slidably connected to the slide rail 6, a mounting plate 3b rotatably arranged on the base 3a in the horizontal direction, and a clamping assembly 3c for clamping a workpiece and slidably arranged on the mounting plate 3b in the horizontal direction. The clamping assembly 3c includes a first clamping portion, a second clamping portion and a third clamping portion respectively arranged on the mounting plate 3b. A clamping space for accommodating the workpiece is formed between the first clamping portion, the second clamping portion and the third clamping portion, so that one end of the workpiece is located in the clamping space and the other end extends out of the clamping space.

[0031] In this example, the sliding extension direction of the first clamping part and the second clamping part is consistent, and the sliding extension direction of the third clamping part is perpendicular to the sliding extension direction of the first clamping part or the second clamping part. When the workpiece is located in the clamping space, the two opposite sides of the workpiece are respectively abutted against the first clamping part and the second clamping part, and one end of the workpiece is abutted against the third clamping part.

[0032] In this example, the product bin 7 and the waste bin 8 are arranged in sequence along the sliding extension direction of the mechanical claw 3. The honing machine also includes a product channel 9 arranged between the mechanical claw 3 and the product bin 7 and a waste channel 10 arranged between the mechanical claw 3 and the waste bin 8.

[0033] See also Figure 3~4The fixture 2 used in the honing machine is a floating fixture, which includes a bracket 2a slidably set on the frame 1, a fixture body 2b that is rotated by a rotating shaft 2g and slidably set on the bracket 2a, a connecting rod 2c whose one end is connected to the fixture body 2b and the other end passes through the bracket 2a, and a positioning mechanism that is set on two opposite sides of the connecting rod 2c and is respectively matched with or separated from the connecting rod 2c. The connecting rod 2c has a fixed state and an active state. When the positioning mechanisms on both sides cooperate with the connecting rod 2c, the connecting rod 2c is in a fixed state, thereby making the fixture body 2b in a fixed state, which is convenient for the mechanical claw 3 to load and unload; when the positioning mechanisms on both sides are separated from the connecting rod 2c, the connecting rod 2c is in an active state, thereby making the fixture body 2b in an active state, which is convenient for the workpiece to remain floating during the honing process and ensure the honing accuracy.

[0034] The bracket 2a includes a base slidably disposed on the frame 1 and two supporting seats disposed on the base. The clamp body 2b is rotated by a rotating shaft 2g and slidably disposed on the supporting seat and is located between the two supporting seats. The connecting rod 2c is disposed through the base.

[0035] The positioning mechanism and the fixture body 2b are respectively located on two opposite sides of the base of the bracket 2a. Each positioning mechanism includes a positioning rod 2d movably arranged on the base of the bracket 2a to match or separate with the connecting rod 2c, a driving unit for driving the positioning rod 2d to match or separate with the connecting rod 2c, and a positioning groove arranged on the side of the connecting rod 2c corresponding to the position of the positioning rod 2d. When the connecting rod 2c is in a fixed state, the positioning rod 2d is inserted into the positioning groove; when the connecting rod 2c is in an active state, the positioning rod 2d is separated from the positioning groove. In this example, the driving unit is a cylinder 2e, and the end of the positioning rod 2d is fixedly connected to the piston rod of the cylinder 2e, and is inserted into or separated from the positioning groove by the drive of the cylinder 2e.

[0036] The clamp 2 also includes a limiting mechanism for limiting the rotation angle of the clamp body 2b, the limiting mechanism includes a limiting groove 2f opened on the base of the bracket 2a, the other end of the connecting rod 2c is inserted into the limiting groove 2f and moves along the length direction of the limiting groove 2f, and the limiting mechanism also includes an adjusting bolt 2h movably arranged on the bracket 2a and used to adjust the movable distance of the connecting rod 2c in the limiting groove 2f along the length direction of the limiting groove 2f. Specifically, a threaded through hole 2i connected to the limiting groove 2f is provided on the base of the bracket 2a, the length extension direction of the threaded through hole 2i is consistent with the length extension direction of the limiting groove 2f, the adjusting bolt 2h is arranged in the threaded through hole 2i and one end of the adjusting bolt 2h is located in the limiting groove 2f so that the connecting rod 2c can be abutted against the adjusting bolt 2h, and the adjusting bolt 2h moves in the threaded through hole 2i, so that the length of the portion where the adjusting bolt 2h extends into the limiting groove 2f can be adjusted, thereby adjusting the movable distance of the connecting rod 2c in the limiting groove 2f, thereby limiting the rotation angle of the clamp body 2b. The clamp body 2b can also slide a certain distance on the bracket 2a along the extension direction of the rotating shaft 2g through the rotating shaft 2g, and the sliding distance is limited because the clamp body 2b is located between the two support seats.

[0037] In this example, the clamp body 2b is a pneumatic clamp body with a compact structure. The clamp body 2b includes a fixed seat connected to the rotating shaft 2g on both sides and a pneumatic clamp seat arranged on the fixed seat. The pneumatic clamp seat is provided with a clamping position for clamping or releasing the workpiece in the middle. The clamp body 2b is particularly suitable for clamping cylindrical or annular workpieces.

[0038] Through the above-mentioned arrangement, the clamp 2 is installed on the honing machine for use. When the mechanical claw 3 is ready to load material, the cylinder 2e drives the positioning rod 2d to be inserted into the positioning groove, the connecting rod 2c is in a fixed state, the connecting rod 2c is fixedly connected to the clamp body 2b, the clamp body 2b is also in a fixed state, the pneumatic clamping seat is released, and the mechanical claw 3 can load material at this time; when the loading is completed, the pneumatic clamping seat clamps the workpiece, and at the same time, the positioning rod 2d is disengaged from the positioning groove under the action of the cylinder 2e. At this time, the connecting rod 2c is in an active state, and the clamp body 2b rotates and slides on the support seat through the rotating shaft 2g, and the workpiece is in a floating state, and the workpiece can be processed at this time; when the workpiece processing is completed, the positioning rod 2d is inserted into the positioning groove, the connecting rod 2c is fixed, the pneumatic clamping seat, the mechanical claw unloads material, and then loads material, and this is repeated to realize the automatic loading and unloading of the clamp 2.

[0039] Automatic processing of the horizontal automatic honing machine:

[0040] The operator places the workpieces to be processed in the silo body 5b in a disorderly manner. Under the action of the rotation and vibration of the silo body 5b, the workpieces enter the feeding channel 5c in an orderly manner and are transported to the grasping position of the mechanical claw 3 to wait for the mechanical claw 3 to grasp them.

[0041] The mechanical claw 3 grabs the workpiece to be processed, and then slides to the corresponding position of the fixture 2. The mechanical claw 3 rotates to align the workpiece with the clamping position of the fixture 2. The fixture 2 slides toward the mechanical claw 3. The clamping position of the fixture 2 covers the workpiece and clamps the workpiece. Then the fixture 2 retreats and starts honing the workpiece.

[0042] After the honing process is completed, the clamp 2 slides again towards the direction close to the mechanical claw 3, the mechanical claw 3 grabs the workpiece, then rotates and slides towards the direction close to the detection unit 4, the detection unit 4 clamps the workpiece and detects the workpiece. If the detection is qualified, the mechanical claw 3 grabs the workpiece, rotates and slides towards the product bin 7, places the workpiece on the product channel 9, and sends it to the product bin 7 through the product channel 9; if the detection is unqualified, the mechanical claw 3 grabs the workpiece, rotates and slides towards the waste bin 8, places the workpiece on the waste channel 10, and sends it to the waste bin 8 through the waste channel 10.

[0043] When loading the material for the next time, the mechanical claw 3 grabs the workpiece to be processed from the end of the feeding channel 5c and transports it to the corresponding position of the fixture 2. The fixture 2 holds the workpiece tightly, returns, and hones the workpiece. After the processing is completed, the mechanical claw 3 grabs the workpiece and transports it to the detection unit 4 for inspection. This reciprocating process realizes fully automated honing processing and greatly improves efficiency.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
