Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a machining device for ensuring the accuracy of titanium alloy hole systems. Background Technique

[0002] Titanium alloy refers to a variety of alloy metals made of titanium and other metals; a lathe is a machine tool mainly used to turn a rotating workpiece with a turning tool. Drills, reamers, broaches, taps, dies, and knurling tools can also be used for corresponding machining on the lathe.

[0003] However, when the existing titanium alloy hole system machining device is in use, the titanium alloy thin-walled part to be machined is directly placed on the lathe for processing. However, the dimensional tolerance cannot fully meet the requirements of the drawing. It is not easy to control the clamping force of the clamping structure on the lathe, and the titanium alloy thin-walled part is severely deformed. It is difficult to ensure the accuracy in small-batch production, and the rejection rate is relatively high. Therefore, a machining device for ensuring the accuracy of titanium alloy hole systems is provided. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a machining device for ensuring the accuracy of titanium alloy hole systems. By setting a positioning support plate A, a positioning support plate B, a pressing plate, a clamping screw, a dividing plate, a pin shaft, a locating pin, a V-block, and a fixture body, the utility model solves the problems that when the existing titanium alloy hole system machining device is in use, it is not easy to control the clamping force, the titanium alloy thin-walled part is severely deformed, and it is difficult to ensure the accuracy in small-batch production.

[0005] The technical solution adopted by the utility model to solve its technical problems is a machining device for ensuring the accuracy of titanium alloy hole systems, including a fixture body and a dividing plate. A positioning support plate B is fixed by screws on one side of the dividing plate, and a positioning support plate A for clamping the pump body workpiece is fixed by screws outside the positioning support plate B. A V-block for positioning the pump body workpiece is arranged outside the dividing plate. A pressing plate for clamping the pump body workpiece is arranged outside the dividing plate. A pin shaft for rotating the dividing plate is arranged on the surface of the fixture body. A locating pin entering the inside of the fixture body is arranged on one side of the dividing plate. A hook-shaped pressing plate for locking the dividing plate is movably connected to the outside of the fixture body. A clamping screw for driving the V-block to move is arranged on the surface of the dividing plate.

[0006] By adopting the above technical solution, first place the pump body workpiece on the indexing plate of the fixture body. The positioning support plate A outside the positioning support plate B on the indexing plate contacts the pump body workpiece. Then move the V-block on the indexing plate to make the V-block contact the pump body workpiece. Then use the clamping screw to fix the V-block. Subsequently, use two groups of pressing plates outside the indexing plate to press the pump body workpiece. Then the indexing plate rotates around the pin shaft installed deviating from the rotation axis, install the alignment pin in the two indexing holes of the fixture body for positioning. The indexing plate rotates 180°. Under the action of the spring, the alignment pin is inserted into the second indexing hole on the fixture body. Subsequently, use two groups of hook-shaped pressing plates on the fixture body to lock the indexing plate, and then the second hole on the pump body workpiece can be turned. Thus, the magnitude of the clamping force can be controlled, avoiding deformation of the thin-walled pump body parts made of titanium alloy, ensuring the production accuracy, and greatly reducing the rejection rate of the products.

[0007] Specifically, a transition plate connected to the lathe spindle is provided on one side of the fixture body.

[0008] By adopting the above technical solution, when the fixture body is to be installed on the lathe, the transition plate on the fixture body is connected to the spindle on the lathe, thus facilitating the installation of the fixture body on the lathe.

[0009] Specifically, a protective cover for protecting the fixture body is provided outside the fixture body.

[0010] By adopting the above technical solution, the protective cover provided outside the fixture body reduces the impact force of external objects on the fixture body, thus facilitating the protection of the fixture body.

[0011] Specifically, lubricating oil for reducing friction is applied to the surface of the pin shaft.

[0012] By adopting the above technical solution, the transition plate rotates through the pin shaft on the fixture body, and the lubricating oil applied to the surface of the pin shaft reduces the friction force on the surface of the pin shaft, improving the rotation stability of the transition plate.

[0013] Specifically, convex grain blocks for increasing the friction force on the pump body workpiece are provided on the inner sides of the positioning support plate A and the V-block.

[0014] By adopting the above technical solution, when the positioning support plate A and the V-block clamp the pump body workpiece, the convex grain blocks provided inside the positioning support plate A and the V-block increase the friction force on the surface of the pump body workpiece, enhancing the clamping stability of the pump body workpiece.

[0015] The beneficial effects of the present utility model:

[0016] A processing device for ensuring the accuracy of titanium alloy hole systems according to the present utility model places the pump body workpiece on the indexing plate of the fixture body. The positioning support plate A outside the positioning support plate B on the indexing plate contacts the pump body workpiece. Then, the V-block on the indexing plate is moved so that the V-block contacts the pump body workpiece. Then, the V-block is fixed using a clamping screw. Subsequently, the pump body workpiece is pressed tightly using two groups of pressing plates outside the indexing plate. Then, the indexing plate rotates around the pin shaft installed deviating from the rotation axis, and the alignment pin is installed in two indexing holes of the fixture body for positioning. When the indexing plate rotates 180°, under the action of the spring, the alignment pin is inserted into the second indexing hole on the fixture body. Subsequently, the indexing plate is locked using two groups of hook-shaped pressing plates on the fixture body, and then the second hole on the pump body workpiece can be turned. Thus, the magnitude of the clamping force can be controlled, preventing deformation of the thin-walled pump body parts made of titanium alloy, ensuring production accuracy, and greatly reducing the rejection rate of products.

[0023] To reduce the rejection rate of products, as an embodiment of the present utility model, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a processing device for ensuring the accuracy of titanium alloy hole systems according to the present utility model includes a fixture body 4 and a dividing plate 6. A positioning support plate B2 is fixed to one side of the dividing plate 6 by screws, and a positioning support plate A1 for clamping the pump body workpiece is fixed to the outside of the positioning support plate B2 by screws. A V-shaped block 10 for positioning the pump body workpiece is arranged on the outside of the dividing plate 6, and a pressing plate 9 for clamping the pump body workpiece is arranged outside the dividing plate 6. A pin shaft 7 for rotating the dividing plate 6 is arranged on the surface of the fixture body 4. A locating pin 5 that enters the inside of the fixture body 4 is arranged on one side of the dividing plate 6. A hook-shaped pressing plate 12 for locking the dividing plate 6 is movably connected to the outside of the fixture body 4. A clamping screw 11 for driving the V-shaped block 10 to move is arranged on the surface of the dividing plate 6.

[0024] During use, first place the pump body workpiece on the dividing plate 6 of the fixture body 4. The positioning support plate A1 outside the positioning support plate B2 on the dividing plate 6 contacts the pump body workpiece. Then move the V-shaped block 10 on the dividing plate 6 so that the V-shaped block 10 contacts the pump body workpiece. Then use the clamping screw 11 to fix the V-shaped block 10. Subsequently, use the two groups of pressing plates 9 outside the dividing plate 6 to press the pump body workpiece. Then the dividing plate 6 rotates around the pin shaft 7 installed deviating from the rotation axis, and the locating pin 5 is installed in two indexing holes of the fixture body 4 for positioning. When the dividing plate 6 rotates 180°, under the action of the spring, the locating pin 5 is inserted into the second indexing hole on the fixture body 4. Subsequently, use the two groups of hook-shaped pressing plates 12 on the fixture body 4 to lock the dividing plate 6, and then the second hole on the pump body workpiece can be turned, so that the magnitude of the clamping force can be controlled, avoiding deformation of the thin-walled pump body parts made of titanium alloy, ensuring the production accuracy, and greatly reducing the rejection rate of the products.

[0025] In order to install the fixture body 4 on a lathe, exemplarily, as Figure 2 shown, the present utility model further includes a transition plate 3 arranged on one side of the fixture body 4 and connected to the lathe spindle.

[0026] During use, when the fixture body 4 needs to be installed on a lathe, the transition plate 3 on the fixture body 4 is connected to the spindle on the lathe, thereby facilitating the installation of the fixture body 4 on the lathe.

[0027] In order to protect the fixture body 4, exemplarily, as Figure 2 shown, the present utility model further includes a protective cover 8 arranged outside the fixture body 4 for protecting the fixture body 4.

[0028] During use, the protective cover 8 arranged outside the fixture body 4 reduces the impact force of external objects on the fixture body 4, thereby facilitating the protection of the fixture body 4.

[0029] In order to improve the rotational stability of the transition plate 3, exemplarily, as Figure 2As shown, the utility model further includes that a lubricating oil for reducing friction is applied to the surface of the pin shaft 7.

[0030] During use, the transition plate 3 rotates through the pin shaft 7 on the fixture body 4. The lubricating oil applied to the surface of the pin shaft 7 reduces the friction on the surface of the pin shaft 7 and improves the rotation stability of the transition plate 3.

[0031] To increase the clamping stability of the pump body workpiece, exemplarily, as Figure 1 shown, the utility model further includes that convex grain blocks for increasing the friction on the pump body workpiece are provided on the inner sides of the positioning support plate A1 and the V-shaped block 10.

[0032] During use, when the positioning support plate A1 and the V-shaped block 10 clamp the pump body workpiece, the convex grain blocks provided inside the positioning support plate A1 and the V-shaped block 10 increase the friction on the surface of the pump body workpiece and enhance the clamping stability of the pump body workpiece.

[0033] When the utility model is in use, first place the pump body workpiece on the indexing plate 6 of the fixture body 4. The positioning support plate A1 outside the positioning support plate B2 on the indexing plate 6 contacts the pump body workpiece. Then move the V-shaped block 10 on the indexing plate 6 to make the V-shaped block 10 contact the pump body workpiece. Then use the clamping screw 11 to fix the V-shaped block 10. Subsequently, use the two groups of pressing plates 9 outside the indexing plate 6 to press the pump body workpiece tightly. Then the indexing plate 6 rotates around the pin shaft 7 installed deviating from the rotation axis. Install the alignment pin 5 in two indexing holes of the fixture body 4 for positioning. The indexing plate 6 rotates 180°. Under the action of the spring, the alignment pin 5 inserts into the second indexing hole on the fixture body 4. Subsequently, use the two groups of hook-shaped pressing plates 12 on the fixture body 4 to lock the indexing plate 6, and then the second hole on the pump body workpiece can be turned. Thus, the magnitude of the clamping force can be controlled, preventing deformation of the thin-walled pump body parts made of titanium alloy, ensuring the production precision, and greatly reducing the rejection rate of the products;

[0034] When the fixture body 4 needs to be installed on a lathe, the transition plate 3 on the fixture body 4 is connected to the main shaft on the lathe, facilitating the installation of the fixture body 4 on the lathe;

[0035] The protective cover 8 provided outside the fixture body 4 reduces the impact force of external objects on the fixture body 4, facilitating the protection of the fixture body 4;

[0036] The transition plate 3 rotates through the pin shaft 7 on the fixture body 4. The lubricating oil applied to the surface of the pin shaft 7 reduces the friction on the surface of the pin shaft 7 and improves the rotation stability of the transition plate 3;

[0037] When the positioning support plate A1 and the V-shaped block 10 clamp the pump body workpiece, the convex grain blocks provided inside the positioning support plate A1 and the V-shaped block 10 increase the friction on the surface of the pump body workpiece and enhance the clamping stability of the pump body workpiece.
