Lathe workpiece protection device

Abstract

This utility model discloses a workpiece protection device for lathes, relating to the field of lathe machining technology. In some lathes, the collection box is far from the workpiece, causing the workpiece to experience greater acceleration during its fall and a correspondingly greater impact force upon landing. This affects the protective effect of the buffer pad on the workpiece and increases the risk of workpiece damage. This utility model includes a base and a protective mechanism. The protective mechanism is located at the top of the base and includes a support seat located on one side of the top of the base. This utility model, by incorporating a protective mechanism, a guide plate, a drive motor, and a base, utilizes the drive motor to rotate a lead screw, causing a movable seat outside the lead screw to move up and down.

This allows for convenient collection of workpieces falling from different heights, improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, specifically to a lathe workpiece protection device. Background Technology

[0002] A lathe is a machine tool that primarily uses a cutting tool to machine rotating workpieces. It is the most important type of metal cutting machine tool, and is the most numerous and prevalent type in general machine manufacturing plants, often referred to as the "mother machine." Lathes can also be used to perform various machining operations using drills, reamers, taps, dies, and knurling tools. When machining ring-shaped workpieces on a lathe, the final operation is usually to cut and separate the workpiece from the monolithic blank. However, the cut workpiece will fall off the lathe, potentially causing damage. Therefore, a workpiece protection device is needed.

[0003] Regarding the aforementioned technologies, the applicant believes that a lathe workpiece protection device, when in operation, protects falling workpieces by installing a collection box on the lathe base and laying a buffer pad inside the collection box, minimizing damage to the workpiece. However, due to the variety of lathe types and differences in their structural designs, the distance between the collection box and the workpiece varies. In some lathes, the collection box is farther from the workpiece, causing the workpiece to experience greater acceleration during its fall and a correspondingly greater impact force upon landing. This, in turn, affects the protective effect of the buffer pad on the workpiece, increasing the risk of workpiece damage. Utility Model Content

[0004] The purpose of this utility model is to provide a lathe workpiece protection device to solve the problem mentioned in the background art that in some lathes, the collection box is far from the workpiece, which causes the workpiece to gain a large acceleration during the falling process and the impact force generated when it lands is also increased, thereby affecting the protective effect of the buffer pad on the workpiece and increasing the risk of workpiece damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lathe workpiece protection device, comprising a base and a protective mechanism. The protective mechanism is disposed at the top of the base and includes a support seat disposed on one side of the top of the base. A fixed rod is rotatably disposed inside the support seat.

A guide plate is disposed outside the sliding block. A sliding groove is formed at the bottom of the guide plate. The sliding block is slidably disposed inside the sliding groove. A discharge groove is formed inside the guide plate.

[0006] By adopting the above technical solution, the operation of the drive motor can drive the lead screw to rotate, causing the movable seat outside the lead screw to move up and down. Through the transmission of the movable rod, one end of the guide plate can be moved, thereby facilitating the adjustment of the height of one end of the guide plate. This makes it easier to collect workpieces falling from different heights, improving the practicality of the device.

[0008] By adopting the above technical solution, the workpiece can be easily protected, and the workpiece can be prevented from falling off the guide plate as much as possible.

[0009] Preferably, a protective pad is provided on the side of the top of the protective plate away from the baffle, and elastic baffle blocks are evenly provided on the top of the protective pad.

[0010] By adopting the above technical solution, the falling workpiece can be blocked, thereby slowing down the speed at which the workpiece falls.

[0011] Preferably, the top of the base is provided with support frames at both ends on the side away from the support seat, and the support frames are rotatably connected to the guide plate.

[0012] By adopting the above technical solution, the guide plate can be easily supported, thus improving the stability of the guide plate during operation.

[0013] Preferably, the top of the base is provided with a collection groove, which is located below the discharge groove.

In conjunction with the work of the buffer pad, it can effectively protect the falling workpiece and minimize the risk of damage to the workpiece.

[0017] Preferably, the cushioning pad is made of polyurethane, and the elastic cushioning strip is made of rubber.

[0018] By adopting the above technical solution, the impact energy when the workpiece falls can be absorbed.

[0019] Preferably, one end of the base is hinged with a door.

[0020] By adopting the above technical solution, the workpieces collected inside the base can be processed conveniently.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Equipped with a protective mechanism, guide plate, drive motor, and base, the drive motor rotates the lead screw, causing the movable seat outside the lead screw to move up and down.

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1 to 5 This embodiment provides a technical solution: a lathe workpiece protection device, including a base 2 and a protective mechanism 1. The protective mechanism 1 is disposed at the top of the base 2. The protective mechanism 1 includes a support seat 108 fixedly connected to one side of the top of the base 2. A fixing rod 109 is rotatably disposed inside the support seat 108, which can make the fixing rod 109 move inside the support seat 108. A base plate 116 is fixedly connected to the lower part inside the fixing rod 109, and the base plate 116 can provide load-bearing capacity.

[0032] The bottom of the base plate 116 is equipped with a drive motor 117. The drive motor 117 works on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. They are subjected to Ampere force in the magnetic field, generating torque and causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 117, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 117 are existing technologies and will not be described in detail below.

[0033] A lead screw 118 is fixedly connected to the output end of the drive motor 117. A movable seat 115 is provided outside the lead screw 118. A movable rod 114 is provided at the top of the movable seat 115. A sliding block 110 is rotatably mounted at the top of the movable rod 114. A guide plate 104 is provided outside the sliding block 110. A sliding groove is formed at the bottom end of the guide plate 104. The sliding block 110 is slidably disposed inside the sliding groove. Figure 2 As shown, when the movable rod 114 is moved upward under force, it will push the guide plate 104 to move synchronously under the action of the sliding block 110 and the sliding groove. The guide plate 104 has a discharge groove 111 inside. The two ends of the top of the base 2 away from the support seat 108 are fixedly connected to the support frame 103. The support frame 103 is rotatably connected to the guide plate 104, which can conveniently support the guide plate 104 and improve the stability of the guide plate 104 during operation.

[0034] The overall effect of this embodiment is as follows: The drive motor 117 is started by a control switch. The drive motor 117 drives the lead screw 118 to rotate via a coupling, which in turn drives the movable seat 115 outside the lead screw 118 to smoothly rise and fall axially. When the movable seat 115 rises, it pushes the distal end of the guide plate 104 upwards via the movable rod 114, and vice versa, thus adjusting the height of the end of the guide plate 104. The tilt angle of the guide plate 104 can be dynamically adjusted according to the drop height of different lathe workpieces, allowing the workpiece to slide smoothly along the guide plate 104 to the collection area, avoiding high-speed impacts caused by excessive vertical height differences.

[0035] Example 2

[0036] Protective plates 101 are fixedly connected to both sides of the top of the guide plate 104. A baffle 102 is fixedly connected to one side of the top of the guide plate 104, which can conveniently protect the workpiece and prevent the workpiece from falling off the guide plate 104 as much as possible. A protective pad 112 is fixedly connected to the top of the protective plate 101 away from the baffle 102, which can conveniently protect the workpiece. Elastic stop blocks 113 are evenly arranged on the top of the protective pad 112, which can block the falling workpiece and thus slow down the falling speed of the workpiece.

[0037] The effect achieved by the entire second embodiment is that after the workpiece falls onto the guide plate 104, the workpiece can be blocked by the operation of the elastic baffle block 113, thereby slowing down the falling speed of the workpiece.

[0038] Example 3

[0039] The top of the base 2 is provided with a collection groove 107, which can facilitate the collection of workpieces. The collection groove 107 is fixedly connected to the bottom of the discharge groove 111. A buffer pad 105 is fixedly connected to the bottom of the collection groove 107. Elastic buffer strips 106 are evenly arranged on both sides inside the collection groove 107. The buffer pad 105 is made of polyurethane. The elastic buffer strips 106 absorb the impact energy of the workpiece through their own deformation. The elastic buffer strips 106 are made of rubber and can dissipate the remaining impact force of the workpiece. A door 3 is hinged to one end of the base 2.

[0040] The effect achieved by the entire embodiment 3 is as follows: the workpiece falls into the collection tank 107 through the discharge trough 111 on the guide plate 104, and the elastic buffer belt 106 absorbs the impact energy of the workpiece through its own deformation, forming the initial buffer; then the workpiece contacts the buffer pad 105 at the bottom of the collection tank 107, and the honeycomb microporous structure of the buffer pad 105 further dissipates the remaining impact force, which can conveniently protect the workpiece and improve the protection reliability of the device.

[0041] Working principle: First, the base 2 is installed on the lathe. Then, the drive motor 117 is started using a control switch. The drive motor 117 drives the lead screw 118 to rotate through the coupling, which can drive the movable seat 115 outside the lead screw 118 to rise and fall smoothly along the axial direction. When the movable seat 115 rises, it pushes the far end of the guide plate 104 upward through the movable rod 114, and vice versa, thus adjusting the height of the end of the guide plate 104. The tilt angle of the guide plate 104 can be dynamically adjusted according to the drop height of different lathe workpieces, so that the workpiece can slide smoothly along the guide plate 104 to the collection area, avoiding high-speed impact caused by excessive vertical height difference.

[0042] Secondly, the workpiece falls into the collection tank 107 through the discharge chute 111 on the guide plate 104. The elastic buffer belt 106 absorbs the impact energy of the workpiece through its own deformation, forming the initial buffer. Subsequently, the workpiece contacts the buffer pad 105 at the bottom of the collection tank 107. The honeycomb microporous structure of the buffer pad 105 further dissipates the remaining impact force, which can conveniently protect the workpiece and improve the protection reliability of the device.
