Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and particularly designs a blocking mechanism. Background Art

[0002] During the production process of automotive parts, goods need to be temporarily blocked to facilitate operations such as packaging or labeling. The blocking of goods is achieved by a blocking mechanism. Existing blocking mechanisms usually use blocking cylinders, which are often called fixed-rod cylinders because of their fixed working stroke.

[0003] When in use, the blocking cylinder is usually installed vertically. The blocking cylinder drives the buffer installed on the driving rod to extend so that the cargo can contact the hydraulic buffer installed on the cylinder rod from the side of the blocking cylinder and stop. In this process, although the impact force of the cargo is buffered by the buffer, the final impact force still needs to be absorbed and borne by the blocking cylinder. The driving rod is easily bent and deformed due to the impact force, which shortens the life of the blocking cylinder; and when the blocking cylinder stops the cargo, its contact surface with the cargo is small, which can easily cause damage to the contact surface or the surface of the cargo during stopping. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to invent a blocking mechanism that can prevent the impact force of the goods from acting on the drive assembly during blocking, causing deformation of the drive assembly, and extend the service life of the blocking mechanism.

[0005] A blocking mechanism includes a driving component, a blocking component and a fixed seat. The blocking component can be slidably installed on the fixed seat. The driving end of the driving component is connected to the blocking component to drive the blocking component to slide upward or downward along the height direction of the fixed seat.

[0006] Furthermore, the blocking assembly includes a blocking plate, a slider and a slide rail, the slider is fixedly mounted on the blocking plate, the slide rail is fixedly mounted on the fixing seat, and the slider is slidably connected to the slide rail.

[0007] Furthermore, there are two of the sliders and two of the slide rails, and the two slide rails correspond to the sliders one-to-one. The two sliders are respectively arranged at both ends of the length direction of the blocking plate.

[0008] Furthermore, the driving assembly includes a driving cylinder, a driving seat and a driving rod. The driving seat is installed on the driving end of the driving cylinder. A slide groove is provided on the blocking assembly. One end of the driving rod is fixed to the driving seat, and the other end is placed in the slide groove and is slidably connected to the slide groove. It is suitable for sliding along the slide groove under the drive of the driving cylinder to drive the blocking assembly to slide upward or downward along the height direction of the fixed seat.

[0009] Furthermore, the driving assembly further includes a supporting guide rail and a supporting slider slidably connected to the supporting guide rail, the supporting guide rail is fixedly mounted on a fixing seat, and the supporting slider is fixedly mounted on the driving seat.

[0010] Furthermore, the driving direction of the driving cylinder is perpendicular to the moving direction of the blocking assembly.

[0011] Furthermore, a bearing is installed on the outer surface of one end of the driving rod placed on the sliding groove, and the driving rod is slidably connected to the sliding groove through the bearing.

[0012] Beneficial effects:

[0013] In the present invention, the original method of using a blocking cylinder to stop the workpiece is replaced with the current method of using a blocking component driven by a driving component to stop the workpiece. Compared with the traditional method of using a blocking cylinder to stop the workpiece, the blocking component to stop the workpiece has a larger contact surface with the workpiece. When the impact force given by the workpiece remains unchanged, it can effectively reduce the pressure on the contact surface between the blocking component and the workpiece during stopping, thereby reducing the probability of damage to the blocking component due to excessive pressure on the contact surface when stopping, effectively extending the service life, and reducing the probability of damage to the goods; in addition, the blocking component is slidably connected to the fixed seat, so that when the blocking component is subjected to the impact of the workpiece, the fixed seat can withstand part of the impact force acting on the blocking component, so as to reduce the probability of the blocking component bending due to the impact, and at the same time avoid the impact force acting on the driving component.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components.

[0023] like Figure 1-3 As shown, a blocking mechanism includes a driving component 10, a blocking component 20 and a fixed base 30. The blocking component 20 can be slidably installed on the fixed base 30. The driving end of the driving component 10 is connected to the blocking component 20 to be suitable for driving the blocking component 20 to slide upward or downward along the height direction of the fixed base 30.

[0024] In the present invention, the original method of using a blocking cylinder to stop the workpiece is replaced with the current method of using a blocking component 20 driven by a driving component 10 to stop the workpiece; compared with the traditional method of using a blocking cylinder to stop the workpiece, the blocking component 20 to stop the workpiece has a larger contact surface with the workpiece. When the impact force given by the workpiece remains unchanged, the pressure on the contact surface between the blocking component 20 and the workpiece during stopping can be effectively reduced, thereby reducing the probability of damage to the blocking component 20 due to excessive pressure on the contact surface when stopping, effectively extending the service life, and reducing the probability of damage to the goods; in addition, the blocking component 20 is slidably connected to the fixed seat 30, so that when the blocking component 20 is subjected to the impact of the workpiece, the fixed seat 30 can withstand part of the impact force acting on the blocking component 20, so as to reduce the probability of the blocking component 20 bending due to the impact, and at the same time avoid the impact force acting on the driving component 10.

[0025] During the blocking operation, the driving component 10 drives the blocking component 20 to move upward along the height direction of the fixing seat 30 until it reaches the maximum stroke; the workpiece will contact the blocking component 20 from the side of the blocking component 20 and be blocked by the blocking component 20.

[0026] Specifically, in order to facilitate the sliding of the blocking component 20, in this embodiment, the blocking component 20 includes three parts: a blocking plate 201, a slider 202 and a slide rail 203, wherein the blocking plate 201 is the part that directly contacts the workpiece, the slider 202 is fixedly installed on the blocking plate 201, the slide rail 203 is fixedly installed on the fixed seat 30, and the slider 202 is slidably connected to the slide rail 203. When performing the blocking operation, the driving component 10 drives the blocking component 20 to move along the slide rail 203, that is, to slide upward along the height direction of the fixed seat 30, so that it can contact the workpiece to stop the workpiece.

[0027] In order to enhance the bearing capacity of the blocking plate 201, in this embodiment, two sliders 202 and two slide rails 203 are provided, and the two slide rails 203 correspond to the sliders 202 one by one. In order to ensure uniform force, the two sliders 202 are respectively provided at both ends of the length direction of the blocking plate 201.

[0028] In addition, in order to reduce the impact force transmitted to the driving component 10 when the blocking component 20 stops the workpiece, in this embodiment, the driving component 10 is divided into three parts: a driving cylinder 101, a driving seat 102 and a driving rod 103, wherein the driving seat 102 is installed on the driving end of the driving cylinder 101, and then a sliding groove 2011 is opened on the blocking component 20, one end of the driving rod 103 is set in the sliding groove 2011, and the other end of the driving rod 103 is connected to the driving seat 102. When working, the driving cylinder 101 can drive the driving rod 103 to slide in the sliding groove 2011 through the driving seat 102, and the driving rod 103 squeezes the inner wall of the sliding groove 2011 And relative to each other, so as to drive the blocking component 20 to move upward or downward along the height direction of the fixing seat 30; since the axial direction of the driving rod 103 is the same as the direction in which the blocking component 20 is subjected to the impact force, and the driving rod 103 and the slide groove 2011 are able to slide relatively, when the blocking component 20 is subjected to an impact, the blocking component 20 will be relatively displaced with the driving rod 103 to reduce the impact force received by the driving rod 103, and then cooperate with the driving seat 102 connecting the driving rod 103 and the driving cylinder 101 to buffer again, which can reduce the impact received by the driving cylinder 101, reduce the probability of the driving rod 103 bending and the driving cylinder 101 being damaged, and extend its service life.

[0029] In addition, in order to reduce the friction between the driving rod 103 and the slide groove 2011 and reduce the loss caused by friction, a bearing is installed on the outer surface of one end of the driving rod 103 placed in the slide groove 2011. The driving rod 103 is slidingly connected to the slide groove 2011 through the bearing to convert the friction between the driving rod 103 and the slide groove 2011 from static friction to dynamic friction.

[0030] At the same time, in order to facilitate the driving cylinder 101 to drive the driving seat 102 to move, in this embodiment, the driving assembly 10 also includes a support guide rail 104 and a support slider 105 slidably connected to the support guide rail 104. The support guide rail 104 is fixedly installed on the fixed seat 30, and the support slider 105 is fixedly installed on the driving seat 102.

[0031] In addition, due to the height limitation of the floor, the space in the workshop in the height direction is relatively insufficient. To solve this problem, in this embodiment, the driving direction of the driving cylinder 101 is set to be perpendicular to the movement direction of the blocking assembly 20, that is, the driving cylinder 101 is installed horizontally, thereby reducing the overall height of the blocking mechanism.

[0032] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
