Description

Technical Field

[0001] This utility model relates to a steel ball reverse support device. Background Technology

[0002] Some oil passage holes on the car cylinder block need to be sealed with steel balls. The existing method of sealing with steel balls is for workers to use a copper rod to knock the steel ball into the hole, and then use a chisel to evenly rivet multiple notches at the hole opening to prevent the steel ball from coming out. Because the force and position of manual knocking are difficult to control, the degree of steel ball riveting will be different due to the different knocking force and knocking location, which can easily lead to inconsistent product quality, and may even cause leakage in the oil passage hole.

[0003] Therefore, the manual installation of steel balls has been replaced with automatic installation using a riveting device. Compared to manual installation, automatic installation ensures consistent product quality standards. Currently, the steel ball installation method involves an industrial robot gripping the cylinder and moving it between the first riveting device and the main oil passage push rod. The first riveting device rivets the steel ball in the main oil passage. Then, the industrial robot grips the cylinder and moves it between the second riveting device and multiple push rods. After the industrial robot corrects its position, the second riveting device rivets the steel ball in the auxiliary oil passage hole. This process requires the industrial robot to make two significant movements and corrections to move the steel ball from the main oil passage to the auxiliary oil passage hole, which affects the installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a steel ball reverse support device to solve the problem that existing steel ball reverse support devices require large-scale robot movement and correction, which affects the installation efficiency of steel balls.

[0005] To solve the above problems, the technical solution of this utility model is as follows:

[0006] A steel ball reverse support device includes a support base, one end of which is connected to a guide base. The guide base has intersecting first and second through holes. First guide sleeves are fitted at both ends of the first through holes. A slide block, located within the first through hole, has both ends fitted into the first guide sleeves at both ends of the first through hole. A first cylinder is installed at one end of each first guide sleeve, with its piston rod fixedly connected to one end of the slide block. A first push rod is fixedly connected to the other end of the slide block. An insertion hole communicating with the second through hole is provided on the slide block. Second guide sleeves are fitted at both ends of the second through hole. A slider is fitted within one of the second guide sleeves. A second cylinder is installed at one end of this second guide sleeve, with its piston rod connected to one end of the slider. The second cylinder drives the slider to pass through the insertion hole and insert into the other second guide sleeve. Multiple second push rods are fitted on the end face of the guide base.

[0007] A mounting plate is detachably mounted on the end face of the guide seat, and each second push rod is connected to the mounting plate.

[0008] The guide seat is detachably connected to one end of the support seat by screws. Multiple pressure blocks are installed on the top surface of the support seat, and the upper end of the support seat abuts against the pressure blocks.

[0009] The slide is rectangular, and the insertion hole on the slide is square.

[0010] The beneficial effects of this utility model are as follows: the main oil passage is first supported in the reverse direction by the first push rod, and then the steel ball is installed in the main oil passage by the first riveting device. Next, the second cylinder drives the slider to pull out the insertion hole, and then the first cylinder drives the first push rod to retract. The robot moves slightly to let the cylinder body abut against each of the second push rods, so that the second push rods support the cylinder body in the reverse direction. The steel ball is installed in the auxiliary oil passage by the second riveting device. In this way, the robot can complete the riveting installation of the steel balls in the main oil passage and auxiliary oil passage with only a small amount of translation, which shortens the movement and correction time of the industrial robot and improves the installation efficiency and accuracy of the steel balls.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, a steel ball reverse support device includes a support base 1, one end of which is connected to a guide seat 3. A first through hole and a second through hole are provided in the guide seat 3, the first through hole and the second through hole intersecting perpendicularly. First guide sleeves 9 are respectively fitted at both ends of the first through hole. A slide block 11 disposed in the first through hole has both ends fitted into the first guide sleeves 9 at both ends of the first through hole. A first cylinder 8 is installed at one end of the first guide sleeve 9, the piston rod of the first cylinder 8 is fixedly connected to one end of the slide block 11, and a first push rod 7 is fixedly connected to the other end of the slide block 11. An insertion hole communicating with the second through hole is opened on the slide block 11, and the slide block 11 is driven by the first cylinder 8 to move along... The slide block 11 moves along the axis of the first guide sleeve 9; second guide sleeves 10 are respectively installed at both ends of the second through hole, and a slider 12 is installed in one of the second guide sleeves 10. A second cylinder 4 is installed at one end of the second guide sleeve 10. The piston rod of the second cylinder 4 is connected to one end of the slider 12. The second cylinder 4 is used to drive the slider 12 through the insertion hole and insert it into the other second guide sleeve 10. In this way, both ends of the slider 12 are fixed by the two first guide sleeves 9 to fix and limit the slide block 11. In order to facilitate the insertion of the slider 12 into the insertion hole and the other second guide sleeve 10, a chamfer is provided at one end of the slider 12; multiple second push rods 6 are installed on the end face of the guide seat 3.

[0022] The method of using this utility model is as follows:

[0023] S1: As Figure 6 and 7 As shown, the industrial robot 15 grips the cylinder 14 between the two riveting devices 13 and the reverse support device. The industrial robot 15 moves one end of the main oil passage of the cylinder 14 to abut against one end of the first push rod 7. The first push rod 7 provides reverse support for the main oil passage of the cylinder 14. Then, the first riveting device 13 rivets the steel ball into the main oil passage. Since the main oil passage is a through hole parallel to the axis of the cylinder 14 and is located in the middle area of ​​the cylinder 14, only one first push rod 7 needs to hold one end of the main oil passage. The first riveting device 13 can directly rivet the steel ball to the other end of the main oil passage. Moreover, it can ensure that the riveting is applied vertically and the cylinder 14 will not be deflected.

[0024] S2: After the steel ball in the main oil passage is riveted, the second cylinder 4 first pulls the slider 12 out of the insertion hole, then the first cylinder 8 drives the first push rod 7 to retract about 50cm. Then the industrial robot 15 moves to the right, so that at least three support surfaces at one end of the auxiliary oil passage of the cylinder body 14 abut against each of the second push rods 6. Each of the second push rods 6 forms a support surface at one end of the auxiliary oil passage of the cylinder body 14. The hole of the steel ball to be riveted in the auxiliary oil passage is located in this support surface. Since the holes at both ends of the auxiliary oil passage are not on the same axis or the hole of the auxiliary oil passage to be installed with the steel ball is a blind hole, the auxiliary oil passage needs at least three second push rods 6 to provide reverse support.

[0025] S3: The second riveting device 13 installs steel balls in the auxiliary oil passage. After installation, the robot can complete the riveting installation of steel balls in the main oil passage and auxiliary oil passage with only a small translation, which shortens the movement and correction time of the industrial robot 15 and improves the installation efficiency and accuracy of the steel balls.

[0026] In addition, when the riveting device 13 rivets the steel ball, the pressure applied to the cylinder 14 is about 2 to 3 tons. If the interlocking locking structure of the slide block 11 and the slider 12 is not set, the first cylinder 8 will be displaced due to air compression when riveting the main oil passage steel ball, or even burst the pipe, ultimately causing the main oil passage steel ball to fail to be riveted. Therefore, the first push rod 7 needs to be mechanically locked.

[0027] A mounting plate 5 is detachably mounted on the end face of the guide seat 3 via screws, and each second push rod 6 is connected to the mounting plate 5. When steel ball riveting is required for other models of cylinder 14, the mounting plate 5 can be directly replaced to replace each second push rod 6, enabling this utility model to quickly adapt to different models of cylinder 14 and improve work efficiency.

[0028] The guide seat 3 is detachably connected to one end of the support seat 1 by screws. Multiple pressure blocks 2 are installed on the top surface of the support seat 1, and the upper end of the support seat 1 abuts against the pressure blocks 2. When the guide seat 3 needs to be replaced, the upper end of the guide seat 3 is placed against the pressure blocks 2, and the pressure blocks 2 position the guide seat 3 vertically, thereby improving the replacement efficiency of the guide seat 3.

[0029] The slide 11 is rectangular, and the insertion hole on the slide 11 is a square hole. This structure of the slide 11 makes it easy to process and manufacture.

[0030] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
